18 Proprietary and Confidential - Contents subject to change 2400074 2: Technology Overview 2 LTE LTE (Long Term Evolution) is a 4th-generation wireless standard. The 3GPP Release 8 specification outlines the features and requirements. Key features include.

Peak data rate:

100 Mbps DL within 20 MHz bandwidth

(Peak DL data rate in 10 MHz bandwidth: 70 Mbps (approx.) for Cat 3 device) 50 Mbps UL within 20 MHz bandwidth Actual throughput is dependent on the network configuration, bandwidth assigned to the UE, the number of users, and RF sig-

nal conditions. Up to 200 active users in a cell (5 MHz) Less than 5 ms user-plane latency Supported bandwidths: 5 MHz / 10 MHz Spectrum flexibility: 1.420 MHz (320 MHz in future F/W release) Enhanced support for end-to-end QOS Physical layer uses:

DL: OFDMA (Orthogonal Frequency Division Multiple Access). Modulation: QPSK, 16QAM, and 64QAM UL: Single Carrier FDMA (single carrier modulation and orthogonal frequency multiplexing) Modulation: QPSK, 16QAM

MIMO (Multi-Input Multi-Output) antenna support CDMA 1xEV-DO 1xEV-DO is backwards compatible to both 1X and IS-95A/B standards. However, 1xEV-DO represents an evolutionary enhancement, specifically designed and optimized for high-speed wireless data access. This was driven by fundamental differences between voice and data traffic characteristics. Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 19 Product Technical Specification & Customer Design Guidelines eHRPD (Enhanced High Rate Packet Data) is an enhancement of 1xEV-DO that enables LTE to CDMA handover. To optimize for data, there are some fundamental characteristics and differences between 1X and 1xEV-DO, including:

The network has dedicated spectrum (1.25 MHz) for data traffic using 1xEV-DO standard, so resources dont compete with 1X data/voice (hybrid mode used to monitor 1X carriers) BTS always transmits at maximum available power Each user receives data from only one base station at a time (no forward link soft handoff) 1xEV-DO lets each user use 100% of available resources, while dynamically allocating time resources among users for maximum efficiency 1xEV-DO uses time-division multiplexing of users on forward link (slots assigned for packet transmission) Forward link supports higher order modulation (QPSK, 8-PSK and 16-QAM) Reverse link (1xEV-DO Revision A) supports higher order modulation

(8-PSK)

Mobile supports dynamic channel estimation using measured S/N to set the highest rate it can decode (uses Data Rate Control channel to communicate to network access point)

Mobiles can support Rx diversity for S/N enhancements particularly in multi-

path/fading environments 1X and IS-95A The type of data connection made at any given time depends on the services available from the carrier in the given coverage area. If 1X packet services are not available, the modem connects using circuit-switched data over IS-95A technology. The modem automatically selects the fastest connection mode available when a data call is connecting. When roaming, the modem does not automatically change connection modes. If the modem connects using 1X and then roams outside of the packet service area, the connection is dropped. To resume data communication, a new connection using IS-95A has to be created. Similarly, an IS-95A call established in one area does not automatically transition to 1X when the unit enters the 3G coverage area. 20 Proprietary and Confidential - Contents subject to change 2400074 3: Standards Compliance 3 The MC7750 Mini Card complies with the mandatory requirements described in the following standards. The exact set of requirements supported is carrier-dependent. Table 3-1: Standards compliance Technology Standards LTE CDMA

The module includes the following interfaces to the host:

W_DISABLE_N Active low input from a hardware switch to the Power Supplied to the module by the host. MC7750 that disables the main RF radio.

WLAN_LED_N Active-low LED drive signal provides an indication of RADIO ON state, either WAN or GPS. Antenna Three U.FL RF connectors (two for Rx / Tx, and one for GPS). For details, see RF Specifications on page 37. Note that GPS can use either the dedicated GPS port, or the diversity/MIMO port. GLONASS is supported only on the dedicated GPS port. SIM Supported through the interface connector. The SIM cavity / connector must be placed on the host device for this feature. USB Interface to the host for data, control, and status infor-

mation. GPIO Six GPIOs reserved for future use.

(2G) 3GPP TS 51.010-1, section 27.17, or

(3G) ETSI TS 102 230 V5.5.0, section 5.2. When designing the remote SIM interface, you must make sure that SIM signal integrity is not compromised. Some design recommendations include:

Total impedance of the VCC and GND connections to the SIM, measured at the module connector, should be less than 1 to minimize voltage drop

(includes any trace impedance and lumped element components inductors, filters, etc.). Position the SIM connector 10 cm from the module. If a longer distance is required because of the host device design, use a shielded wire assembly connect one end as close as possible to the SIM connector and the other end as close as possible to the module connector. The shielded assembly may help shield the SIM interface from system noise. Reduce crosstalk on the USIM_DATA line to reduce the risk of failures during GCF approval testing. Avoid routing the USIM_CLK and USIM_DATA lines in parallel over distances 2 cm cross-coupling of these lines can cause failures. 3GPP has stringent requirements for I / O rise time (<1 s), signal level limits, and noise immunity consider this carefully when developing your PCB layout. Keep signal rise time <1 s keep USIM signals as short as possible, and keep very low capacitance traces on the USIM_DATA and USIM_CLK signals. High capacitance increases signal rise time, potentially causing your device to fail certification tests. Add external pull-up resistors (15 k30 k), if required, between the USIM_DATA and USIM_PWR lines to optimize the signal rise time. VCC line should be decoupled close to the SIM socket. SIM is specified to run up to 5 MHz (SIM clock rate). Take note of this speed in the placement and routing of the SIM signals and connectors. You must decide whether additional ESD protection is required for your product, as it is dependent on the application, mechanical enclosure, and SIM connector design. The SIM pins will require additional ESD protection if they are exposed to high ESD levels (i.e. can be touched by a user). Putting an optional decoupling capacitor at USIM_PWR near the SIM socket is recommended the longer the trace length (impedance) from the socket to the module, the greater the capacitance requirement to meet compliance tests. Putting an optional series capacitor and resistor termination (to ground) at USIM_CLK at the SIM socket to reduce EMI and increase signal integrity is recommended if the trace length between the SIM socket and module is long 47 pF and 50 resistor are recommended. Test your first prototype host hardware with a Comprion IT3 SIM test device at a suitable testing facility.

O Digital pin Output; PU Digital pin Input, internal pull up Type1 PU O W_DISABLE_N Wireless disable The host device uses W_DISABLE_N (pin 20) to enable / disable the WWAN or radio modem. When disabled, the modem cannot transmit or receive information. Letting this signal float high allows the module to operate normally. This switch follows the behavior described in [11] PCI Express Mini Card Electromechanical Specification Revision 1.2. This pin has a 20 k pull-up resistor. See Figure 4-5 on page 33 for a recommended implementation. When integrating with your host device, keep the following in mind:

The signal is an input to the module and should be driven LOW only for its active state (controlling the power state); otherwise it should be floating or

(High impedance). It should never be driven to a logic high level. The module has an internal pull-up resistor to Module Power (3.3V) in place, so if the signal is floating or (high impedance), the module will power on.

Diversity / MIMO / GPS connector 2 Diversity, MIMO, or GPS The module does not have integrated antennas. I/O connector Main RF connector GPS connector 1 Diversity/MIMO/GPS connector 2 Figure 5-1: Module connectors RF connections When attaching antennas to the module:

Use Hirose U.FL connectors (3 mm x 3 mm, low profile; model U.FL #CL331-0471-0-10) to attach antennas to connection points on the module, as shown in Figure 5-1 on page 37.

Match coaxial connections between the module and the antenna to 50 .

Minimize RF cable losses to the antenna; the recommended

maximum cable loss for antenna cabling is 0.5 dB. To ensure best thermal performance, if possible use the mounting holes to attach (ground) the device to the main PCB ground or a metal chassis. Note: If the antenna connection is shorted or open, the modem will not sustain permanent damage. Shielding The module is fully shielded to protect against EMI and must not be removed. Note: To disconnect the antenna, make sure you use the Hirose U.FL connector removal tool

(P / N UFL-LP-N-2(01)) to prevent damage to the module or coaxial cable assembly. Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 37 Product Technical Specification & Customer Design Guidelines Antenna and cabling When selecting the antenna and cable, it is critical to RF performance to match antenna gain and cable loss. Note: For detailed electrical performance criteria, see Appendix A: Antenna Specification on page 65. Choosing the correct antenna and cabling When matching antennas and cabling:

The antenna (and associated circuitry) should have a nominal impedance of 50 with a return loss of better than 10 dB across each frequency band of operation. The system gain value affects both radiated power and regulatory (FCC, IC, CE, etc.) test results. Designing custom antennas Consider the following points when designing custom antennas:

A skilled RF engineer should do the development to ensure that the RF performance is maintained. If both CDMA and UMTS modules will be installed in the same platform, you may want to develop separate antennas for maximum performance. Determining the antennas location When deciding where to put the antennas:

Antenna location may affect RF performance. Although the module is shielded to prevent interference in most applications, the placement of the antenna is still very important if the host device is insufficiently shielded, high levels of broadband or spurious noise can degrade the modules perfor-

mance. Connecting cables between the module and the antenna must have 50 impedance. If the impedance of the module is mismatched, RF performance is reduced significantly. Antenna cables should be routed, if possible, away from noise sources

(switching power supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna. See Interference from other wireless devices on page 39. Disabling the diversity antenna

For LTE bands, use the AT command !RXDEN=0 to disable receive diversity or

!RXDEN=1 to enable receive diversity. For CDMA bands, use the AT command !DIVERSITY to enable or disable receive diversity.

38 Proprietary and Confidential - Contents subject to change 2400074 RF Specifications Note: A diversity antenna is used to improve connection quality and reliability through redundancy. Because two antennas may experience difference interference effects (signal distortion, delay, etc.), when one antenna receives a degraded signal, the other may not be similarly affected. Ground connection When connecting the module to system ground:

Prevent noise leakage by establishing a very good ground connection to the module through the host connector. Connect to system ground using the two mounting holes at the top of the module (shown in Figure 5-1 on page 37).

Minimize ground noise leakage into the RF. Depending on the host board design, noise could potentially be coupled to the module from the host board. This is mainly an issue for host designs that have signals traveling along the length of the module, or circuitry operating at both ends of the module interconnects. Interference and sensitivity Several interference sources can affect the modules RF performance

(RF desense). Common sources include power supply noise and device-

generated RF. RF desense can be addressed through a combination of mitigation techniques

(Methods to mitigate decreased Rx performance on page 40) and radiated sensitivity measurement (Radiated sensitivity measurement on page 41). Note: The MC7750 is based on ZIF (Zero Intermediate Frequency) technologies. When performing EMC (Electromagnetic Compatibility) tests, there are no IF (Intermediate Frequency) components from the module to consider. Interference from other wireless devices Wireless devices operating inside the host device can cause interference that affects the module. To determine the most suitable locations for antennas on your host device, evaluate each wireless devices radio system, considering the following:

Any harmonics, sub-harmonics, or cross-products of signals generated by wireless devices that fall in the modules Rx range may cause spurious response, resulting in decreased Rx performance. The Tx power and corresponding broadband noise of other wireless devices may overload or increase the noise floor of the modules receiver, resulting in Rx desense.

Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 39 Product Technical Specification & Customer Design Guidelines The severity of this interference depends on the closeness of the other antennas to the modules antenna. To determine suitable locations for each wireless devices antenna, thoroughly evaluate your host devices design. Host-generated RF interference All electronic computing devices generate RF interference that can negatively affect the receive sensitivity of the module. Proximity of host electronics to the antenna in wireless devices can contribute to decreased Rx performance. Components that are most likely to cause this include:

Microprocessor and memory

Display panel and display drivers Switching-mode power supplies Device-generated RF interference The module can cause interference with other devices. Wireless devices such as AirPrime embedded modules transmit in bursts (pulse transients) for set durations

(RF burst frequencies). Hearing aids and speakers convert these burst frequencies into audible frequencies, resulting in audible noise. Methods to mitigate decreased Rx performance It is important to investigate sources of localized interference early in the design cycle. To reduce the effect of device-generated RF on Rx performance:

Put the antenna as far as possible from sources of interference. The drawback is that the module may be less convenient to use. Shield the host device. The module itself is well shielded to avoid external interference. However, the antenna cannot be shielded for obvious reasons. In most instances, it is necessary to employ shielding on the components of the host device (such as the main processor and parallel bus) that have the highest RF emissions. Filter out unwanted high-order harmonic energy by using discrete filtering on low frequency lines. Form shielding layers around high-speed clock traces by using multi-layer PCBs. Route antenna cables away from noise sources.

Radiated Spurious Emissions (RSE) When designing an antenna for use with AirPrime embedded modules, the host device with an AirPrime embedded module must satisfy the radiated spurious emission (RSE) test cases described in:

(CDMA) Refer to CDMA standards for receive-only mode, and local regulatory bodies for transmit mode (transmitter is operating). 40 Proprietary and Confidential - Contents subject to change 2400074 RF Specifications Note that antenna impedance affects radiated emissions, which must be compared against the conducted 50-ohm emissions baseline. (AirPrime embedded modules meet the 50-ohm conducted emissions requirement.) Radiated sensitivity measurement A wireless host device contains many noise sources that contribute to a reduction in Rx performance. To determine the extent of any receiver performance desensitization due to self-

generated noise in the host device, over-the-air (OTA) or radiated testing is required. This testing can be performed by Sierra Wireless or you can use your own OTA test chamber for in-house testing. Sierra Wireless sensitivity testing and desensitization investigation Although AirPrime embedded modules are designed to meet carrier requirements for receiver performance, they are still susceptible to various performance inhibitors. As part of the Engineering Services package, Sierra Wireless offers modem OTA sensitivity testing and desensitization (desense) investigation. For more information, contact your account manager or the Sales Desk (see Contact Information on page 4). Note: Sierra Wireless has the capability to measure TIS (Total Isotropic Sensitivity) and TRP (Total Radiated Power) according to CTIA's published test procedure. Sensitivity vs. frequency For CDMA bands, sensitivity is defined as the input power level in dBm that produces a FER (Frame Error Rate) of 0.5%. Sensitivity should be measured at all CDMA frequencies across each band. For LTE bands, sensitivity is defined as the RF level at which throughput is 95% of maximum.

Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 55 Product Technical Specification & Customer Design Guidelines Thermal considerations Embedded modules can generate significant amounts of heat that must be dissipated in the host device for safety and performance reasons. Transmitter Receiver Baseband 1 Baseband 2 Pin 1 Top Figure 8-4: Shield locations Pin 1 Bottom The amount of thermal dissipation required depends on:

Supply voltage See Chapter 6: Power on page 45 for details of max power dissipation for various operating modes. Usage Typical power dissipation values depend on the location within the host, amount of data transferred, etc.

Specific areas requiring heat dissipation are shown in Figure 8-4:

Transmitter Top face of module near RF connectors. Likely to be the hottest area. Baseband 1 Top face of module, below the transmitter. Receiver Bottom face of module, behind the transmitter. Baseband 2 Bottom face of module, behind Baseband 1.

To enhance heat dissipation:

Maximize airflow over / around the module.

Locate the module away from other hot components. If possible, use the mounting holes to attach (ground) the device to the main PCB ground or a metal chassis. Note: Adequate dissipation of heat is necessary to ensure that the module functions properly, and to comply with the thermal requirements in [11] PCI Express Mini Card Electromechanical Specification Revision 1.2. Caution: Thermal putty is not recommended incorrect application of the material could require exessive pressure to be applied when seating the board, resulting in damage to the board. 56 Proprietary and Confidential - Contents subject to change 2400074 Mechanical and Environmental Specifications Module integration testing When testing your integration design:

Upon commercial release, the following regulatory approvals will have been attained:

FCC IC (Industry Canada) Upon commercial release, the following industry approvals will have been obtained:

GCF-CC (may be obtained upon customer request) Additional approvals may be obtained upon customer request contact your Sierra Wireless account representative for details. Additional testing and certification may be required for the end product with an embedded MC7750 modem and are the responsibility of the OEM. Sierra Wireless offers professional services-based assistance to OEMs with the testing and certification process, if required. Important notice Because of the nature of wireless communications, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost. Although significant delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used in a normal manner with a well-

constructed network, the Sierra Wireless modem should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless and its affiliates accept no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or receive such data. Safety and hazards Do not operate your MC7750 modem:

Where explosive atmospheres may be present including In areas where blasting is in progress

refuelling points, fuel depots, and chemical plants Near medical equipment, life support equipment, or any equipment which may be susceptible to any form of radio inter-

ference. In such areas, the MC7750 modem MUST BE Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 59 Product Technical Specification & Customer Design Guidelines POWERED OFF. Otherwise, the MC7750 modem can transmit signals that could interfere with this equipment. In an aircraft, the MC7750 modem MUST BE POWERED OFF. Otherwise, the MC7750 modem can transmit signals that could interfere with various onboard systems and may be dangerous to the operation of the aircraft or disrupt the cellular network. Use of a cellular phone in an aircraft is illegal in some jurisdictions. Failure to observe this instruction may lead to suspension or denial of cellular telephone services to the offender, or legal action or both. Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. The MC7750 modem may be used normally at this time. Important compliance information for North American users The MC7750 modem has been granted modular approval for mobile applications. Integrators may use the modem in their final products without additional FCC / IC

(Industry Canada) certification if they meet the following conditions. Otherwise, additional FCC / IC approvals must be obtained.

Although the MC7750 modem has been granted module approval, there are many conditions attached to this approval; final host integration will likely require additional testing. Detailed guidelines are described in OEM device classification process on page 61 to assist OEM module integrators in deter-

mining the extent of additional testing necessary to comply with FCC require-

ments. The end product with an embedded MC7750 modem must be evaluated for simultaneous transmission requirements. See Simultaneous transmission evaluation on page 62 for details. A user manual with the end product must clearly indicate the operating requirements and conditions that must be observed to ensure compliance with current FCC / IC RF exposure guidelines. See OEM product instruction manual content on page 63 for details. To comply with FCC / IC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not exceed:

Part 22 (Cellular): 7.3 dBi Part 24 (PCS): 3 dBi Part 27 (Band 13): 9 dBi A label must be affixed to the outside of the end product into which the MC7750 modem is incorporated, with a statement similar to the following:

This device contains FCC ID: N7NMC7750 This equipment contains equipment certified under IC: 2417C-MC7750

The end product with an embedded MC7750 modem may also need to pass the FCC Part 15 unintentional emission testing requirements and be properly authorized per FCC Part 15. 60 Proprietary and Confidential - Contents subject to change 2400074 Regulatory and Industry Approvals Note: If this module is intended for use in a portable device, you are responsible for separate approval to satisfy the SAR requirements of FCC Part 2.1093 and IC RSS-102. OEM integration Application of regulatory guidelines Because near-body devices (handhelds, laptops, tablets, scanners, etc.) vary widely in design features, physical configurations, and use-models, module integrators shall follow the guidelines below regarding device classification and simultaneous transmission, and seek guidance from their preferred regulatory test lab to determine how regulatory guidelines will impact the device compliance. Proactive management of the regulatory process will minimize unexpected schedule delays and costs due to unplanned testing activities. Device classifications The OEM integrator must determine the minimum distance required between their device and the users body. The FCC provides device classification definitions to assist in making the correct determination. Note that these classifications are guidelines only; strict adherence to a device classification may not satisfy the regulatory requirement as near-body device design details may vary widely. FCC definitions:

Portable: (2.1093) A portable device is defined as a transmitting device designed to be used so that the radiating structure(s) of the device is / are within 20 centimeters of the body of the user. Mobile: (2.1091) (b) A mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitters radiating structure(s) and the body of the user or nearby persons. Per 2.1091d(d)(4) In some cases (for example, modular or desktop transmitters), the potential conditions of use of a device may not allow easy classification of that device as either Mobile or Portable. In these cases, applicants are responsible for determining minimum distances for compliance for the intended use and installation of the device based on evaluation of either specific absorption rate

(SAR), field strength, or power density, whichever is most appropriate. OEM device classification process The primary factor in determining whether a device will be classified as a Portable product or as a Mobile product is antenna separation distance (body to radiating antenna element). Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 61 Product Technical Specification & Customer Design Guidelines The review process between the OEM module integrator and the preferred regulatory test lab is a crucial step in determining the appropriate device classification, as it is impractical for Sierra Wireless to define all possible combinations of design features, antennas, physical configurations, and use-

models. 1. Perform a device review with the preferred regulatory test lab to confirm device classification. 2. Determine the Certification type (Standalone or C2PC from an existing 3. 4. Modular Grant). If the device classification is:

Portable: Preferred regulatory test lab to determine if a PBA or KDB is required. Mobile: Preferred regulatory test lab to determine if a PBA is required.

(Note: A PBA or KDB will likely be required for new technologies such as LTE or WiMAX.) If the device classification is Mobile, confirm the antenna does not violate the Gain Limits specific to the module grant as specified in Important compliance information for North American users on page 60. 5. Outline and execute a test plan with the preferred regulatory test lab. Testing is likely to include some or all of Parts 15, 22, 24, 27, and either SAR

(for Portable devices) or MPE (for Mobile devices). 6. Follow product labeling requirements as described in Important compliance 7. information for North American users on page 60. (Ref 2.925) Include the OEM product instruction manual content on page 63 boilerplate text within the host products instruction manual. Simultaneous transmission evaluation The MC7750 modem has not been evaluated or approved for simultaneous transmission as the number of possible multi-transmission scenarios for this device is large. Any simultaneous transmission condition established through module integration into a customer-specific product must be evaluated per the requirements in KDB447498D01(8) and KDB616217D01,D03 (for laptop, notebook, netbook, and tablet applications). These requirements include, but are not limited to:

Transmitters and modules certified for mobile or portable exposure conditions can be incorporated in mobile host devices without further testing or certifi-

cation when:

The closest separation among all simultaneous transmitting antennas is 20 cm, or Antenna separation distance and MPE compliance requirements for All simultaneous transmitting antennas have been specified in the application filing of at least one of the certified transmitters within the host device. In addition, when transmitters certified for portable use are incorporated in a mobile host device, the antenna(s) must be 5 cm from all other simulta-

neous transmitting antennas. 62 Proprietary and Confidential - Contents subject to change 2400074 Regulatory and Industry Approvals

a. These worst-case VSWR figures for the transmitter bands may not guarantee RSE levels to be within regulatory limits. The device alone meets all regulatory emissions limits when tested into a cabled (conducted) 50 ohm system. With antenna designs with up to 2.5:1 VSWR or worse, the radiated emissions could exceed limits. The antenna system may need to be tuned in order to meet the RSE limits as the complex match between the module and antenna can cause unwanted levels of emissions. Tuning may include antenna pattern changes, pahse/delay adjustment, passive component matching. Examples of the application test limits would be included in FCC Part 22 and Part 24, test case 12.2.1 for GSM (3GPP TS 51.010), and test case 4.2.2 for WCDMA (ETSI EN 301 511). b.

This includes items relating to the power interface, RF integration, thermal considerations, cabling issues, and so on. Note: This is NOT an exhaustive list of design considerations. It is expected that you will employ good design practices and engineering principles in your integration. Table B-1: Hardware integration design considerations Suggestion Section where discussed Component placement Protect the SIM socket so the SIM cannot be removed while the host is powered up. If an ESD suppressor is not used, allow space on the SIM connector for series resistors in layout. (Up to 100 may be used depending on ESD testing requirements). SIM implementation on page 32 SIM implementation on page 32 Minimize RF cable losses as these affect performance values listed in product specification documents. RF connections on page 37 Antennas Match the module / antenna coax connections to 50 mismatched antenna impedance and cable loss negatively affect RF performance. RF connections on page 37 If installing CDMA and UMTS modules in the same device, consider using separate antennas for maximum performance. Antenna and cabling on page 38 Power Make sure the power supply can handle the maximum current specified for the module type. Limit the total impedance of VCC and GND connections to the SIM at the connector to less than 1 (including any trace impedance and lumped element components inductors, filters, etc.). All other lines must have a trace impedance less than 2 . Power consumption on page 45 SIM implementation on page 32 Decouple the VCC line close to the SIM socket. The longer the trace length (impedance) from socket to module, the greater the capacitance requirement to meet compliance tests.

SIM implementation on page 32 To minimize noise leakage, establish a very good ground connection between the module and host. Ground connection on page 39 Route cables away from noise sources (for example, power supplies, LCD assemblies, etc.). Methods to mitigate decreased Rx performance on page 40 Shield high RF-emitting components of the host device (for example, main processor, parallel bus, etc.). Methods to mitigate decreased Rx performance on page 40 Use discrete filtering on low frequency lines to filter out unwanted high-order harmonic energy.

Use appropriate techniques to reduce module temperatures (for example, airflow, heat sinks, heat-relief tape, module placement, etc.). Host / Modem communication Make sure the host USB driver supports remote wakeup, resume, and suspend operations, and serial port emulation. When no valid data is being sent, do not send SOF tokens from the host (causes unnecessary power consumption). Thermal considerations on page 56 Thermal considerations on page 56

Developers of OEM devices integrating Sierra Wireless AirPrime embedded modules should include a series of test phases in their manufacturing process to make sure that their devices work properly with the embedded modules. Suggested phases include:

Acceptance testing Testing of modules when they are received from Sierra Wireless Certification testing Testing of completed devices to obtain required certifications before beginning mass production Production testing Testing of completed devices with the modules embedded

Quality assurance testing Post-production AT command entry timing requirement Some AT commands require time to process before additional commands are entered. For example, the modem will return OK when it receives AT!DAFTMACT. However, if AT!DASBAND is received too soon after this, the modem will return an error. When building automated test scripts, ensure that sufficient delays are embedded where necessary to avoid these errors. Acceptance testing Note: Acceptance testing is typically performed for each shipment received. When you receive a shipment from Sierra Wireless, you should make sure it is suitable before beginning production. From a random sampling of units, test that:

Units are operational Units are loaded with the correct firmware version Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 71 Product Technical Specification & Customer Design Guidelines Note: You can perform these tests using appro-

priate AT commands. Acceptance test requirements To perform the suggested tests, you require a test system in which to temporarily install the module, and you must be able to observe the test devices LED indicator. Acceptance test procedure The following is a suggested acceptance testing procedure using Sierra Wireless Watcher software:

Test 1: Check power-up and initialization 1. After installing the module, start the test system. 2. Launch Watcher. 3. Check the LED If the LED is off, there is a problem with the module or with the connection to the LED. Test 2: Check version numbers 1. From Watcher, select Help > About. 2. Verify that the firmware version in the About window is correct. 3. Close the About window. If the module fails either of these tests, or is not recognized by Watcher:

1. Replace the module with one that is known to work correctly and repeat the tests. If the tests are successful, reinstall the original module and repeat the tests. 2. If the module still does not work correctly, contact your account manager. Certification testing Note: Typically, certification testing of your device with the integrated module is required one time only. The AirPrime embedded module has been certified as described in Regulatory and Industry Approvals on page 59. When you produce a host device with a Sierra Wireless AirPrime embedded module, you must obtain certifications for the final product from appropriate regulatory bodies in the jurisdictions where it will be distributed. The following are some of the regulatory bodies from which you may require certification it is your responsibility to make sure that you obtain all necessary certifications for your product from these or other groups:

Make sure that the tests you perform exercise functionality to the degree that your situation requires. Use an appropriate test station for your testing environment (see Acceptance test requirements on page 72 for suggestions) and use AT commands to control the integrated module. Note: Your test location must be protected from ESD to avoid interference with the module and antenna(s), assuming that your test computer is in a disassembled state. Also, consider using an RF shielding box local government regulations may prohibit unauthorized transmissions.

Testing CDMA RF Receive path Note: This procedure segment is performed in Step 13 of the Production test procedure on page 74. To test the DUTs receive path:

1. Set up the signal generator:

Note: This procedure describes steps using the Agilent 8648C signal generator the Rohde &

Schwarz SML03 is shown for reference only. Note: This example setup uses a 200 kHz offset from band center for testing using a continuous wave you can use any appro-

priate baseband frequency offset (for example, 100 kHz, 300 kHz, etc.). If using a modulated signal, set the frequency to band center with no offset. a. Press the Frequency button to set the frequency to 1960.200 MHz for PCS band, Channel 600, or 881.720 MHz for Cellular band, Channel 384 b. Press the Amplitude button to set the amplitude to -55.0 dBm. c. Press the RF ON / OFF button to enable or disable the RF port of the signal generator. 2. Read back the power level from the main receiver:

a. AT!ENTERCND (Unlock the extended AT command set.) b. AT!DAFTMACT (Enter test mode.) c. AT!CHAN=600,1 (PCS band, channel 600) or AT!CHAN=384,0 (Cellular band, channel 384) d. AT!RX=1 (Turn on the main receiver.) e. AT!RXAGC? (Read back the power level, in dBm, from the main receiver.) Response examples:

AT!RX2=1 (Turn on diversity receiver.) g. AT!RX2AGC? (Read back the power level, in dBm, from the diversity receiver.) Response examples:

RX2AGC = 0xFFFFFF76 = -84 dBm (Signal generators RF port is OFF) RX2AGC = 0xFFFFFFC6 = -69 dBm typical (Signal generators RF port is ON) h. AT!RX=0 (Turn off main receiver.) i. AT!RX2=0 (Turn off diversity receiver.) 3. Test limits Run ten or more good DUTs through this test procedure to obtain a nominal received power value. Apply a tolerance of 5 to 6 dB to each measurement (assuming a good setup design). Make sure the measurement is made at a high enough level that it is not influenced by DUT-generated and ambient noise. The Signal Generator power level should be at least -50 dBm. Monitor these limits during mass-production ramp-up to determine if further adjustments are needed. Note: The value measured by the DUT depends on the test setup and DUT design. Host RF cabling loss, antenna efficiency and pattern, test antenna efficiency and pattern, and choice of shield box all significantly influence the measurement. Note: When doing the same test over the air in an RF chamber, values are likely to be significantly lower. LTE RF receive path test Note: This procedure segment is performed in Step 13 of the Production test procedure on page 74. Table C-1 contains parameters used in the suggested test procedure that follows.

All values offset from actual center channel by +2 MHz b. Channel values shown are at the center of the corresponding bands. To test the DUTs receive path (or diversity path, while connected to the diversity antenna):

1. Set up the signal generator:

Note: This procedure describes steps using the Agilent 8648C signal generator the Rohde &

Schwarz SML03 is shown for reference only. a. Set the amplitude to -70 dBm b. Set the frequency for the band being tested. See Table C-1 for frequency values. 2. Set up the DUT:

a. AT!ENTERCND (Unlock extended AT command set.) b. AT!DAFTMACT (Put modem into factory test mode.) c. AT!DASBAND=<band> (Set frequency band.) See Table C-1 on page 78 for <band> values d. AT!DASCHAN=<channel> (Set modem channel) See Table C-1 on page 78 for <channel> values e. AT!DALGAVGAGC=<channel>,0 (Get averaged Rx AGC) See Table C-1 on page 78 for <channel> values 3. Test limits Run ten or more good DUTs through this test procedure to obtain a nominal received power value. Apply a tolerance of 5 to 6 dB to each measurement (assuming a good setup design). Make sure the measurement is made at a high enough level that it is not influenced by DUT-generated and ambient noise. The Signal Generator power level can be adjusted and new limits found if the radiated test needs greater signal strength. Monitor these limits during mass-production ramp-up to determine if further adjustments are needed. Rev 4 Sep.11 Proprietary and Confidential - Contents subject to change 79 Product Technical Specification & Customer Design Guidelines Note: The value measured from the DUT is significantly influenced by the test setup and DUT design (host RF cabling loss, antenna efficiency and pattern, test antenna efficiency and pattern, and choice of shield box). GPS standalone connector test GPS testing should be done on devices that support a dedicated GPS connector. If the MC7750 supports a dedicated GPS connector/path (that is, not shared with the diversity connector), then GPS testing may be done by characterizing some known-good MC devices and checking for carrier to noise levels. To test the GPS path:

1. Inject a carrier signal at -110dBm, frequency 1575.52 MHz into the GPS Rx path. (Note that this is 100kHz higher than the actual GPS frequency.) 2. Test the signal carrier-to-noise level at the GPS receiver:

a. AT!ENTERCND (Unlock extended AT command set.) b. AT!DAFTMACT (Put modem into factory test mode.) c. AT!DACGPSTESTMODE=1 (Start CGPS diagnostic task.) d. AT!DACGPSSTANDALONE=1 (Enter standalone RF mode.) e. AT!DACGPSMASKON (Enable log mask.) f. AT!DACGPSCTON (Return signal-to-noise and frequency measurements.) g. Repeat AT!DACGPSCTON five to ten times to ensure the measurements are repeatable and stable. 3. Leave the RF connection to the Mini Card device intact, and turn off the signal generator. 4. Take several more !DACGPSCTON readings. This will demonstrate a 'bad'

signal in order to set limits for testing, if needed. This frequency offset should fall outside of the guidelines in the note below, which indicates that the CtoN result is invalid.

(Optional) Turn the signal generator on again, and reduce the level to -

120dBm. Take more !DACGPSCTON readings and use these as a reference for what a marginal / poor signal would be. 5. Note: The response to AT!DACGPSCTON for a good connection should show CtoN within 58 +/- 5dB and Freq (frequency offset) within 100000 Hz +/- 5000 Hz . Quality assurance testing Note: QA is an ongoing process based on random samples from a finished batch of devices. The quality assurance tests that you perform on your finished products should be designed to verify the performance and quality of your devices. The following are some testing suggestions that can confirm that the antenna is interfaced properly, and that the RF module is calibrated and performs to specifications:

Module registration on cellular networks 80 Proprietary and Confidential - Contents subject to change 2400074 Testing Power consumption

Originate and terminate data and voice (if applicable) calls

Cell hand-off Transmitter and receiver tests FER (Frame Error Rate) as an indicator of receiver sensitivity / performance Channel and average power measurements to verify that the device is trans-

mitting within product specifications RF sensitivity tests CDMA:

FER testing Test receiver sensitivity for conditions of minimum cell power.

FER can be measured for the specified receiver sensitivity of -104 dBm. The objective of this test is to determine if the FER measured is within the acceptable limits for the specified receiver sensitivity of the module. Unlike the FER tests performed during production testing, this test determines the receiver performance without the influence of the noise factor (AWGN), but with extremely low cell power. The reported FER and the confidence level must be <1% and >95% respectively for the test to be considered a pass. Suggested testing equipment To perform production and post-production tests, you will require appropriate testing equipment. A test computer can be used to coordinate testing between the integrated module (on the development kit or host) and the measurement equipment, usually with GPIB connections. The suggested setup includes a power meter to test RF output power and a signal generator to evaluate the receiver. Testing assistance provided by Sierra Wireless Extended AT commands have been implemented to assist with performing FTA GCF tests and portions of CE Mark tests requiring radio module access.
