Attachment to Resolution 303 from July 2, 2002. Updated on November 22, 2012. Requirements for Exposure to Radio Waves LOC8 includes a radio transmitter and receiver. It is designed and manufactured not to exceed the emission limits for exposure to radio frequency (RF) energy set by the Federal Communications Commission (FCC) of the U.S. Government. These limits are part of comprehensive guidelines and establish permitted levels of RF energy for standards that were developed by independent scientific organizations through periodic and thorough evaluation of scientific studies. The standards include a substantial safety margin designed to assure the safety of all persons, regardless of age and health. The exposure standard for wireless mobile phones employs a unit of measurement know as the Specific Absorption Rate (SAR). The SAR limit set by the FCC is 1.6 W/

kg.1 Tests for SAR are conducted using standard operating positions reviewed by the FCC with the phone transmitting at its highest certified power level in all tested frequency bands. Although the SAR is determined at the highest certified power level, the actual SAR level of the phone while operating can be well below the maximum value. This is because the phone is designed to operate at multiple power levels so as to use only the power required to reach the network. In general, the closer you are to a wireless base station antenna, the lower the power output. Before a phone model is available for sale to the public, it must be tested and certified to the FCC that it does not exceed the limit established by the government-adopted 1. In the United States and Canada, the SAR limit for mobile phones used by the public is 1.6 watts/kg

(W/kg) averaged over one gram of tissue. The standard incorporates a substantial margin of safety for the public and to account for any variations in measurements. 8-90-00160-0, Revision 1 2014 BI Incorporated BI Proprietary & Confidential vii Preface LOC8 User Guide requirement for safe exposure. The tests are performed in positions and locations (e.g., at the ear and worn on the body) as required by the FCC for each model. While there may be differences between the SAR levels of various phones and at various positions, they all meet the government requirement for safe exposure. Additional information on Specific Absorption Rates (SAR) can be found on the Cellular Telecommunications Industry Association (CTIA) website at http://

www.ctia.org. Electromagnetic Interference/Compatibility Nearly every electronic device is susceptible to electromagnetic interference (EMI) if inadequately shielded, designed or otherwise configured for electromagnetic compatibility. Facilities To avoid electromagnetic interference and/or compatibility conflicts, obey all facility posted notices about cellular phones. Hospitals or health care facilities may be using equipment that is sensitive to external RF energy. Aircraft Per FAA regulations cellular phones should be turned off when on board an aircraft. Any use of a radio product must be in accordance with applicable regulations per airline crew instructions. Medical Devices If a person using the LOC8 system also uses any personal medical devices (i.e. pacemaker, hearing aid, etc.), consult the manufacturer of the personal medical device to determine if it is adequately shielded from RF energy. A physician may be able to assist in obtaining this information. Operational Warnings There are certain areas where you want to avoid operation of any radio product. Potentially Explosive Atmospheres Turn off any radio product prior to entering any area with a potentially explosive atmosphere unless it is a radio product type especially qualified for use as Intrinsically Safe (for example, Factory Mutual, CSA, or UL-approved). Do not remove, install, or charge batteries in such areas. Sparks in a potentially explosive atmosphere can cause an explosion or fire resulting in bodily injury or even death. NOTE: The areas with potentially explosive atmospheres referred to above include fueling areas, such as below decks on boats, fuel or chemical transfer or storage facilities, areas where the air contains chemicals or particles, such as grain, dust or metal powders, and any other area where viii BI Proprietary & Confidential 2014 BI Incorporated 8-90-00160-0, Revision 1 LOC8 User Guide Preface you would normally be advised to turn off your vehicle engine. Areas with potentially explosive atmospheres are often but not always posted. Blasting Caps and Areas To avoid possible interference with blasting operations, turn off radio products when near electrical blasting caps, in a blasting area, or in areas posted: Turn off two-way radio. Obey all signs and instructions. 8-90-00160-0, Revision 1 2014 BI Incorporated BI Proprietary & Confidential ix

CN pins support pull-up, pull-down and GPIO notifications Bluegiga Technologies Oy Page 9 of 41 3 3.1 Power control Power supply requirements WF121 is designed to operate with a 3.3V nominal input voltage supplied to two module pads. The VDD_3.3V pad can be fed with a voltage between 2.3V and 3.6V and is used to power the internal microcontroller. The VDD_PA pad can be supplied with a voltage between 2.7V and 4.8V and supplies the RF power amplifier and the internal switch-mode converter powering the WiFi digital core. In lithium battery powered applications, VDD_PA can be connected directly to the battery, while a regulator is needed to supply the VDD_3.3V with a lower voltage, as needed by the design. The VDD_PA supply should be capable of providing at least 350mA, though the average consumption of the module will be much less than that. The VDD_3.3V supply will draw a peak current of less than 100mA, not including current drawn from the GPIO pins. The PA supply should preferably be bypassed with a 10 to 100F capacitor to smooth out the current spikes drawn by the Wi-Fi power amplifier. External high frequency bypassing is not needed, the module contains the needed supply filtering capacitors. While the Wi-Fi power saving modes reduce the idle consumption to very low levels, it may in some applications be useful to reduce the consumption even further. For this purpose, the Wi-Fi part of the module can be fully shut down internally by disabling the internal switch mode converter to minimize power consumption, though restarting it requires a new WiFi core power-up initialization. This will usually take several seconds, but in applications where a connection is required only once a few minutes or this might not be an issue while the reduced consumption can be very valuable. The WF121 module automatically applies various power saving modes during operation to minimize average power consumption. 3.2 Reset WF121 can be reset by the MCLR-pin (active low), system power up, the internal brown-out detector or the internal watchdog timer. Bluegiga Technologies Oy Page 10 of 41 4 Microcontroller WF121 contains a Microchip PIC32-series microcontroller with a MIPS M4K core. At a maximum clock frequency of 80 MHz the core can reach a performance of 125 DMIPS while keeping low power consumption. The microcontroller used in WF121 contains 512kB of Flash memory and 128kB of SRAM. Most peripheral features are directly provided by the microcontroller and for low level information and detailed descriptions please refer to the material and datasheets of the PIC32MX695H. Bluegiga Technologies Oy Page 11 of 41 Interfaces 5 5.1 General Purpose I/O pins To see which GPIOs are multiplexed with which features, please refer to Table 2. WF121 contains a number of pads that can be configured to be used as general purpose digital IOs, analog inputs or for various built-in functions. Provided functions include a Full Speed USB-OTG port, three I2C-ports, two SPI-ports, two to four UARTs, Ethernet MAC with RMII connection and various timer functions. Some of the pads are 5V tolerant. All GPIO pads can drive currents of up to +/- 25 mA. Four pins are available for implementing a coexistence scheme with a Bluetooth device. The exact order and function as well as the coexistence system desired is software configurable, with the default pad bindings shown in Table 3 for a Unity-3e+ coexistence scheme. If the pads are bound to WiFi chip pins, the CPU pins associated with the pads must be set to inputs. 5.2 Serial ports Pad number UART 1 UART 2 UART 4 UART 5 17 21 29 32 35 36 44 47 TX RX CTS RTS CTS RTS RX TX RX TX Table 3: Serial port pads RX TX Two UARTs are provided with RTS/CTS-handshaking.

This is meant for RF calibration and testing during module production and product certification measurements. These should in most applications be left unconnected, but should be taken into account when doing the application board layout. Avoid placing vias or signals without a solder mask under these pads. 5.11 Bluetooth co-existence Bluetooth coexistence systems allow co-located WiFi and Bluetooth devices to be aware of each other and to avoid simultaneous transfers that would degrade link performance. There are many ways of implementing such connections, from host driver negotiated channel and time sharing, to hardware signalling between the two devices. WF121 supports a number of different coexistence schemes with up to 4 control lines for hardware communication between the two devices. WiFi and Bluetooth may also use separate antennas, or share a single antenna through a switch and/or a coupler. With a shared antenna, usually two additional signals are needed to control the front end switch. WF121 contains an internal switch for separating WiFi and Bluetooth transmissions as well as a shared low noise amplifier that allows both WiFi and Bluetooth to receive simultaneously using the same amplifier. For use with CSR-based Bluetooth (BC4 to BC6 with firmware version 21 or later, BC7 and onwards with all versions), Unity-3e+ is recommended as the coexistence scheme. Unity-3e is an enhanced version of the 3-

wire Unity-3 scheme that uses tighter timings and uses the three control lines also for antenna switch control, removing the need for the two separate switch control lines which with the limited number of coexistence capable signals in WF121 would limit the supported coexistence schemes to just 2-wire schemes. Unity-3e+, or Unity-3e with Unity+ adds an additional BT_PERIODIC signal to communicate the need for a periodic transmission from the Bluetooth to the WiFi, allowing a guaranteed low-latency throughput for certain Bluetooth applications despite high WiFi usage. This allows reliable audio connections that would otherwise suffer from the WiFis higher priority.

coexistence schemes are supported and the associated signals can be assigned to the GPIO pads. In default mode these pins are tied to CPU GPIO functions. Antenna sharing is possible with 2-wire, Unity-2 and Unity-

3e/3e+ schemes. For more detailed information about implementing co-existence, see WF111 datasheet. 5.12 CPU Clock Pad number Function Description 30 31 OSC1 OSC2 External crystal input External crystal output Table 11: Clocking pads WF121 uses an internal 26 MHz crystal as the WiFi reference clock. The internal processor uses an integrated 8MHz RC oscillator and associated phase locked loop (PLL) to create its clock signals, but cannot share the internal crystal-stabilized WiFi clock. The internal CPU uses a PLL to create an 80MHz core clock. To use the USB functionality an external crystal and the associated capacitors must be implemented on the application board to provide a sufficiently accurate clock. A crystal with its associated capacitors can be connected to pads OSC1 and OSC2. If an external crystal is not needed, these pads are available for GPIO use. The USB clock synthesizer requires an internal reference frequency of 4MHz, so the crystal for USB use must be a multiple of 4MHz. An external oscillator can also be used to generate the CPU clock frequency. The voltage levels should be 3.3V logic level. Note: The present WF121 default firmware only supports 8MHz crystals or oscillators. The internal clock divider generating the reference frequency for the internal PLLs cannot be changed by the firmware, and to support automatic switchover between the internal RC oscillator and the external crystal, the default firmware needs an 8MHz clock. A custom firmware can be ordered with support for desired frequencies for easier crystal availability, for achieving desired UART baud rates and other applications. The Ethernet connection requires the external PHY to provide the 50MHz RMII reference clock. A crystal is not required for the module CPU for Ethernet operation. Bluegiga Technologies Oy Page 17 of 41 5.13 32.768 kHz External Reference Clock Pad number Function Description 35 36 SOSCI External 32.768 kHz crystal input SOSCO External 32.768 kHz crystal output Table 12: Slow clock The module contains integrated RC oscillators for sleep timing, one in the WiFi chipset, one in the CPU. The sleep clocks are used to periodically wake up the module while in power save modes. If more accurate timing is required, an external 32.768 kHz crystal and the associated capacitors can be placed to pads SOSCI and SOSCO. If an accurate sleep clock is not needed, the pads are available for GPIO use. An external oscillator can also be used to generate the sleep clock. The voltage levels should be 3.3V logic level. This low frequency clock is shared for both the CPU and the WiFi chipset. The default WiFi configuration uses only the internal oscillator, if support for a crystal stabilized WiFi sleep clock is required, please contact Bluegiga technical support. The Wi-Fi packet timing during active data transfer is derived from the internal 26MHz crystal and so is unaffected by the tolerances of the sleep clock.

Sufficient out-of-band blocking specification at the Low Noise Amplifier (LNA) input allows the receiver to be used in close proximity to GSM and WCDMA cellular phone transmitters without being desensitized. High-order baseband filters ensure good performance against in-band interference. 7.2 Wi-Fi Transmitter The transmitter features a direct IQ modulator. Digital baseband transmit circuitry provides the required spectral shaping and on-chip trims are used to reduce IQ modulator distortion. Transmitter gain can be controlled on a per-packet basis, allowing the optimization of the transmit power as a function of modulation scheme. The internal Power Amplifier (PA) has a maximum output power of +15dBm for IEEE 802.11g/n and +17dBm for IEEE 802.11b. The module internally compensates for PA gain and reference oscillator frequency drifts with varying temperature and supply voltage. 7.3 Antenna switch for Bluetooth coexistence WF121 supports sharing the integrated antenna or antenna connector with a Bluetooth device through the BT_RF pad. The module contains a bypass switch to route the Bluetooth signal directly to the antenna, and supports using the internal LNA for Bluetooth reception. The switch is controlled through the coexistence interface. Bluegiga Technologies Oy Page 20 of 41 Firmware 8 WF121 incorporates firmware which implements a full TCP/IP stack and Wi-Fi management. Exact features will depend on the firmware version used. Please see the documentation of the firmware for exact details. There are three main ways to use the module: Host controlled, script controlled or native application controlled. Host controlled means an external host is physically connected to the module and it sends simple commands to the module and one of several different host interfaces can be used. The module provides high level APIs for managing Wi-Fi as well as data connections. Bluegiga provides a thin API layer (BGLib) written in ANSI C for the host which can take care of creating and parsing the messages sent over the transport. For evaluation purposes GUI tools and a library for python are also provided. Host Application BGLib

(implements BGAPI) UART / USB / SPI BGAPI HTTP, FTP, SMTP etc. DHCP, TFTP, DNS etc. TCP UDP MLME IP 802.2 LLC 802.11 MAC 802.11 PHY Figure 3: WF121 software Data can be routed either through the API or through another physical interface. For example if the first UART is used for sending and receiving command events, a TCP/IP socket can be bound to the second UART and data written to the UART will seamlessly be passed to the TCP/IP socket. For information about the latest capabilities of the firmware, please refer to the WF121 API reference documentation accompanying it. The module can also be controlled by a script running on the module. This is especially useful for simple applications as it eliminates the need for a host controller and can drastically cut development time. In combination with a host it can also be used automate certain features such as the serial to TCP/IP functionality described above. Native application development is also possible as the stack will not require all of the available flash or memory. Please see the material accompanying the firmware release about more details of this option. Bluegiga Technologies Oy Page 21 of 41 Bluegiga Technologies Oy Page 22 of 41 9 Host interfaces 9.1 UART The module can be controlled over the UART interface. In order for the communication to be reliable, hardware flow control signals (RTS and CTS) must be present between the host and the module. When using high UART transfer speeds (between 1 and 20Mbps) an external crystal is required for sufficient clock accuracy. 9.2 USB When using the USB host interface, the module will appear as a USB CDC/ACM device enumerating as virtual COM port. The same protocol can be used as with the UART interface. 9.3 SPI Please refer to the Bluegiga WF121 API reference documentation supplied with the firmware regarding using SPI as the Host interface.

In other variants this pin is not connected. The antenna trace should be properly impedance controlled and kept short. Figure 6 shows a typical trace from the RF pin to a SMA connector. A transmission line impedance calculator, such as TX-Line made by AWR, can be used to approximate the dimensions for the 50 ohm transmission line. Figure 7 show cross sections of two 50 ohm transmission lines.

For an optimal performance of the antenna the layout should strictly follow the layout example shown in the above figures and the thickness of FR4 should be between 1 and 2 mm, preferably 1.6mm. Bluegiga Technologies Oy Page 31 of 41 Any dielectric material close to the antenna will change the resonant frequency and it is recommended not to place a plastic case or any other dielectric closer than 5 mm from the antenna. ANY metal in close proximity of the antenna will prevent the antenna from radiating freely. It is recommended not to place any metal or other conductive objects closer than 20 mm to the antenna except in the directions of the ground planes of the module itself. For optimal performance, place the antenna end of the module outside any metal surfaces and objects in the application, preferably on the device corner. The larger the angle in which no metallic object obstructs the antenna radiation, the better the antenna will work. The ANT pad on the antenna end of the WF121-A can be connected to the ground or left unsoldered. 13.4 Thermal considerations The WF121 module may at continuous full power transmit consume up to 1.3 W of DC power, most of which is drawn by the power amplifier. Most of this will be dissipated as heat. In any application where high ambient temperatures and constant transmissions for more than a few seconds can occur, it is important that a sufficient cooling surface is provided to dissipate the heat. The thermal pad in the bottom of the module must be connected to the application board ground planes by soldering. The application board should provide a number of vias under and around the pad to conduct the produced heat to the board ground planes, and preferably to a copper surface on the other side of the board in order to dissipate the heat into air. The module internal thermal resistance should in most cases be negligible compared to the thermal resistance from the module into air, and common equations for surface area required for cooling can be used to estimate the temperature rise of the module. Only copper planes on the circuit board surfaces with a solid thermal connection to the module ground pad will dissipate heat. For an application with high transmit duty cycles

(low bit rate, high throughput, long bursts or constant streaming) the maximum allowed ambient temperature should be reduced due to inherent heating of the module, especially with small fully plastic enclosed applications where heat transfer to ambient air is low due to low thermal conductivity of plastic. The module measured on the evaluation board exhibits a temperature rise of about 25oC above ambient temperature when continuously transmitting IEEE 802.11b at full power with minimal off-times and no collision detection (a worst case scenario regarding power dissipation). An insufficiently cooled module will rapidly heat beyond operating range in ambient room temperature. 13.5 EMC considerations Following recommendations helps to avoid EMC problems arising in the design. Note that each design is unique and the following list do not consider all basic design rules such as avoiding capacitive coupling between signal lines. Following list is aimed to avoid EMC problems caused by RF part of the module. Do not remove copper from the PCB more than needed. For proper operation the antenna requires a solid ground plane with as much surface area as possible. Use ground filling as much as possible. Connect all grounds together with multiple vias. Do not leave small floating unconnected copper areas or areas connected by just one via, these will act as additional antennas and raise the risk of unwanted radiations. Do not place a ground plane underneath the antenna. The grounding areas under the module should be designed as shown in Figure 4. When using overlapping ground areas use conductive vias separated max. 3 mm apart at the edge of the ground areas. This prevents RF from penetrating inside the PCB. Use ground vias extensively all over the PCB. All the traces in (and on) the PCB are potential antennas. Especially board edges should have grounds connected together at short intervals to avoid resonances. Avoid current loops. Keep the traces with sensitive, high current or fast signals short, and mind the return current path, having a short signal path is not much use if the associated ground path between Bluegiga Technologies Oy Page 32 of 41 the ends of the signal trace is long. Remember, ground is also a signal trace. The ground will conduct the same current as the signal path and at the same frequency, power and sensitivity. Split a ground plane ONLY if you know exactly what you are doing. Splitting the plane may cause more harm than good if applied incorrectly. The ground plane acts as a part of the antenna system. Insufficient ground planes or large separate sensitive signal ground planes will easily cause the coupled transmitted pulses to be AM-demodulated by semiconductor junctions around the board, degrading system performance. Overlapping GND layers without GND stitching vias Overlapping GND layers with GND stitching vias shielding the RF energy Figure 9: Use of stitching vias to avoid emissions from the edges of the PCB Bluegiga Technologies Oy Page 33 of 41 14 Soldering recommendations WF121 is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and particular type of solder paste used. Consult the datasheet of particular solder paste for profile configurations. Bluegiga Technologies will give following recommendations for soldering the module to ensure reliable solder joint and operation of the module after soldering. Since the profile used is process and layout dependent, the optimum profile should be studied case by case. Thus following recommendation should be taken as a starting point guide. Refer to technical documentations of particular solder paste for profile configurations Avoid using more than one flow. Reliability of the solder joint and self-alignment of the component are dependent on the solder volume. Minimum of 150m stencil thickness is recommended. Aperture size of the stencil should be 1:1 with the pad size. A low residue, no clean solder paste should be used due to low mounted height of the component. If the vias used on the application board have a diameter larger than 0.3mm, it is recommended to mask the via holes at the module side to prevent solder wicking through the via holes. Solders have a habit of filling holes and leaving voids in the thermal pad solder junction, as well as forming solder balls on the other side of the application board which can in some cases be problematic.

Antennas not included in this list or having a gain greater than 2.14 dB are strictly prohibited for use with this device. The required antenna impedance is 50 ohms. Antenna Type Dipole Qualified Antenna Types for WT121-E Maximum Gain 2.14 dBi Table 25: Qualified Antenna Types for WF121-E Any antenna that is of the same type and of equal or less directional gain as listed in table 29 can be used without a need for retesting. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. Using an antenna of a different type or gain more than 2.14 dBi will require additional testing for FCC, CE and IC.
