General 2.0 Product Overview The pX2 Gen2 is a high-performance embedded wireless data transceiver. Operating in the 2400 2483.5 MHz ISM band, this frequency-hopping spread-spectrum module is capable of providing reliable wireless data transfer between almost any type of equipment which uses an asynchronous serial interface. The small-size and superior RF performance of this module make it ideal for many applications. While a pair of pX2 Gen2 modules can link two terminal devices (point-

to-point operation); multiple modules can be used together to create a network of various topologies, including point-to-multipoint and repeater operation. Multiple independent networks can operate concurrently, so it is possible for unrelated communications to take place in the same or a nearby area without sacrificing privacy or reliability. 1.1 Features Key features of the pX2 Gen2 include:

transmission within a public, license-exempt band of the radio spectrum1 this means that it can be used without access fees

(such as those incurred by cellular airtime). a serial I/O data port with handshaking and hardware flow control, allowing the pX2 Gen2 to interface directly to any equipment with an asynchronous serial interface. ease of installation and use the pX2 Gen2 module uses a subset of standard AT style commands, very similar to those used by traditional telephone line modems. all units in a system are physically identical, and can be configured as a master, repeater or slave using the AT command set. No hardware modifications are required 128 sets of user-selectable pseudo-random hopping patterns, intelligently designed to offer the possibility of separately operating multiple networks while providing security, reliability and high tolerance to interference. encryption key with 65536 user-selectable values to maximize security and privacy of communications. 32-bit of CRC error detection and auto re-transmit to provide accuracy and reliability of data. 1 2400-2483.5 MHz, which is license-free within North America; may need to be factory-configured differently for some countries. 1 TDMA (time division multiple access) support, allowing multi-slave access in point-to-point mode. roaming ability, allowing repeaters and slaves to re-

synchronize with a new master if the synchronization pulse from the original master is lost. While the typical application for the pX2 Gen2 is to provide a short- to mid-

range wireless communications link between DTEs, it can be adapted to almost any situation where an asynchronous serial interface is used and data intercommunication is required. 2.1 Output Power Level The Output Power Level determines at what power the pX2 Gen2 transmits. The pX2 Gen2s sensitive receiver can operate with very low power levels, so it is recommended that the lowest power necessary is used; using excessive power contributes to unnecessary RF pollution. Ideally, you should test the communications performance between units starting from a low power level and working upward until the RSSI is sufficiently high and a reliable link is established. The conditions will vary widely between applications, the output power settings can be calculated based on following information. Equivalent Isotropically Radiated Power (EIRP) requirement by FCC Transmitter antenna gain Cable loss Regulations Power Setting = 36 Antenna Gain Cable Loss The power setting must be no more than the above calculation value. Any higher is a violation of FCC rules. See IMPORTANT warning below. Table 1 Output Power Power Setting

Installation 3.0 Overview The pX2 Gen2 complies with FCC part 15 at the modular level for operation in the license-free 2400-2483.5 MHz ISM band. This chapter provides guidelines for installing and deploying equipment which incorporates the pX2 Gen2 module. 3.1 Estimating the Gain Margin Successful communication between pX2 Gen2 modules is dependent on three main factors:

System Gain Path Loss Interference System gain is a calculation in dB describing the performance to be expected between a transmitter-receiver pair. The number can be calculated based on knowledge of the equipment being deployed. The following four factors make up a system gain calculation:

1. Transmitter power (user selectable) 2. Transmitter gain (transmitting antenna gain minus cabling loss between the transmitting antenna and the pX2 Gen2 module) 3. Receiver gain (Receiving antenna gain minus cabling loss between the receiving antenna and the module) 4. Receiver sensitivity (Specified as -108dBm on the pX2 Gen2 module) In the following illustration, the transmitting antenna has a gain of 6 dB, and the receiving antenna has a gain of 3 dB. The cable loss between the module and the antenna is 2 dB on both the transmitting and receiving side. Cable Loss = 2 dB Cable Loss = 2 dB Antenna Gain = 6 dB Antenna Gain = 3 dB Receiver Sensitivity =

-105 dBm Transmitter 30 dBm Output Power Chapter3 Installation 3 Figure 1 Gain Calculation The power level has been set to 30dBm (1W) on the transmitter, and the receiver sensitivity for the pX2 Gen2 is -108dBm. System gain would be calculated to be:

30 - 2 + 6 + 3 - 2 + 108 = 143 dB. Base Height (m) Mobile Height

(m) Distance (km) Figure 2 System Deploying When deploying your system, care must be taken to ensure the path loss

(reduction of signal strength from transmitter to receiver in dB) between equipment does not exceed the system gain (140 dB in the above example). It is recommended to design for a gain margin of at least 20 dB to ensure reliable communication. Gain margin is the difference between system gain and path loss. Referring to the same example, suppose the path loss is 100 dB, the gain margin would be 40 dB, which is more than adequate for reliable communication. Path loss is a very complicated calculation which mainly depends on the terrain profile, and the height of the antennas off the ground. The following table provides path loss numbers for varying antenna heights and antenna separation: These numbers are real averages taken from rural environments. They do not apply to urban, non-line-of-sight environments. Table 2 Path Loss Distance

This register provides the average signal strength in dBm. The minimum strength for communication is roughly -108dBm. For consistent reliable communication, you should try to deploy the equipment such that signal strength exceeds -95dBm. 3.2 Antennas and Cabling This section describes the recommended procedure for installing cabling and antennas for use with the pX2 Gen2 module. 3.2.1 Internal Cabling The most common method for installing the module is to run a cable from the modules UFL connector to a reverse TNC bulkhead connector on the chassis of the equipment as shown in Figure 3. This cable can be purchased from Microhard Systems. Reverse TNC Connector RG316 Cable with UFL connector and Reverse TNC bulkhead connector UFL connector 2 N E G 2 X P Figure 3 Suggested Internal Cabling Cable losses are negligible for the short piece used within the chassis. Additional losses up to 0.5 dB may be present in the MCX and Reverse TNC connections. 5 pX2 Gen2 Operating Manual 6 WARNING:

To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 25 cm (38cm collocated with LTE module) or more should be maintained between the antenna of this device and persons during device operation. To ensure compliance, operations at closer than this distance is not recommended. The antenna used for this transmitter must not be co-

located in conjunction with any other antenna or transmitter. WARNING:

Direct human contact with the antenna is potentially unhealthy when the pX2 Gen2 is generating RF energy. Always ensure that the pX2 Gen2 equipment is powered down during installation. 3.2.2 Installing External Cables, Antennas and Lightning Arrestors Never work on an antenna system when there is lightning in the area. Direct human contact with the antenna is potentially unhealthy when the pX2 Gen2 is generating RF energy. Always ensure that the pX2 Gen2 equipment is powered down during installation. At all times a distance of 23 cm must be maintained between the antenna and any person when the device is in operation. Surge Arrestors The most effective protection against lightning is to install two lightning

(surge) arrestors, one at the antenna, the other one at the interface with the equipment. The surge arrestor grounding system should be fully interconnected with the transmission tower and power grounding systems to form a single, fully integrated ground circuit. Typically, both ports on surge arrestors are N-female. External Filter Although the pX2 Gen2 is capable of filtering out RF noise in most environments, there are circumstances that require external filtering. Paging towers and cellular base stations in close proximity to the pX2 Gen2 antenna can desensitize the receiver. Microhard Systems external cavity filter eliminates this problem. The filter has two N-female ports and should be connected in line at the interface to the RF equipment. Weatherproofing Type N and RTNC connectors are not weatherproof. All connectors should be taped with rubber splicing tape (weatherproofing tape), and then coated with a sealant. WARNING:

Never work on an antenna system when there is lightning in the area. Cabling The following coax cables are recommended:

Table 3 Cable Loss Cable Loss (dB/100ft) 10.7 3.9 2.5 LMR 195 LMR 400 LMR 600 price;

Factors to take into consideration when choosing a cable are:

bend radius limitations (the lower performance cables generally can bend more sharply) performance requirements; and, distance between the equipment and the antenna. pX2 Gen2 Operating Manual WARNING:

MAXIMUM EIRP FCC and IC Regulations allow up to 36dBm effective isotropically radiated power

(EIRP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 36 dBm with respect to the isotropic radiator. WARNING:

The pX2 Gen2 can only be used with any antennas listed in Appendix A. WARNING:

Be careful with dBi vs dBd gains on antenna specifications. Antenna manufactures may not clearly indicate the gain on the antenna if it is dBd or dBi. Note 1dBd = 2.15dBi. When installing the cable, always begin fastening at the top near the antenna connector/surge arrestor. The cable must be supported at the top with a hose clamp or wrap lock, and at 5 ft intervals down the length of the tower. Over-tightening the fasteners will dent the cable and reduce performance. If properly grounded surge arrestors are not installed at both the top and the bottom of the cable, then the cable should be grounded to the tower at these locations using a cable grounding kit. If the tower is non-

conductive, then a separate conductor, physically separate from the cable, should be run down the tower. Antenna Before choosing an antenna, you should have some knowledge of the path loss and the topology of the equipment. If the equipment is in a fixed location and is to communicate with only one other unit also in a fixed location, then a Yagi antenna is suitable. Choose a Yagi with enough gain to ensure adequate gain margin. When deploying the Yagi, point the antenna towards the intended target, ensuring the antenna elements are perpendicular to the ground for vertical polarization. In applications where there are multiple units that you must communicate with or units, which are in motion, you may select an Omni-directional antenna with appropriate gain. See appendix A for a list of approved antennas that can be used with the pX2 Gen2 radio modem. If you require another type of antenna please contact Microhard Systems Inc. The pX2 Gen2 CANNOT be used with any antenna that does not appear in Appendix A. Microhard Systems Inc. can provide you with approved antennas to ensure FCC and Industry Canada compliance. FCC Regulations allow up to 36dBm effective isotropically radiated power (EIRP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 36dBm with respect to the isotropic radiator. EIRP is calculated as follows:

EIRP = Tx Power(dBm) - Cable/Connector Loss(dB) + Ant Gain(dBi) Antenna Gains must be in dBi when calculating the 36dBm EIRP limit. 1dBd = 2.15dBi Use the guidelines in the previous section for calculating cable and connector losses. If cabling and connector losses are 2 dB, then the maximum allowable gain of the antenna will be 8 dB.

Example 1) Max EIRP 36dBm Ant Gain dBi = 2dBi Example 2) Max EIRP 36dBm FCC and Industry Canada Regulations allow up to 36dBm effective isotropically radiated power (EIRP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain cannot exceed 36dBm with respect to the isotropic radiator. What is the maximum power the pX2 Gen2 can be set to comply with FCC and IC given the following equipment given a Rubber Ducky Ant Gain 2dBi and no cable or connectors in the system?

Max TX power = EIRP Ant Gain(dBi) + Cable/Connector loss (dB) Max TX power = 36dBm 2dBi + 0dB = 34dBm We can set the modem to the maximum power setting of 30dBm. What is the maximum power the pX2 Gen2 can be set to comply with FCC and IC given the following equipment given a Yagi Ant Gain 12dBd and cable and connector loss of 4.5 dB?

Max TX power = EIRP Ant Gain(dBi) + Cable/Connector loss (dB) Ant Gain dBi = Ant Gain dBd + 2.15 dB Yagi Gain (dBi) = 12 + 2.15 = 14.15dBi Max TX power = 36dBm 14.15dB + 4.5dB = 26.35dBm We must round down Hence Max TX power = 26dBm Example 3) What is the maximum power the pX2 Gen2 can be set to comply with FCC and IC given the following equipment given a Omni Ant Gain 6dBd and cable and connector loss of 2.5 dB?

Max EIRP 36dBm Max TX power = EIRP Ant Gain(dBi) + Cable/Connector loss (dB) Ant Gain dBi = Ant Gain dBd + 2.15 dB Omni Gain (dBi) = 6 + 2.15 = 8.15dBi Max TX power = 36dBm 8.15dB + 2.5dB = 30.35dBm Hence Max TX power = 30dBm 8 pX2 Gen2 Operating Manual A.

*=Plane-wave equivalent power density RF exposure compliance will need to be determined with respect to 1.1307(c) and (d) of the FCC rules. The emissions should be within the limits at 300kHz in Table 1 of 1.1310(use the 300kHz limits for 150kHz:614V/m,1.63A/m). Friis Formula Friis transmission formula: Pd = (Pout*G)/(4* Pi * R 2) Where Pd = power density in mW/cm2 Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = distance between observation point and center of the radiator in cm Pd id the limit of MPE, 1 mW/cm2 . If we know the maximum gain of the antenna and the total power input to the antenna, through the calculation, we will know the distance r where the MPE limit is reached. 3.1.2 Test Procedure Software provided by client enabled the EUT to transmit data at lowest, middle and highest channel individually.

<Collocated analysis>

General Note:

1. For colocation analysis, LTE Band 26 is chosen for summation due to the highest (power density/limit) among all WWAN wireless modes. 2. (Power Density / Limit): This is a summation of [(power density for each transmitter/antenna included in the simultaneous transmission)/ (corresponding MPE limit)], for WWAN + WLAN + Bluetooth 3. Considering the WWAN module collocation with the other transmitters of the EIRP performance listed in the table above, the aggregated (power density /limit) is smaller than 1, and MPE of 3 collocated transmitters is compliant.

Pursuant to Section 15.212(a)(1) of the FCC rules, the Applicant, request for single modular approval, compliance with the requirements are addressed below. Single Modular Approval Requirements Justification The modular transmitter has its own RF shielding The modular transmitter has buffered modulation/data inputs The modular transmitter has its own analog and digital power supply regulation. The radio and its associated antennas are provided with the special coupling antenna connectors The modular transmitter was tested in a stand-alone configuration

(i) The radio elements of the modular transmitter must have their own shielding. The physical crystal and tuning capacitors may be located external to the shielded radio elements.

(ii) The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with part 15 requirements under conditions of excessive data rates or over-modulation.

(iii) The modular transmitter must have its own power supply regulation.

(iv) The modular transmitter must comply with the antenna and transmission system requirements of 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a unique antenna coupler (at all connections between the module and the antenna, including the cable). The professional installation provision of 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section.

(v) The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with part 15 requirements. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see 15.27(a)). The length of these lines shall be the length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified and commercially available (see 15.31(i)).

The manual includes End Device labeling instructions.

(vi) The modular transmitter must be equipped with either a permanently affixed label or must be capable of electronically displaying its FCC identification number.

(A) If using a permanently affixed label, the modular transmitter must be labeled with its own FCC identification number, and, if the FCC identification number is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following:

Contains Transmitter Module FCC ID: XYZMODEL1 or Contains FCC ID: XYZMODEL1. Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization.

(B) If the modular transmitter uses an electronic display of the FCC identification number, the information must be readily accessible and visible on the modular transmitter or on the device in which it is installed. If the module is installed inside another device, then the outside of the device into which the module is installed must display a label referring to the enclosed module. This exterior label can use wording such as the following: Contains FCC certified transmitter module(s). Any similar wording that expresses the same meaning may be used. The user manual must include instructions on how to access the electronic display. A copy of these instructions must be included in the application for equipment authorization.

(vii) The modular transmitter must comply with any specific rules or operating requirements that ordinarily apply to a complete transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization.

(viii) The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. Hany Shenouda Director of Engineering Microhard Systems Inc. End-users must comply with the following instruction sated in the users manual:

Labeling requirement for equipment using this modular transmitter.
