General 2.0 Product Overview The MHX921 is a high-performance embedded wireless data transceiver. Operating in the 902 - 928 MHz ISM band, this a spread-spectrum module is capable of providing reliable wireless data transfer between almost any type of equipment. The small-size and superior RF performance of this module make it ideal for many applications. While a pair of MHX921 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 MHX921 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 MHX921 to interface directly to any equipment with an asynchronous serial interface.
ease of installation and use the MHX921 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. 1 902-928 MHz, which is license-free within North America; may need to be factory-
configured differently for some countries. MHX921 Operating Manual: Chapter2 General 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 MHX921 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 MHX921 transmits. The MHX921s 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. Transmitter antenna gain Cable loss Equivalent Isotropically Radiated Power (EIRP) requirement by FCC 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 Qualified and experienced personnel must carry out the installation, removal or maintenance of all antenna components. The MHX921 complies with FCC part 15 at the modular level for operation in the license-free 902-928 MHz ISM band. This chapter provides guidelines for installing and deploying equipment which incorporates the MHX921 module. 3.1 Estimating the Gain Margin Successful communication between MHX921 modules is dependent on three main factors:
System Gain Path Loss 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 Interference the transmitting antenna and the MHX921 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 MHX921 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 4 MHX921 Operating Manual: Chapter 3 Installation Figure 1 Gain Calculation The power level has been set to 30dBm (1W) on the transmitter, and the receiver sensitivity for the MHX921 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 MHX921 module. 3.2.1 Internal Cabling The most common method for installing the module is to run a cable from the modules MCX 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 MCX male connector and Reverse TNC bulkhead connector MCX female connector 1 2 9 X H M 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. 6 MHX921 Operating Manual: Glossary WARNING:
To satisfy FCC RF exposure requirements for mobile transmitting devices, a separation distance of 23 cm 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 MHX921 is generating RF energy. Always ensure that the MHX921 equipment is powered down during installation. WARNING:
Never work on an antenna system when there is lightning in the area. 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 MHX921 is generating RF energy. Always ensure that the MHX921 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 MHX921 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 MHX921 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. Cabling The following coax cables are recommended:
Table 3 Cable Loss Cable Loss (dB/100ft) LMR 195 LMR 400 LMR 600 10.7 3.9 2.5 Factors to take into consideration when choosing a cable are:
price;
bend radius limitations (the lower performance cables generally can bend more sharply) performance requirements; and, distance between the equipment and the antenna. MHX921 Operating Manual:Glossary 7 WARNING:
MAXIMUM EIRP FCC and IC Regulations allow up to 36dBm equivalent 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 MHX921 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 MHX921 radio modem. If you require another type of antenna please contact Microhard Systems Inc. The MHX921 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 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. 8 MHX921 Operating Manual: Glossary Examples:
FCC and Industry Canada Regulations allow up to 36dBm equivalent 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. Example 1) What is the maximum power the MHX921 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 EIRP 36dBm Max TX power = EIRP Ant Gain(dBi) + Cable/Connector loss (dB) Ant Gain dBi = 2dBi Max TX power = 36dBm 2dBi + 0dB = 34dBm We can set the modem to the maximum power setting of 30dBm. Example 2) What is the maximum power the MHX921 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 EIRP 36dBm 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 MHX921 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 MHX921 Operating Manual:Glossary 9 A.

FCC Inquiry 1) Operating/installation instructions indicate field-side, tower, etc installations and adjustment of transmitter output power depending upon antenna and cable selection. This is professional installation function, not OEM installation function. Per DA-00-1407, Modular Approval is not permitted for devices that require professional installation. See also TCB training documents about filing contents required for devices subject to professional installation. Response:
Any reference to filed-site or tower installations in the User Manual is to disavow any legal liability in a case whereby the OEM could sell this product to a client for tower installation. It is a statement of disclaimer. Any reference to anything other than this fact has been removed from the User/OEM Manual. (the manufacturer) FCC Inquiry 2) Filing has not appropriately address and documented FCC RF exposure compliance for all intended fix-mounted and mobile antennas and final installation conditions. Etc, etc, Response:
There was some confusion whereby the applicants office staff typed ERP rather than EIRP. These errors have been corrected and EIRP has replaced the erroneous ERP statement. The Manual supplied to the OEM contains page after page of calculations in order to configure the Module to meet the 36dBm EIRP restrictions. Actually, the last ten pages of the OEM Manual are dedicated to calculations to meet the antenna and power gain requirements. The wording is very detailed and written for even a layman to understand. For example, with the 14.2 dBi antenna described, no more than a 21.8 dBM is allowed as the maximum input limit. At 915MHz with a power input of 21.8 dBm (approximately 150 mW) the distance for RF compliance is 22.7 cm. Please examine the Grant Note: 23 cm is stated as the minimum distance for RF Safety Compliance. The Grant Note also states; Users and OEM integrators must be provided with antenna installations instructions and transmitter operating conditions for satisfying RF exposure compliance. Every antenna model listed and approved with this device is shown on Page 10 of the Manual. Page 7 describes cable loss. FCC Inquiry 3) Operating/installation instructions describe how to configure transmitter for a maximum output power of 36 dBm ERP = 3.98 W = 6.5 EIRP which exceeds the 15.247 limit i.e. 1 W Conducted output power into 6 dBi antenna = 4 W EIRP. Response:
FCC Part 15.247(b)(4) states: ..if transmitting antennas of directional gain greater than 6 dBi are used the peak output power for the intentional radiator shall be reduced..by the amount in dB that the directional gain of the antenna exceeds 6 dBi For example, if an antenna with a gain of 12 dBi is used, the antenna exceeds the standard 6 dBi antenna by 6 dBi. Therefore, one has to reduce the device power by 6dB. The Grant Certificate lists the maximum antenna conducted output power as 1 Watt conducted power. The statement on the Grant is very clear that the power is adjustable down to 0.1% of the maximum value. This equates to 0.001 Watt or 1 mW. 1 mW in terms of dBm is 0 dBm. The antenna with the highest gain is a yagi listed with a 12 dB gain. As you can see, 0dBm and 12dB are well within the defacto limit. (12 dB is equal to 14.1 dBi.) FCC Regulations allow up to 36dBm effective radiated power (EIRP). Therefore, the sum of the transmitted power (in dBm), the cabling loss and the antenna gain must not exceed 36dBm with respect to the isotropic radiator. The problem with this job was the typographical errors in the Manual supplied to the OEM. The errors were missed at the manufacturer, the Test Laboratory, and by me when I reviewed the items. It was a valid question from the FCC but in my opinion, these items could have been reviewed and corrected with an RT. Is dismissal appropriate?

(e) 1. Requirements for Modular Transmitters In order to be considered a transmitter module, the device must be complete RF transmitter, i.e., it must have its own reference oscillator (e.g., VCO), antenna, etc. The only connectors to the module, if any, may be power supply and modulation/data inputs Compliance with FCC RF Exposure requirements may, in some instances, limit the output power of a module and/or the final applications in which the approved module may be employed While the applicant for a device into which an authorized module is installed is not required to obtain a new authorization for the module, this does not preclude the possibility that some other form of authorization or testing may be required for the device (e.g., a WLAN into which the authorized module is installed still be authorized as PC peripheral, subject to the appropriate equipment authorization) In the case of a modular transceiver, the modular approval policy only applies to the transmitter portion of such devices. Pursuant to section 15.101(b), the receiver portion will either be subject to Verification, or it will not be subject to any authorization requirements (unless if is a Scanning Receiver, in which case it is also subject to Certification, pursuant to Section 15.101(a) The holder of the grant of equipment authorization (Grantee) of the module is responsible for the compliance of the module in its final configuration, provided that the OEM, integrator, and /or end user has complied with all of the instructions provided by the Grantee which indicate installation and/or operating conditions necessary for compliance. Manufacturers Clarification The transmitter is completed with its own reference oscillator, antenna. Only connectors provide are dc supply, data and rf ports are provided with the modular transmitter The radio is intended for use in all applications
(portable, mobile and base). It complies with SAR test with body tissue. The radio is intended for use with mobile or fixed base stations only. It complies with MPE per 2.1091 & 1.1307 The equipment under complies with FCC Part15, Subpart B, Class B Unintentional radiators The receiver operates in the band above 960 MHz;
therefore, the FCC authorization for the receiver is exempted. End-users must comply with the following instruction sated in the users manual:
Labeling requirement for equipment using this modular transmitter. RF Exposure Warning for compliance with FCC Rules 2.1091 and 1.1307 when the radio is used in a mobile or base system Requirements for Modular Transmitters The modulator transmitter must have its own RF shielding. This is intended to ensure that the module does not have to reply upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device Manufacturers Clarification The modular transmitter has its own RF shielding The modular transmitter has buffered modulation/data inputs The modular transmitter has its own power supply regulation. The radio and its associated antennas are provided with the special coupling antenna connectors (MCX or reversed SMA). The modular transmitter was tested in a stand-alone configuration 2. 3. 4. 5. into which the module is installed. Such coupling may result in noncompliant operation. 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 overmodulation. The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed. The modular transmitter must comply with the antenna requirements of section 15.203 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). Any antenna used with the module must be approved with the module, either at the time of initial authorization or through a Class II permissive change. The professional installation provision of Section 15.203 may not be applied to modules. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will marketed with the module (see Section 15.27(a)). The length of these lines shall be 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 or commercially available (See Section 15.31(I)).

PROVISIONS FOR FREQUENCY HOPPING SYSTEMS [ 15.247(a)(1)]
6.7.1. Limit 15.247(a)(1): Frequency hopping systems shall have hopping channel carrier frequencies separated by a minimum of 25 kHz or the 20 dB bandwidth of the hopping channel, whichever is greater. Alternatively, frequency hopping systems operating in the 2400-2483.5 MHz band may have hopping channel carrier frequencies that are separated by 25 kHz or two-thirds of the 20 dB bandwidth of the hopping channel, whichever is greater, provided the systems operate with an output power no greater than 125 mW. The system shall hop to channel frequencies that are selected at the system hopping rate from a pseudorandomly ordered list of hopping frequencies. Each frequency must be used equally on the average by each transmitter. The system receivers shall have input bandwidths that match the hopping channel bandwidths of their corresponding transmitters and shall shift frequencies in synchronization with the transmitted signals. 15.247(a)(1)(i): For frequency hopping systems operating in the 902928 MHz band: if the 20 dB bandwidth of the hopping channel is less than 250 kHz, the system shall use at least 50 hopping frequencies and the average time of occupancy on any frequency shall not be greater than 0.4 seconds within a 20 second period; if the 20 dB bandwidth of the hopping channel is 250 kHz or greater, the system shall use at least 25 hopping frequencies and the average time of occupancy on any frequency shall not be greater than 0.4 seconds within a 10 second period. The maximum allowed 20 dB bandwidth of the hopping channel is 500 kHz. 6.7.2. Method of Measurements FCC Public Notice DA 00-705 Carrier Frequency Separation:

The hopping function of the EUT is enabled. Use the spectrum analyzer setting as follows:
Span = 0 Hz centered on a hopping channel
RBW = 1 MHz
VBW > RBW
Sweep = as necessary to capture the entire dwell time per hopping channel
Detector = peak
Trace = max hold Page 15 FCC ID: NS906P21 If possible, use the marker-delta function to determine the dwell time. If this value varies with different modes of operation (e.g. date rate modulation format, etc.), repeat this test for each variation. The limit is specified in one of the subparagraphs of this Section. Submit this plot(s). An oscilloscope may be used instead of a spectrum analyzer. 20 dB Bandwidth:
Use the spectrum analyzer setting as follows:
Span = approximately 2 to 3 times the 20 dB bandwidth, centered on a hopping channel
RBW = 1% of the 20 dB bandwidth
VBW > RBW
Sweep = auto
Detector = peak
Trace = max hold
The transmitter shall be transmitting at its maximum data rate.
Allow the trace to stabilize.
Use the marker-to-peak function to set the marker to the peak of the emission.
Use the marker-delta function to measure 20 dB down on both sides of the emission.
The 20 dB BW is the delta reading in frequency between two markers. 6.7.3.

PEAK CONDUCTED OUTPUT POWER - DTS [ 15.247(b)(3)]
6.10.1. Limits 15.247(b)(3): For systems using digital modulation in the 902-928 MHz, 2400-2483.5 MHz, and 5725-5850 MHz bands: 1 Watt. As an alternative to a peak power measurement, compliance with the one Watt limit can be based on a measurement of the maximum conducted output power. Maximum Conducted Output Power is defined as the total transmit power delivered to all antennas and antenna elements averaged across all symbols in the signaling alphabet when the transmitter is operating at its maximum power control level. Power must be summed across all antennas and antenna elements. The average must not include any time intervals during which the transmitter is off or is transmitting at a reduced power level. If multiple modes of operation are possible (e.g., alternative modulation methods), the maximum conducted output power is the highest total transmit power occurring in any mode. 15.247(b)(4): The conducted output power limit specified in paragraph (b) of this section is based on the use of antennas with directional gains that do not exceed 6 dBi. Except as shown in paragraph (c) of this section, if transmitting antennas of directional gain greater than 6 dBi are used, the conducted output power from the intentional radiator shall be reduced below the stated values in paragraphs

A Pre-Amp and highpass filter are used for this measurement. For measurement below 1 GHz, set RBW = 100 KHz, VBW > 100 KHz, SWEEP=AUTO. For measurement above 1 GHz, set RBW = 1 MHz, VBW = 1 MHz (Peak) & VBW = 10 Hz (Average), SWEEP=AUTO. If the emission is pulsed, modified the unit for continuous operation, then use the settings above for measurements, then correct the reading by subtracting the peak-average correction factor derived from the appropriate duty cycle calculation.

RF EXPOSURE REQUIRMENTS [ 15.247(i), 1.1310 & 2.1091]
6.14.1. Limit
15.247(i): Systems operating under provisions of this section shall be operated in a manner that ensures Page 157 FCC ID: NS906P21 that the public is not exposed to radio frequency energy levels in excess of the Commissions guidelines. See 1.1307(b)(1).
1.1310:- The criteria listed in the following table shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in 1.1307(b). 6.14.2. Method of Measurements Refer to Sections 1.1310, 2.1091 and Public Notice DA 00-705 (March 30, 2000) Spread spectrum transmitters operating under section 15.247 are categorically from routine environmental evaluation to demonstrating RF exposure compliance with respect to MPE and/or SAR limits. These devices are not exempted from compliance (As indicated in Section 15.247(b)(4), these transmitters are required to operate in a manner that ensures that exposure to public users and nearby persons) does not exceed the Commissions RF exposure guidelines (see Section 1.1307 and 2.1093). Unless a device operates at substantially low power levels, with a low gain antenna(s), supporting information is generally needed to establish the various potential operating configurations and exposure conditions of a transmitter and its antenna(s) in order to determine compliance with the RF exposure guidelines. In order to demonstrate compliance with MPE requirements (see Section 2.1091), the following information is typically needed:
(1) Calculation that estimates the minimum separation distance (20 cm or more) between an antenna and persons required to satisfy power density limits defined for free space.
(2) Antenna installation and device operating instructions for installers (professional/unskilled users), and the parties responsible for ensuring compliance with the RF exposure requirement
(3) Any caution statements and/or warning labels that are necessary in order to comply with the exposure limits
(4) Any other RF exposure related issues that may affect MPE compliance ULTRATECH GROUP OF LABS 3000 Bristol Circle, Oakville, Ontario, Canada L6H 6G4 Tel. #: 905-829-1570, Fax. #: 905-829-8050, Email: vic@ultratech-labs.com, Website: http://www.ultratech-labs.com All test results contained in this engineering test report are traceable to National Institute of Standards and Technology (NIST) File #: MCRS-009F15C247 February 28, 2006 Page 158 FCC ID: NS906P21 FCC Part 15, Subpart C, Section 15.247 FHSS/DTS MHX921 - 900 MHz OEM Wireless Frequency Hopping / DTS Module, Model MHX921 Calculation Method of RF Safety Distance:
S = PG/4r2 =EIRP/4r2 P: power input to the antenna in mW EIRP: Equivalent (effective) isotropic radiated power S: power density mW/cm2 G: numeric gain of antenna relative to isotropic radiator r: distance to centre of radiation in cm Where:
r = EIRP/4S For portable transmitters (see Section 2.1093), or devices designed to operate next to a persons body, compliance is determined with respect to the SAR limit (define in the body tissues) for near-field exposure conditions. If the maximum average output power, operating condition configurations and exposure conditions are comparable to those of existing cellular and PCS phones, SAR evaluation may be required in order to determine if such a device complies with SAR limit.

METHOD OF MEASUREMENTS - AC MAINS CONDUCTED EMISSIONS AC Mains conducted emissions measurements were performed in accordance with the standard against Page 163 FCC ID: NS906P21 appropriate limits for each detector function. The test was performed in the shielded room, 24'(L) by 16'(W) by 8'(H). The test was performed were made over the frequency range from 150 kHz to 30 MHz to determine the line-
to-ground radio noise voltage which was conducted from the EUT power-input terminals that were directly connected to a public power network. The EUT normally received power from another device that connects to the public utility ac power lines, measurements would be made on that device with the EUT in operation to ensure that the device continues to comply with the appropriate limits while providing the EUT with power. If the EUT operates only from internal or dedicated batteries, with no provisions for connection to the public utility ac power lines, AC Mains conducted measurements are not required. Table-top devices were placed on a platform of nominal size 1 m by 1.5m raised 80 cm above the conducting ground plane. The EUT current-carrying power lead, except the ground (safety) lead, was individually connected through a LISN to the power source. All unused 50-Ohm connectors of the LISN was terminated in 50-ohm when not connected to the measuring instruments. The line cord of the EUT connected to one LISN which was connected to the measuring instrument. Those power cords for the units of devices not under measurement were connected to a separate multiple ac outlet. Drawings and photographs of typically conducted emission test setups were shown in the Test Report. Each current-carrying conductor of the EUT shall be individually tested. The EUT was normally operated with a ground (safety) connection, the EUT was connected to the ground at the LISN through a conductor provided in the lead from the ac power mains to the LISN. The excess length of the power cord was folded back and forth in an 8-shape on a wooden strip with a vertical prong located on the top of the LISN case. The EUT was set-up in its typical configuration and operated in its various modes as described in this test A preliminary scan was made by using spectrum analyzer system with the detector function set to PEAK mode (9 KHz RBW, VBW > RBW), frequency span 150 kHz to 30 MHz. The maximum conducted emission for a given mode of operation was found by using the following step-by-
report. step procedure:
Step 1. Monitor the frequency range of interest at a fixed EUT azimuth. Step 2. Manipulate the system cables and peripheral devices to produce highest amplitude signal relative to the limit. Note the amplitude and frequency of the suspect signal. Step 3. The effects of various modes of operation is examined. This is done by varying equipment operation modes as step 2 is being performed. Step 4. After completing step 1 through 3, record EUT and peripheral device configuration, mode of operation, cable configuration, signal levels and frequencies for final test. Each highest signal level at the maximized test configuration was zoomed in a small frequency span on the spectrum analyzer's display (the manipulation of cables and peripheral devices and EUT operation modes might have to be repeated to obtain the highest signal level with the spectrum analyzer set to PEAK detector mode 10 KHz RBW and VBW > RBW). The spectrum analyzer was then set to CISPR QUASI-PEAK detector mode (9 KHz RBW, 1 MHz VBW) and AVERAGE detector mode (9 kHz RBW, 1 Hz VBW). The final highest RF signal levels and frequencies were record.

Spurious Emissions (Radiated) The radiated emission measurements were performed at the UltraTechs 3 Meter Open Field Test Site Page 168 FCC ID: NS906P21
(OFTS) situated in the Town of Oakville, province of Ontario. The Attenuation Characteristics of OFTS have been filed to FCC, Industry Canada, ACA/Austel, NVLap and ITI. Radiated emissions measurements were made using the following test instruments:
1. Calibrated EMCO BiconiLog antenna in the frequency range from 30 MHz to 2000 MHz. 2. Calibrated Emco Horn antennas in the frequency range above 1000 MHz (1GHz - 40 GHz). 3. The test is required for any spurious emission or modulation product that falls in a Restricted Band, as defined in Section 15.205. It must be performed with the highest gain of each type of antenna proposed for use with the EUT. Use the following spectrum analyzer settings:
RBW = 100 kHz for f < 1GHz and RBW = 1 MHz for f > 1 GHz
VBW = RBW
Sweep = auto
Detector function = peak
Trace = max hold
Follows the guidelines in ANSI C63.4-1992 with respect to maximizing the emission by rotating the EUT, measuring the emission while the EUT is situated in three orthogonal planes (if appropriate), adjusting the measurement antenna height and polarization, etc.. A pre-amp and highpass filter are required for this test, in order to provide the measuring system with sufficient sensitivity.
Allow the trace to stabilize.
The peak reading of the emission, after being corrected by the antenna correction factor, cable loss, pre-amp gain, etc. is the peak field strength which comply with the limit specified in Section 15.35(b) Calculation of Field Strength:
The field strength is calculated by adding the calibrated antenna factor and cable factor, and subtracting the Amplifier gain (if any) from the measured reading. The basic equation with a sample calculation is as follows:

If a receiver reading of 60.0 dBV is obtained, the antenna factor of 7.0 dB/m and cable factor of 1.0 dB are added, and the amplifier gain of 30 dB is subtracted. The actual field strength will be:
Field Level = 60 + 7.0 + 1.0 - 30 = 38.0 dBV/m. Field Level = 10(38/20) = 79.43 V/m.

Now set the VBW to 10Hz, while maintaining all of the other instrument settings. This peak level, once corrected, must comply with the limit specified in Section 15.209. If the dwell time per channel of the hopping signal is less than 100ms, then the reading obtained may be further adjusted by a duty cycle correction factor, derived from 10log(dwell time/100mS) in an effort to demonstrate compliance with the 15.209.
Submit test data Maximizing The Radiated Emissions:
The frequencies of emissions was first detected. Then the amplitude of the emissions was measured at the specified measurement distance using required antenna height, polarization, and detector characteristics. During this process, cables and peripheral devices were manipulated within the range of likely configuration. For each mode of operation required to be tested, the frequency spectrum was monitored. Variations in antenna heights (from 1 meter to 4 meters above the ground plane), antenna polarization (horizontal plane and vertical plane), cable placement and peripheral placement were explored to produce the highest amplitude signal relative to the limit. The maximum radiated emission for a given mode of operation was found by using the following step-by-step procedure:
Step 1: Monitor the frequency range of interest at a fixed antenna height and EUT azimuth. Step 2: Manipulate the system cables to produce highest amplitude signal relative to the limit. Note the amplitude and frequency of the suspect signal. Step 3: Rotate the EUT 360 degrees to maximize the suspected highest amplitude signal. If the signal or another at a different frequency is observed to exceed the previously noted highest amplitude signal by 1 dB or more, go back to the azimuth and repeat Step 2. Otherwise, orient the EUT azimuth to repeat the highest amplitude observation and proceed. Step 4: Move the antenna over its full allowable range of travel (1 to 4 meters) to maximize the suspected highest amplitude signal. If the signal or another at a different frequency is observed to exceed the previously noted highest amplitude signal by 1 dB or more, return to Step 2 with the highest amplitude observation and proceed. Step 5: Change the polarization of the antenna and repeat Step 2 through 4. Compare the resulting suspected highest amplitude signal with that found for the other polarization. Select and note the higher of the two signals. This signal is termed the highest observed signal with respect to the limit for this EUT operational mode. Step 6: The effects of various modes of operation is examined. This is done by varying the equipment modes as steps 2 through 5 are being performed. Step 7: After completing steps 1 through 6, record the final highest emission level, frequency, antenna polarization and detector mode of the measuring instrument.
