To satisfy FCC RF exposure requirements for both base and mobile 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:
Changes or modifications not expressly approved by Microhard Systems Inc. could void the users authority to operate the equipment. This device has been tested with MMCX and Reverse Polarity SMA connectors with the antennas listed in Appendix A When integrated in OEM products, fixed antennas require installation preventing end-users from replacing them with non-approved antennas. Antennas not listed in the tables must be tested to comply with FCC Section 15.203 (unique antenna connectors) and Section 15.247 (emissions). WARNING:
To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this may depend on the details of how the module is integrated with the host, the grantee (the party responsible for the module grant) shall provide guidance to the host manufacturer for compliance with the Part 15B requirements. WARNING:
MAXIMUM EIRP FCC Regulations allow up to 36 dBm 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. WARNING:

General 2.0 Product Overview The N2420B is a high-performance embedded wireless data transceiver. Operating in the 2400 - 2483.5 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 N2420B 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 N2420B 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 N2420B to interface directly to any equipment with an asynchronous serial interface.
ease of installation and use the N2420B 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. N2420B 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 N2420B 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 N2420B transmits. The N2420Bs 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 N2420B 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 N2420B module. 3.1 Estimating the Gain Margin Successful communication between N2420B 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 N2420B 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 N2420B 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 Transmitter 30 dBm Output Power Receiver Sensitivity =
-105 dBm MHX-920 Operating Manual: 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 N2420B 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 N2420B 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 B 0 2 4 2 N 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. N2420B Operating Manual:Glossary 5 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 N2420B is generating RF energy. Always ensure that the N2420B 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 N2420B is generating RF energy. Always ensure that the N2420B 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 N2420B 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 N2420B 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. 6 N2420B Operating Manual: Glossary 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 N2420B 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 N2420B radio modem. If you require another type of antenna please contact Microhard Systems Inc. The N2420B 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. N2420B Operating Manual:Glossary 7 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 N2420B 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?

General 2.0 Product Overview The N2420B is a high-performance embedded wireless data transceiver. Operating in the 2400 - 2483.5 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 N2420B 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 N2420B 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 N2420B to interface directly to any equipment with an asynchronous serial interface. ease of installation and use the N2420B 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. N2420B 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 N2420B 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 N2420B transmits. The N2420Bs 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 Approx. Output Power

Installation 3.0 Overview Qualified and experienced personnel must carry out the installation, removal or maintenance of all antenna components. The N2420B 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 N2420B module. 3.1 Estimating the Gain Margin Successful communication between N2420B 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 N2420B 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 N2420B 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 Transmitter 30 dBm Output Power Receiver Sensitivity =
-105 dBm MHX-920 Operating Manual: 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 N2420B 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 N2420B 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 B 0 2 4 2 N 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. N2420B Operating Manual:Glossary 5 3.2.2 Installing External Cables, Antennas and Lightning WARNING:
To satisfy FCC/IC RF exposure requirements for mobile transmitting devices, a separation distance of 25 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 N2420B is generating RF energy. Always ensure that the N2420B equipment is powered down during installation. WARNING:
Never work on an antenna system when there is lightning in the area. 6 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 N2420B is generating RF energy. Always ensure that the N2420B equipment is powered down during installation. At all times a distance of 25 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 N2420B 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 N2420B 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. N2420B Operating Manual: Glossary 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. WARNING:
Antenna 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 N2420B 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. 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 N2420B radio modem. If you require another type of antenna please contact Microhard Systems Inc. The N2420B 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. N2420B Operating Manual:Glossary 7 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 N2420B 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 N2420B 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 N2420B 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 N2420B Operating Manual: Glossary A.

(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. 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 into which the module is installed. Such coupling may result in noncompliant operation. 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 mobile and fixed applications. A minimum of 23cm separation distance is required from any user to meet FCC RF Exposure requirement Instructions are provided in the user manual for the integrators to comply with FCC Part15, Subpart B, and any other applicable FCC requirements. The receiver is verified. End-users must comply with the following instruction sated in the users manual:
- Labeling requirement for equipment using this modular transmitter.
- RF Exposure compliance with FCC Rules 2.1091 and 1.1307 when the radio is used in a mobile or base system
- Other Instructions provided by the manufacturer for third party integrators as stated in the User manual. Manufacturers Clarification The modular transmitter has its own RF shielding Tel: (403) 248-0028 Fax: (403) 248-2762 E-mail: info@microhardcorp.com www.microhardcorp.com Leaders in Wireless Telecom 2. 3. 4. 5. 6. 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. 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 but can apply to limited modular approvals under paragraph (b) of this section. 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)). 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 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 a unique coupling antenna connector MMCX. The modular transmitter was tested in a stand-alone configuration The module transmitter is equipped with a permanently affixed label displaying its FCC identification number. A sample exterior label is shown on Page iii of the user manual submitted with filing.

In the latter case, a copy of these instructions must be included in the application for equipment authorization. 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. The modular transmitter must comply with any applicable RF exposure requirements in its final configuration. 7. 8. Please refer to the user manual for instructions provided by the manufacturer for third party integrators. A minimum separation distance of 23 cm is required for both mobile and fixed installation of this module in order to satisfy the FCC RF Exposure requirement as stated on Page iii of the user manual.

N2420B Regulatory Requirements WARNING:
To satisfy FCC RF exposure requirements for both base and mobile 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:
Changes or modifications not expressly approved by Microhard Systems Inc. could void the users authority to operate the equipment. This device has been tested with MMCX and Reverse Polarity SMA connectors with the antennas listed in Appendix A When integrated in OEM products, fixed antennas require installation preventing end-users from replacing them with non-approved antennas. Antennas not listed in the tables must be tested to comply with FCC Section 15.203 (unique antenna connectors) and Section 15.247 (emissions). WARNING:
To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, if a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certified module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this may depend on the details of how the module is integrated with the host, the grantee (the party responsible for the module grant) shall provide guidance to the host manufacturer for compliance with the Part 15B requirements. WARNING:
MAXIMUM EIRP FCC Regulations allow up to 36 dBm 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. WARNING:
EQUIPMENT LABELING The FCC and IC numbers depend on the model of the radio module. Do NOT use the Marketing Name of the product but the Model to distinguish the Certifications Numbers. This device has been modularly approved. The manufacturer, product name, and FCC and Industry Canada identifiers of this product must appear on the outside label of the end-user equipment. SAMPLE LABEL REQUIREMENT for Model: N2420B:

5.9.1. Limit 15.247(b)(5): Systems operating under provisions of this section shall be operated in a manner that ensures 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). 5.9.2. 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 FCC Part 15, Subpart C, Section 15.247 - FHSS 2400MHz OEM Wireless Module, Model n2420B Page 65 FCC ID: NS911P31
(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 Calculation Method of RF Safety Distance:
S = PG/4r2 =EIRP/4r2 Where:
r = EIRP/4S 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 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. When SAR evaluation data is not available, and the additional supporting information cannot assure compliance, the Commission may request that an SAR evaluation be performed, as provided for in Section 1.1307(d) FCC Part 15, Subpart C, Section 15.247 - FHSS 2400MHz OEM Wireless Module, Model n2420B 5.9.3. Test Data Page 66 FCC ID: NS911P31 Evaluation of RF Exposure Compliance Requirements RF Exposure Requirements Compliance with FCC Rules Minimum calculated separation distance between antenna and persons required: *18 cm Manufacturer instruction for separation distance between antenna and persons required: 23 cm. Antenna installation and device operating instructions for installers (professional/unskilled users), and the parties responsible for ensuring compliance with the RF exposure requirement Antenna installation and device operating instructions shall be provided to installers to maintain and ensure compliance with RF exposure requirements. Caution statements and/or warning labels that are necessary in order to comply with the exposure limits Any other RF exposure related issues that may affect MPE compliance Refer to Users Manual for RF Exposure Information. None.
*The minimum separation distance between the antenna and bodies of users are calculated using the following formula:
RF EXPOSURE DISTANCE LIMITS: r = (PG/4S)1/2 = (EIRP/4S)1/2 S = 1 mW/cm2 EIRP = 36.0 dBm = 1036/10 mW max. (Worst Case) r = (EIRP/4S)1/2 = (1036/10/4(1)) 1/2 = 18 cm
