Operators must be familiar with the requirements of the FCC Part 15 Regulations prior to operating any link using this equipment. For installations outside the United States, contact local authorities for applicable regulations. Interference Environment Manufacturers and operators of spread-spectrum devices are reminded that the operation of these devices is subject to the conditions that: •Any received interference, including interference from industrial, scientific, and medical (ISM) operations, must be accepted; and •These devices are not permitted to cause harmful interference to other radio services. If the operation of these systems does cause harmful interference, the operator of the spread- spectrum system must correct the interference problem, even if such correction requires the Part 15 transmitter to cease operation. The FCC does not exempt spread-spectrum devices from this latter requirement regardless of the application. The FCC strongly recommends that utilities, cellular stations, public safety services, government agencies, and others that provide critical communication services exercise due caution to determine if there are any nearby radio services that can be affected by their communications. Operational Requirements In accordance with the FCC Part 15 regulations: 1. The maximum peak power output of the intentional radiator shall not exceed one (1) watt for all spread-spectrum systems operating in the 2.4000-2.4835 GHz band. 2. Systems operating in the 2.4000-2.4835 GHz band that are used exclusively for fixed, point-to-point operations may employ transmitting antennas with directional gain greater than 6 dBi, provided the maximum peak output power of the intentional radiator is reduced by 1 dB for every 3 dB that the directional gain of the antenna exceeds 6 dBi. 3. Stations operating in the 2.4000-2.4835 GHz band that are used for fixed, point-to- multipoint operations may use transmitting antennas of directional gain greater that 6 dBi, provided the peak output power from the intentional radiator is reduced by the amount in dB that the directional gain of the antenna exceeds 6 dBi. 4. Fixed, point-to-point operation, as used in Point 2, excludes the use of point-to- multipoint systems, omni-directional applications, and multiple co-located intentional radiators transmitting the same information. The operator of the spread-spectrum intentional radiator or, if the equipment is professionally installed, the installer is responsible for ensuring that the system is used exclusively for fixed, point-to-point operations. 5. The operator of a spread-spectrum system is responsible for ensuring that the system is operated in the manner outlined inInterference Environmenton page xi. xiiAPCD–NC006–A Warnings and Advisories General Advisory Operator and maintenance personnel must be familiar with the related safety requirements before they attempt to install or operate the NCL1170 equipment. It is the responsibility of the operator to ensure that the public is not exposed to excessive Radio Frequency (RF) levels. The applicable regulations can be obtained from local authorities. WARNING! This system must be professionally installed. Antennas and associated transmission cable must be installed by qualified personnel. WaveRider assumes no liability for failure to adhere to this recommendation or to recognized general safety precautions. WARNING! To comply with FCC RF exposure limits, the antenna for this transmitter must be fix-mounted on outdoor permanent structures to provide a separation distance of 2 metres (6.6 feet) from all persons to satisfy RF exposure requirements. The distance is measured from the front of the antenna and the human body. It is recommended that the antenna be installed in a location with minimal pathway disruption by nearby personnel. WARNING! Do not operate the NCL1170 without connecting a 50-ohm termination to the antenna port. This termination can be a 50-ohm antenna or a 50-ohm resistive load capable of absorbing the full RF output power of the transceiver. Failure to terminate the antenna port properly may cause permanent damage to the NCL1170. WARNING! Connect only shielded cables (both the Serial and twisted pair Ethernet) to the NCL1170 RS-232 Serial (DB-9) and 10Base Tx Ethernet …

Response to TCB questions ----- Original Message ----- From: Certification Manager To: Acme Testing Sent: Thursday, February 15, 2001 2:01 PM Subject: FCC ID: OOX-WRM2000 We have completed our review and the following issues were identified: 1. Please confirm that the unit uses a single chip/symbol rate of 8:1 and that the chip/symbol rate of 11:1 available in the chip set is unused. At this time, the WRM 2000 supports only 5.5 Mbits/sec and 11 Mbits/sec CCK which uses a chip/symbol rate of 8:1. It does not support 1 Mbits/sec or 2 Mbits/sec modulation schemes which have a chip/symbol rate of 11:1. 2. Please provide bandedge plots documenting that the unit complies with the 15.205 limit at 2483.5MHz with the transmitter operating at channel 11. Use the highest gain antenna. Plots are provided for both band edges for channels 1 & 11 with the highest gain antenna 3. Please provide data responsive to the 15.31(e) requirement for input voltage variation. The transmitter was tested at 85% and 115% input voltage with no measurable change in power output. 4. The LISN was out of calibration on the date of testing. Please respond. Was it calibrated subsequently? Did the calibration return indicate that it was in calibration as received? The calibration information provided in the test report had a typographical error please see the attached revised page 12 of the test report for correct information. 5. Please explain why 24,000 MHz was selected as the upper end of the explored range when 15.33 requires exploration to the tenth harmonic or 24,620 MHz for this device. I apologize for this error and omission. The actual upper frequency range measured was 22 GHz. 22 GHz is the upper range of the HP 8566B spectrum analyzer. Previous discussions with the Engineers at the OET branch of the FCC indicated that it is an acceptable procedure to state “that by good engineering judgment and practice that if there are no detectable emissions over the range of 7.4 GHz to 22 GHz then there can be no emissions over 22 GHz”. TCB note: See FCC email exhibit 6. Please specify the label material. The material used for the Regulatory label is Mylar. Its adhesive is manufactured by 3M, part # 467MP. 7. The report specifies that testing was conducted with a shielded RS-232 cable. The users manual does not specify a shielded cable should be used when connecting to the RS-232 port. Please supply a corrected users manual. Modifications to the manual concerning the RS-232 cable. During normal operation the RS-232 cable is not attached to any of the units. It is only used for diagnostics or troubleshooting. Make modifications to the manual in the General Advisory section, under "Warnings and Advisories" , as give below: Change WARNING! Connect only shielded twisted pair (STP) Ethernet cable to the NCL1170 10Base Tx Ethernet (RJ-45) port. It is the responsibility of the installer to supply and use the correct type of Ethernet cable. To WARNING! Connect only shielded Serial and twisted pair Ethernet cables to the NCL1170 RS-232 Serial ( DB-9) and 10Base Tx Ethernet (RJ-45) ports. It is the responsibility of the installer to supply and use the correct type of Serial and Ethernet cables. 8. We have some concerns regarding the use of different antennas. We have noted the use of a unique connector but appendix D of the manual does not make it clear that the device can only be used with the tested antennas. Also for the dish antenna the gain is different from the report and on page 10 of the manual. From the test report the antenna gain results were calculated with 10m of cable and a filter. Appendix D discusses the use of different lengths. We need to be satisfied that only the tested antennas/cable/filter will be used with the device. 1)Antennas tested for use with the unit. For each type of antenna, the one with the maximum effective gain was used during test. For example the Omni antenna, with an effective gain of 9.0 dBi, was tested because it had the maximum gain that would be use with in the system. During install it could be possible to use an Omni with an effective gain of 5.0 dBi. 2) Dish Antenna Gain The report is correct, were it states the Dish Antenna gain is 24 dBi. The value stated on page 10 of the manual, referred to as the Maximum Antenna System Gain or maximum effective gain, is slightly different than antenna gain. It refers to the gain of the Antenna System which includes the antenna gain (24dBi) that is modified by losses due to cabling, filters and other passive components (3.5 dB). The maximum antenna system gain is then equal to 24-3.5=20.5 dBi. 3) Only tested antennas/cable/filter will be used with the device. a) This system is designed for commercial installations with outdoor antennas and is to be professionally installed. b) Only the antenna types tested will be used with this device. c) Only the filter tested will be used with this device. If other filters are to be second sourced they will have equivalent or superior performance and will be covered under a class I permissive change. d) Only LMR-400 or equivalent cable will be used. If other cable types are to be used they will be covered under a class I permissive change. The cable length could vary between different installations depending on the location of the antenna. But in any case, the antenna system gain will never exceed the value that unit was tested with. Thus, the radiated output RF power and spurs will be will either be equal to or less than those measured on the unit tested for FCC compliance. Best regards Barry C.

WRM-2000 Functional Overview The WRM-2000 radio module is based on the Intersil PRISM II Direct Sequence Chip Set. As shown in the block diagram located in Figure 1 and 2, there are ten basic units in this module: 1. Baseband Processor 2. Modulator/Demodulator 3. Dual Synthesizer 4. Up/Down Converter 5. Power Amplifier 6. Low Noise Amplifier (LNA) 7. RF VCO 8. IF VCO 9. Antenna (RF) Interface 10. MAC/Radio (buffered) Interface During transmission, the data to be transmitted is placed on the Baseband Processor TX data line. This data is modulated according to the format selected (CCK) and then spread using a defined PN code. Two signals are generated (the In-Phase (I) and Quadrature (Q) components). The I & Q signals are sent to the Modulator/Demodulator where they are first filtered and then modulated with the IF frequency (374 MHz). The IF oscillator generates a 748 MHz signal which is divided by two inside the Modulator/Demodulator, generating a final IF signal of 374 MHz. Next, the two signals are combined into a single signal and sent to the Up/Down converter. The Up/Down converter will shift this signal to the RF frequency for the channel programmed in the synthesizer, for operation within the 2.4GHz ISM band. In the final stage, this signal is amplified to produce +25 dBm RF power output as measured at the output of the antenna port. In the receive mode, the radio signal is amplified by the LNA, and then sent to the Up/Down converter. The Up/Down converter down-converts this signal from the 2.4GHz range to the IF frequency, 374MHz. The Modulator/Demodulator then converts the signal to baseband and splits the signal into its I & Q components, before sending it to the Baseband Processor. Finally, the Baseband Processor despreads and demodulates the data contained in the CCK format, and places it on the RX data line. Bi-directional, translating buffers are used to interface between controller (5V) and radio module (3.5V) logic levels. The RF and IF Local Oscillator signals are generated using the synthesizer and voltage controlled oscillators. The dual synthesizer is programmed with the desired RF channel frequency less the IF frequency. The baseband processor and the synthesizer are driven from a common 44MHz oscillator to control the timing of these chips. Example (for Channel 1 operation): RF IF LO 2412 MHz – 374 MHz = 2038 MHz The antenna (RF) connector is connected to a 50-ohm impedance matched transmission line (Times Microwave LMR-400 or LMR-600) to one of the following antenna types: Omni, Patch, Yagi and Dish. The table below includes examples of each of the recommended antenna types, as well as their associated maximum antenna system gain.
