Northwest EMC TCB Compliance Opinion Revision 05//02 RAFN0044 Information about the Applicant Applicant: Radioframe Networks, Inc. Address: 1120 112th Ave NE, Suite 600 City, State, Zip Bellevue, WA 98004 Test Requested By: Steve Peters Model: B-Series GSM 1.0 FCC ID: PURBSERIESGSMNA10 Agent Radioframe Networks, Inc. Approval Type Certification Equipment Type Base Station transceiver Rule Part 22H and 24E Overview GSM 850 This base station transceiver is designed for use in the GSM 800 MHz cellular telephone system. The transmitter will operate from 869.2 to 893.8 MHz. The receiver circuit supports 824.2 to 848.8 MHz. The base station operates in the 800 MHz broadband Cellular services as per 47 CFR Part 22 subpart H, 22.901 (d). It meets the requirements of GSM 1900 11.10-1 version 4.19.1 specification for operation in GSM cellular systems except for the output frequency range. This transceiver will in normal mode operate at a nominal output peak power of 16.44 mW per channel at the antenna connector. The power output is reducible to ~0.3 watts.. GSM 1900 This base station transceiver is designed for use in the GSM 1900 MHz cellular telephone system. The transmitter will operate from 1930.4 to 1989.6 MHz. The receiver circuit supports 1850.4 to 1809.6 MHz. The base station operates in the 1900 MHz broadband PCS services as per 47 CFR Part 24 subpart E. It meets the requirements of GSM 1900 11.10-1 version 4.19.1 specification for operation in GSM cellular systems. This base station will in normal mode operate at a nominal power out of 36.98 milliwatts at the antenna connector. The power output is reducible to ~0.3 watts. Northwest EMC TCB Compliance Opinion Revision 05//02 RAFN0044 Findings Finding 47 Cfr 2.1033(c)9) Tune-up procedure over the power range, or at specific operating power levels. Resolution Information has been provided. Finding 47 CFR 1.1310 Radiofrequency radiation exposure limits. The criteria listed in table 1 shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Sec. 1.1307(b), except in the case of portable devices, which shall be evaluated according to the provisions of Sec. 2.1093 of this chapter. Further information on evaluating compliance with these limits can be found in the FCC's OST/OET Bulletin Number 65, ``Evaluating Compliance with FCC- Specified Guidelines for Human Exposure to Radiofrequency Radiation.'' The RF Exposure Exhibit is not correct; PURIRAP10 has different output power characteristics listed in the different tables. Resolution New Exhibits have been provided Finding 47 CFR Sec. 15.19 Labeling requirements. (1) Receivers associated with the operation of a licensed radio service, e.g., FM broadcast under part 73 of this chapter, land mobile operation under part 90, etc., shall bear the following statement in a conspicuous location on the device: This device complies with part 15 of the FCC Rules. Operation is subject to the condition that this device does not cause harmful interference. Resolution Information has been provided.

Compliance with 47 CFR 15.247(b)(5) “Systems operating under the 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 Commission's guidelines. See § 1.1307(b)(1) of this Chapter.” The EUT will only be used with a separation distance of 20 centimeters or greater between the antenna and the body of the user or nearby persons and can therefore be considered a mobile transmitter per 47CFR 2.1091 (b). The GSM EUT can be configured for either the 850 or 1900 band. This document will provide calculations for the 850 band. The GSM EUT has two antenna ports. One antenna port is for transmit and the other is receive. The EUT will only be used in the applicant’s access point. The access point can accommodate seven radios. However the system only has enough power for a total of six transmitters. The access point can be configured for a maximum of two 802.11b radios (FCC ID: PURDH2) and a of four GSM transmitters (FCC ID: PURBSERIESGSMNA10) or a maximum of six GSM transmitters (FCC ID: PURBSERIESGSMNA10). The maximum peak power was measured to be 16.22mW (ERP) for FCC ID: PURBSERIESGSMNA10 and 76.7mW (ERP) for FCC ID: PURDH2. The EUT meets the requirement that it will be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines (ref. 47 CFR 1.1307, 1.1310, 2.1091 and 2.1093. Also OET Bulletin 65, Supplement C). The MPE Estimates are as follows: Table 1 in 47 CFR 1.1310 defines the maximum permissible exposure (MPE) for the general population as 1 mw/cm². The exposure level at a 20 cm distance from the EUT’s transmitting antenna is calculated using the general equation: S=(PG)/4πR² Where: S = Power Density (1 mw/cm²) P = power input to the antenna (mW) G = numeric power gain relative to an isotropic radiator R = distance to the center of the radiation of the antenna (20 cm = limit for MPE estimates) PG = EIRP Solving for S, the maximum power densities 20 cm from the transmitting antennas are summarized in the following tables: FCC ID: PURDH2 802.11b Radio Antenna Type Antenna Part # Transmit Frequency Max Peak Conducted Output Power Antenna Gain Minimum Antenna Cable Loss Power Density @20 cm General Population Exposure Limit from 1.1310 Ratio of Power Density to the Exposure Limit (MHz) (mW) (dBi) (dB) (mW/cm²) (mW/cm²) Omni ANT-2.4-RCT 240076.73.8500.037 10.037 FCC ID: PURBSERIESGSMNA10 GSM 850 Radio Antenna Type Distance to Antenna Transmit Frequency Max Peak Conducted Output Power Antenna Gain Minimum Antenna Cable Loss Power Density @ 20 cm General Population Exposure Limit from 1.1310 Ratio of Power Density to the Exposure Limit (cm) (MHz) (mW) (dBi) (dB) (mW/cm 2 ) (mW/cm 2 ) Omni 20 880.4 16.44 0 0 0.003 0.58693 0.006 Excerpts from TCB training “ Devices operating in multiple frequency bands ‰ When RF exposure evaluation is required for TCB approval o Separate antennas – estimated separation distances may be considered for the frequency bands that do not require evaluation or TCB approval, however, the estimated distance should take in to account the effect of co-located transmitters.
