1.RADIATED EMISSION OF TRANSMITTER (BASE) Standard: FCC Part 15 Test procedure: paragraph 15.205 paragraph 15.209 paragraph 15.247 Test equipment: TYPE BRAND EMITECH NUMBER Test receiver ESH3 Rohde & Schwarz 1058 Test receiver ESVS 10 Rohde & Schwarz 1219 Spectrum analyzer FSP 40 Rohde & Schwarz 4088 Loop antenna EMCO 1406 Biconical antenna HP 11966C Hewlett Packard 728 Log periodic antenna HL 223 Rohde & Schwarz 1999 Open site Emitech 1274 Antenna RGA-60 Electrometrics 1204 Low-noise amplifier 2 to 18 GHz Microwave DB 1922 High pass filter HP12/3200-5AA Filtek Antenna WR42 IMC 1939 Variac R213 Dereix 1419 Low-noise amplifier 18 to 26 GHz ALC 3036 Test set up: The system is tested in an open area test site (OATS). The test unit is placed on a rotating table, 0.8 m from a ground plane. Zero degree azimuth corresponds to the front of the equipment under test. Frequency range: from 9 kHz to harmonic 10 (Fcarrier ≤ 10 GHz) Bandwidth: 120 kHz (F < 1 GHz) or 100 kHz, following 15.205 or 15.247 1 MHz (F > 1 GHz) or 100 kHz, following 15.205 or 15.247 Distance of antenna: between 30 m and 3 m according the frequencies and the limits. Antenna height: 1 to 4 meters Antenna polarization: vertical and horizontal, only the highest level is recorded. Equipment under test operating condition: The equipment is blocked in continuous transmission mode, modulated by internal data signal.

Results: Ambient temperature (°C): 18 Relative humidity (%): 65 Power source: The polarity column refers to the antenna polarity at which the maximum emissions level is measured. FREQUENCIES Detector Antenna height Azimuth resolution Polarization Field strength Limits Margin (MHz) (cm) (degree) bandwidth H: Horizontal (dBµV/m) (dBµV/m) (dB) (kHz) V: Vertical 4882.3 Peak 245 150 1000 V 66.19 74* 7.81 4882.3 Avg 245 150 1000 V 47.78 54* 6.22 7323.4 Peak 234 327 1000 H 65.07 74* 8.93 7323.4 Avg 234 327 1000 H 47.25 54* 6.75 9763.9 Peak 263 0 100 V 51.97 87.67 35.7 * restricted bands of operation in 15.205, this limit corresponding at the 15.209 section. Applicable limits: In any 100 kHz bandwidth outside the frequency band in which the spread spectrum or digitally modulated intentional radiator is operating, the radio frequency power that is produced by the intentional radiator shall be at least 20 dB below that in the 100 kHz bandwidth within the band that contains the highest level of the desired power. The highest level recorded in a 100 kHz bandwidth is 107.67 dBµV/m on channel 40. So the applicable limit is 87.67 dBµV/m. In addition, radiated emissions which fall in the restricted band, as defined in section 15.205 (a), must also comply with the radiated emission limits specified in section 15.209 (a) (see section 15.205 (c)). TEST CONCLUSION: RESPECTED STANDARD
