Effective radiated power test 6.1 Operating environment Temperature: 0~40 ℃ Relative Humidity: 50 % Atmospheric Pressure 1023 hPa 6.2 Test setup & procedure The average output power was measured on the EUT using a 50 ohm SMA cable connected to power meter via peak power sensor. Power was read directly and cable loss correction (2.0 dB) was added to the reading to obtain power at the EUT antenna terminals. The test was performed in temperature controlled chamber at normal conditions, extreme conditions and 3 channels (lowest, middle and highest channel). The average effective radiated power shall be equal to or less than –10 dBW (100 mW) EIRP. 6.3 Measured data of EIRP test results

7. Frequency range test 7.1 Operating environment Temperature: 0 ~ 40 ℃ Relative Humidity: 53 % Atmospheric Pressure 1023 hPa 7.2 Test setup & procedure The frequency range of the equipment is determined by the lowest and highest frequencies occupied by the power envelope. For all equipment the frequency range shall lie within the band 2.4 GHz to 2.4835 GHz (i.e. fL > 2.4 GHz and fH < 2.4835 GHz). During the test, the RBW was set at 100 kHz. fH is the highest frequency of the power envelope. fL is the lowest frequency of the power envelope.

8. Spurious emission test 8.1 Operating environment Temperature: 24 ℃ Relative Humidity: 50 % Atmospheric Pressure 1023 hPa 8.2 Test setup & procedure Where these measurements are made with a spectrum analyzer, the following settings were used: Resolution B.W : 100 kHz; Video B.W : 30 kHz; Detector mode : positive peak; Sweep time : Auto The measurements were performed from 30 MHz to 12.75 GHz. The EUT and its peripherals are placed on a turntable that is 1.5 meter above ground. The turntable can be rotated 360 degrees to determine the position of the maximum spurious emission level. The test frequency from 30MHz to 1 GHz, the EUT is measured at the distance of 3 meters and the test frequency above 1 GHz, the EUT is measured at the distance of 1 meter. The antenna can be moved up and down between 1 meter and 4 meters to find out the maximum emission level. Both horizontal and vertical polarizations of the antenna are set on measurement.


8.3 Transmitter Spurious Spurious emissions shall be measured as below: a) Transmitter Spurious is defined the noise that is out of the operation frequency band. b) Spurious emission can be measured either by Conducted method, or measured by

Radiated method. c) The EIRP shall be measured by Radiated method with cabinet antenna.

Spurious emission for transmitter limits

Frequency Range Limit when operating Limit when in standby 30 MHz to 1 GHz -36 dBm -57 dBm

Above 1 GHz to 12.75 GHz -30 dBm -47 dBm 1.8 GHz to 1.9 GHz 5.15 GHz to 5.3 GHz -47 dBm -47 dBm

Spurious emission for receiver limits

Frequency Range Limit 30 MHz to 1 GHz -57 dBm

Above 1 GHz to 12.75 GHz -47 dBm

Uncertainty was calculated in accordance with NAMAS NIS 81. Expanded uncertainty (k=2) of radiated emission measurement is ±2.45 dB. Expanded uncertainty (k=2) of conducted emission measurement is ±2.26 dB.
