RF exposure evaluation According to§2.5.1, systems operating under the provisions of this section shall be operated in a manner that ensures that the device meets the SAR and/or RF field strength limits of RSS-102. Note: For the separation distance ≤ 5mm For f≥ 1.99GHz, The exemption limit is calculated as follow, exemption limit(mW)= -0.6873f 3 + 8.5147f 2 – 34.1288f + 46.613 f is GHz For 0.3≤ f ≤0.835GHz, The exemption limit is calculated as follow, exemption limit(mW)= -90.91f + 92.91 f is GHz So the limit for the common frequency is as follow, Frequency (MHz) 315 433.93 Limit (mW) 64.27 53.46 Result Channel Frequency (MHz) Electric field strength (dBuV/m)@3m ERP (mW) Limit (mW) Result 315 73.25 0.0000254 64.27 PASS 433.93 75.17 0.0000395 53.46 PASS Note: computational formula dBuV/m=20 log uV/m; EIRP= pt *gt =(E *d ) 2 *30; where E is the electric field strength in V/m; d is the measurement distance in meters (m) Result: Because the max tune up power is less than the exemption limit, so No SAR measurement is required.

Test Environment and Mode Operating Environment: Temperature: 25.0 C Humidity: 55 % RH Atmospheric Pressure: 1010 mbar Test Mode: Operation mode: Keep the EUT in continuous transmitting with modulation The sample was placed (0.8m below 1GHz, 1.5m above 1GHz) above the ground plane of 3m chamber. Measurements in both horizontal and vertical polarities were performed. During the test, each emission was maximized by: having the EUT continuously working, investigated all operating modes, rotated about all 3 axis (X, Y & Z) and considered typical configuration to obtain worst position, manipulating interconnecting cables, rotating the turntable,…
