EUT Exercising Software:Provided by manufacturer Descriptionof EUT The Equipment Under Test (EUT) is aIntelligent Wireless RouterSystemoperated at 2.4GHz. DSSS for IEEE 802.11b ; OFDM for IEEE 802.11g/n Operation Principle: This Systems using embedded MIMO RF transceiver consists of two receivers and two transmitters used to form a complete 2.4GHz ISM band Wireless LAN application. The EUT shall be simultaneous transmission at the antenna 0 and antenna 1 for 802.11g , 802.11n HT20 or HT40, 802.11b mode shall be transmission only single antenna (antenna 0 or antenna 1). Since the EUT can communicate with computer via LAN port, this report is to demonstrate the EMC test result for this function. As per client declaration, the model JHR-N815R, JHR-N835R, JHR-N845R, JHR- N855R, JHR-N865R, JHR-N875R, JHR-N885R, JHR-N895R, which utilize the identical circuit design, PCB layout, shielding and interface with the model JHR- N825R, only the cosmetic is difference. Therefore the mainly perform test on JHR- N825R model. 1.4Equipment Modification No modification was done by TÜV SÜD China 1.5Related Submittal(s) Grants This is a signal application subject to Certificate Authorization.

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 turntable, varying antenna height from 1m to 4m in both horizontal and vertical polarizations. The emissions worst-case are shown in Test Results of the following pages. 3.2Field Strength Calculation The field strength at 3…
