During the test, the EUT was connected to laptop PC and then a test program was executed to operate EUT continuously. The operating voltage of EUT was 5 Vdc supplied from a USB port on Laptop PC. The EUT was tested at the lowest channel, middle channel and the highest channel with the maximum output power in accordance with the manufacturer’s specifications. The worst data were recorded in the report. The EUT is programmed with the following setting during the testing: Test frequency 2412 MHz 2437 MHz 2462 MHz 802.11b Programed Level 11 16 16 Data rate (Mbps) 1 1 1 802.11g Programed Level 1E 1D 1D Data rate (Mbps) 54 54 54 802.11n Programed Level 1E 1E 1E Data rate (Mbps) MCS7 MCS7 MCS7 Test Report No.: NK-12-R-015 FCC and IC Certification Samsung Electronics Co., Ltd.
