3.8.2 Wi-Fi Signal Calibration
Before a Wireless network survey tool (running on laptop computer) is used to test
network coverage, calibrates the RSSI of wireless network survey tool with TM80.
Keep the TM80 and Wireless network survey tool close. The distance between them
is not greater than 30cm and the distance from human body is above 50 cm. Move
the TM80 and Wireless network survey tool at the same time (maintain the previous
distance). When the TM80 reads the following RSSI values: -50dBm,-60dBm, -70dBm
and -80dBm, record the RSSI values read by Wireless network survey tool.
