NOTE 
  The personnel who implement the Wi-Fi network survey should be well 
trained about Wi-Fi. If professional network engineers are not 
available, please ask some third party for help. 
 
 
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.
