3-60 TM80 Telemetry Monitor Service Manual
Site test and report
1. Check that the surrounding environment and placement of devices
during the test are consistent with those actually in use.
2. Learn distribution of Wi-Fi devices and other 2.4G products in the wireless
scope.
3. According to the site environment, initially determine the rough
installation locations of APs, find the cleanest channel by using Wireless
network survey tool, for example, channel 11 is relatively cleaner, open
the test AP, and set the channel to channel 11. Use the Wireless network
survey tool to test wireless coverage and ensure that the test can be
passed in the expected coverage of the test AP.
Go to the next expected AP installation location, perform the test again, and record
the results.
Field personnel must ensure that no blind spot exists in the required coverage and
that co-channel interference does not exceed the limit.
