3-66 TM80 Telemetry Monitor Service Manual
Then calibrate the RSSI of Wireless network survey tool to TM80 when do site survey
(the RSSI of TM80 is the benchmark to wireless coverage).
3.8.3 Confirm Network Feasibility
Wireless coverage and AP capability and compatibility are decided by infrastructure
of network, it can’t be modified easily. If the network does not meet the
requirements before TM80 is installed, network dropping-off may happen easily
after installation.
Verify these requirements to confirm network feasibility. For verification contents
and method, see3.11.2Environmental Survey Table.
Site survey: To confirm coverage, perform coverage test in the asserted
areas including toilet ,corridor, stairs and other place whereTM80 may be
used. The service person can finish the wireless network survey via
third-party professional survey tool such as tamograph, Wirelessmon or
other professionalnetwork survey tool. The RSSI of TM80 is the
benchmarkto wireless coverage. So it’s necessary to calibrates the RSSI of
the wireless network survey tool with TM80. The site survey must be
carried out when the network is operational and other devices are
wirelessly connected.During the test, the WLAN SSID broadcasting
function must be enabled for TM80.
RF environment simulation: Some customers may carry out theoretic
design for deployment of APs by using a simulation tool or deploying
analysis tool. The work can accelerate network deployment but air
interface detection cannot be omitted. This is because the location, power,
and channel of an AP may be adjusted during actual deployment.
