Wireless cell

Optimum antenna alignment
To allow you to find the optimum alignment of the antenna connected to the SMA socket,
you can use the "Wireless cell" tab. The "Wireless cell" tab allows you to test the signal
strength at various antenna positions.
The information is updated at intervals of a few seconds. To be able to find the optimum
position, you receive immediate information about the signal strength at the test positions.
Status of the wireless cells
Display of parameters of the mobile wireless cell where the CMR is currently booked in:
● Wireless cell identifier (CI)
● Signal strength (CSQ / dBm)
Signal strength of the mobile wireless network as CSQ (Cell Signal Quality) and as
received signal strength RSSI [dBm]
CSQ and RSSI correspond as follows:
– CSQ = 0 .. 8 (-112 .. ≤ -97 dBm): No reception possible
– CSQ = 9 .. 16 (-95 .. -81 dBm): Medium signal quality
– CSQ = 17 .. 31 (≥ -79 dBm): Good signal quality
– CSQ = 99 (≤ -113 dBm): No signal detectable
● Signal quality
Signal quality as a percentage
● Location Area Code
Location identifier
● Mobile wireless standard of the wireless cell
● Network type
● Network name
● PLMN
Public Land Mobile Network
Worldwide unique identifier of mobile wireless networks consisting of:
– MCC (Mobile Country Code)
– MNC (Mobile Network Code) of the network provider
Example: PLMN 26276 is made up of MCC = 262 and MNC = 76.
