Note the parameter “CSQ”; this is an important indication of the signal strength with the
antenna in the current position.
The best location for the antenna must now
be found by comparing the CSQ value at
various alternative locations.
Select the “Hardware tests” tab.
Then click on the “Modem” button.
The modem is the cellular
communications module built into
Sentinel 2.
A new window will open with various
types of modem tests.
Click on the “CSQ” button.
This measures the received signal
strength, and a new measurement is
made every few seconds.
CSQ values are in the range of 1 to 33. A
higher number is better. We recommend
a CSQ value of greater than 7 within the
chamber, with lids closed, to facilitate
reliable communication.
Move the antenna to various alternative locations to find the most suitable position.
Stand well back from the antenna whilst the measurement is being made to ensure you
are not blocking the signal.
To stop the test, click the CSQ button once more.
