==GNSS Jamming==

Also, GNSS Jamming functionality is capable to separate indoor areas (e.g. underground parking) from events when jamming is actually happening. This is possible because in-band jamming will affect internal PGA (Programmable Gain Amplifier) degrade, as a result, CNR (Carrier-to-noise ratio) will degrade as well. On the other hand, if CNR degrade is degraded only because of underground or signal covered, internal PGA gain will keep almost the same.

Note: GNSS Jamming is not available on 3.80, 3.82 GNSS modules. Available on 5.10, 5.1.5, 5.1.8 or newer modules. GNSS module version can be checked by SMS\GPRS command - getver
