Note:
The above values are measured for the dual antennas situation (Main+Diversity). For single
main antenna (without Diversity), the sensitivity will drop around 3dBm for each band of LTE.
4.5 GNSS
L850 module supports GNSS/BeiDou and AGNSS functions, and adopts RF Diversity and GNSS/Beidou
integrated antenna.
