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 with D/G antenna, including GPS/GLONASS/BDS. GNSS feature and
performance are as below table.
