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
L830-EB-11 module not support GNSS.
4.6 Antenna Design
The L830 module provides main and diversity antenna interfaces, and the antenna design requirements
as shown in the following table:
L830 module Main antenna requirements
Frequency range
The most proper antenna to adapt the frequencies should be used.
