This chapter is an overview of recommended signal strength levels for different mobile service modes.
This chapter is an overview of recommended signal strength levels for different mobile service modes.
<b>Note: </b> The following recommendations apply for both Quectel and MeigLink modules used in Teltonika devices.
==Signal Measurement==
==Signal Measurement==
Signal strength values are defined by a few different measurements which vary even more for different service modes. These measurements are as follows:
Signal strength values are defined by a few different measurements which vary even more for different service modes. These measurements are as follows:
*[[RSSI]]
*[[RSSI]]
*[[RSRP and RSRQ|RSRP]]
