For example, you may have an excellent RSSI value of -51 dBm, but the Tower Load (the number of mobile users) in your area is very high. Therefore, measurements like Signal Strength (RSSI) and Signal Quality (EC/IO) do not incorporate all of the relevant factors to describe the quality of the connection.
Physical barriers (mountains, buildings, trains, etc.).Signal going through a cellular repeater.There are many different factors that influence signal strength and quality, including but not limited to: More on these measurements in separate service mode sections. Signal strength values are defined by a few different measurements which vary even more for different service modes. Note: The following recommendations apply for both Quectel and MeigLink modules used in Teltonika devices. This chapter is an overview of recommended signal strength levels for different mobile service modes. 6 How do I check the signal quality on a RUT device?.4 3G (WCDMA, TDSCDMA, CDMA, EVDO, CDMA-EVDO).2.1 Determining Factors of Signal Values.
