![]() ![]() ![]() There is no black/white answer to what constitutes a successful connection.Measured or reported values vary by modem, carrier, and network environment.Both Signal Strength and Signal Quality must be considered for successful cellular data connection.In this case, even though you have a great Signal Strength value, you may not achieve maximum mobile data speeds. 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. ![]()
