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.It seems like with band steering turned on it is connecting to 5ghz no matter what (at least for my android phone). Even turning wifi off/on on the phone didn't help and it still connected to the 5ghz side of things. The UDM controller shows a signal level of -90db. I take a look at my phone and it is weakly connected to the 5ghz network. However, we all know that logicial thinking and theory don't work for wifi networks too well! I was outside at a point I thought would be out of range or at least very minimal coverage. The theory was that a client would attempt to connect to the 5ghz SSID first (due to band steering) and if the signal level was less than -72db it would then try the 2ghz band and if the signal was still not strong enough it would roam to a different AP or disconnect completely. Set the power level of 2ghz to medium and 5ghz to high Set the minRSSI on both 2ghz and 5ghz to -72db My thought was to create my configuration as such:
