The first part of the response is RSSI (Received signal strength indicator) and the possible values are, To find out what signal qualities are supported, The response for the AT+CSQ comamnd is also interpreted for teh corresponding dBm value. doi: 10.26599/ Online AT Command Tester tool, you can get the signal level of the device.

Wattananavin T., Sengchuai K., Jindapetch N., Booranawong A. An important advantage of the presented solution is the adjustment of the localization system accuracy at the assumed level of energy radiated by radio emitters based on the RSSI signal received power estimation.Īutomatic transmitter power control (ATPC) indoor localization received signal strength indicator (RSSI) short range devices (SRD) wireless radio sensors. This paper presents an adaptive power control algorithm for a transmitter, as a reference emitter, operating in power-saving mode.
In the issue of determining the location of radio emitters, various radio signal propagation models are used to determine the effective range and distance of the sensor-receiver from the radio emitter. There are many localization methods that have proven useful in practice and that use a reference radio signal for this purpose. In localization systems based on the emission of reference radio signals, an important issue related to the reliability of sensor operation is the problem of operating time and power of the emitted reference radio signal.
