The RSSI Location Principle: Why is More Infrastructure Needed for Accuracy?
Image Credit: Extronics Ltd Received signal strength indication (RSSI) location principle utilizes received signal strength to establish the location of the transmitting device. A wireless device emits a signal and that signal is received by an access point or gateway. Multiple access points will collect the signal and results in the received signal strength being established by each access point. The greater the distance between the access point and the transmitting device, the weaker the sig...
