1) Case 1: Single ABG in One Room: The results of communication error metric show that the client application received all the broadcasted messages correctly. The reason there was no error in the communication is that small rooms donothave reverberation. Withno reverbtheclient application can correctly identify short pulses of particular frequencies. In this case the average time of discovery metric show that the overall average time of discovery noted was 3.26 seconds ranging from a minimum of 2.141 to a maximum of 4.406 seconds.ThisvariationisduetocommunicationfromtheABG to the client device is a one way broadcast as the message is an inaudible audio signal played by the ABG repeatedly. If the user requests a service scan during a broadcast, that information is neglected and the client application waits for and decodes the next broadcast.
2) Case 2: Single ABG in a Large Room: The client device received almost all the broadcasted messages correctly on all the spots. Considering a small room an ideal environment for the system, the average time of discovery recorded was 3.3 seconds ranging from a minimum of 2.136 seconds to a maximum of 5.002 seconds.
