Patent ID: 8346285

Claim:
A system, for providing an output message responsive to detection of a plurality of wireless transmissions between a plurality of wireless communications devices located within a predetermined area and a wireless communications network, comprising: a processor; and a computer-readable medium having instructions that, when executed by the processor, cause the processor to perform operations comprising: comparing a characteristic associated with the plurality of wireless transmissions detected to a threshold in a comparison act, comprising performing at least one operation selected from a group of operations consisting of: determining whether the characteristic associated with the plurality of wireless transmissions bears a first relation to the threshold; and determining whether the characteristic associated with the plurality of wireless transmissions bears a second relation to the threshold; generating, in response to results of the comparison act, an output control signal, the generating comprising generating a first control signal if it is determined that the characteristic associated with the plurality of wireless transmissions bears the first relation to the threshold, and generating a second control signal if it is determined that the characteristic associated with the plurality of wireless transmissions bears the second relation to the threshold; and transmitting, in response to the output control signal, the output message to a recipient communication device, being distinct from the plurality of wireless communications devices, to convey information regarding the predetermined area, the transmitting comprising transmitting a first message if the first control signal is generated and transmitting a second message if the second control signal is generated.
