System and Method for Wireless Communications Activity Within a Predetermined Area and for Generating Messages to Selected Communication Devices

摘要

A system and method is disclosed for detecting the presence and level of wireless communications activity within a predetermined area, without disclosing the identity of the wireless users, and for generating a message to certain information and communications devices in response to the detection of a predetermined level of wireless communications activity within the predetermined area. The information detected also may include information relating to the general direction and rate of movement of detected wireless devices. The message generated in response to the detection of wireless communications activity may include wireless messages, including Short Message Service (SMS) messages, to persons desiring or needing to receive such information; messages to public officials and other interested persons; and automatic signals to devices such as computers, computer networks (including the internet and wireless networks), facsimile machines, signs, lights, loudspeakers, and other devices providing information through other communication and information media.

主权项

1. A system comprising:
a radio-frequency receiver apparatus configured to receive, from a wireless communication device, a wireless transmission having a wireless communications frequency; a signal processor configured to generate an analog electrical signal corresponding to the wireless transmission received and, using an analog-to-digital converter, convert the analog electrical signal to a post-conversion digital electrical signal without demodulating the wireless transmission, wherein the post-conversion digital electrical signal comprises information indicating a time of receipt of the wireless transmission; a computing processor; and a computer-readable storage medium comprising computer-executable instructions that, when executed by the computing processor, cause the computing processor to perform operations comprising:
receiving the post-conversion digital electrical signal, andstoring the information of the post-conversion digital electrical signal.
