Systems and methods for proactively enforcing a wireless free zone
First Claim
1. A method for proactively preventing wireless transmissions in a zone over a pre-defined area, the method comprising the steps of:
- a) performing radio frequency (RF) simulation of the pre-defined area, wherein the RF simulation is configured to provide placement location of sensors to provide a coverage area in the pre-defined area and to minimize signal bleed into areas neighboring the pre-defined area;
b) placing sensors in the pre-defined area responsive to the RF simulation; and
c) providing wireless data transmissions from the sensors to prevent wireless transmissions in the zone throughout the coverage area;
wherein the providing transmissions step comprises the steps of;
a) transmitting clear-to-send (CTS) frames with a long duration field to reserve a wireless channel thereby preventing other devices from communicating on the wireless channel; and
b) repeating step a).

Abstract
The present disclosure is directed to systems and methods for proactively enforcing a wireless free zone over an enterprise'"'"'s airspace using Open Systems Interconnect (OSI) layer one, two, and three based techniques. The systems and methods prevent wireless communications over IEEE 802.11 (WiFi), IEEE 802.16 (WiMax), and IEEE 802.15.1 (Bluetooth) networks to enable an enterprise to enforce compliance to a no-wireless policy. Smart antennas and coverage planning are included to avoid disrupting a neighbor'"'"'s wireless communications. Further, the disclosed systems and methods can be combined into existing Wireless Intrusion Prevention Systems (WIPS) or in a stand-alone sensor and server configuration to offer proactive no-wireless zones.

22. A system for proactively preventing wireless transmissions in a zone, the system comprising:
-
one or more sensors connected to a network, the sensors comprise one or more wireless radios configured to monitor a wireless network and to transmit frames on the wireless network; and a server connected to the one or more sensors through the network, the server configured to log events;
generate alarms, notifications, and reports; and
direct the one or more sensors to prevent wireless communications in the zone;wherein the one or more sensors are deployed in an area responsive to radio frequency (RF) simulations which predict the placement of the sensors to guarantee coverage over the area and to minimize signal bleed into neighboring areas, and wherein the one or more sensors are configured to transmit wireless frames in the zone thereby preventing wireless transmissions; wherein the one or more sensors transmit clear-to-send (CTS) frames with a long duration field to reserve the channel thereby preventing other devices from communicating over a wireless channel in the zone. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29)
