Embodiment Construction

[0012] figure 1 A high level block diagram of a system 100 for neutralizing improved explosive devices is depicted in accordance with a preferred embodiment of the present invention. Mobile network system 102 and broadband RF transmitter 104 are installed in vehicle 114 for transportation through areas where IEDs may be present. The wideband RF transmitter 304 is used to increase the level of the noise floor 106 within a predetermined area around the mobile network system 102 . The noise floor 106 is effective over a wide frequency spectrum (eg, from 450Mhz to 2100Mhz) where there is a "notch" around a particular frequency (eg, 900Mhz). Portable GSM, GPRS or WCDMA systems operate at power levels above the noise floor 106 on this 900 Mhz frequency. The notch (not shown) causes mobile or wireless terminals operating on the 900 Mhz frequency, eg within range of the mobile network platform 102 (typically within the noise floor), to camp on the mobile network system 102 . Once t...

Abstract

A method and system of disabling a remote improvised explosive device (IED) that is triggered by a cell phone. A portable wideband network system, installed in a vehicle, is used to determine operator frequency or frequencies active on a route along which the vehicle will travel. The vehicle includes a wideband transmitter for raising a radio frequency noise floor across all of the active cellular frequencies in a limited area surrounding the portable wideband network system during passage along the route. A notch filter is used by the system for filtering a particular frequency from the noise floor. The power level of the portable wideband network system is increased so that the strongest signal at the particular frequency in the limited area is provided by the portable system's base station. All mobile terminals in the limited area around the vehicle are connected to the portable system and the portable system prevents call completion of any of the connected mobile terminals.

Description

technical field [0001] This application relates to the use of mobile telecommunications networks for the protection of mobile military convoys from improvised explosive devices. technical background [0002] IEDs, or improvised explosive devices, are a common tool used by terrorists. An IED typically includes an explosive charge, a detonator (ie, a detonator) and an initiator for initiating the detonation of the detonator. One of the most common devices used as starters is a mobile terminal (hereinafter also referred to as a cellular phone, or mobile phone). The IED may be triggered (activated) from a remote location by placing a call, sending a message, or otherwise activating the ringer / speaker electronics of the IED-connected mobile terminal. The cell phone is the starter, and the substitute call causes the phone's ringer to ring, usually sending power for the ringer to a detonator that detonates the explosive. [0003] Due to the use of cellular phones for criminal ac...
