The capabilities of cellphones, smartphones and handheld wireless devices have made mobile wireless a “source” of cyber threats and have drastically altered how government entities implement policies to protect sensitive information and corporations protect intellectual property

The use of entryway scanners had been considered an adequate solution for mobile device discovery with the assumption that the detection at entry points of a facility will eliminate the risk of these devices entering restricted areas. However,powering off devices, or temporarily removing the battery can make them undetectable by the scanners.

When examining available Wireless Intrusion Detection solutions (WIDS), security personnel must ensure that a selected
solution covers the full–spectrum of wireless frequencies used in commercial compact devices (cell, WiFi, and Bluetooth). That the solution can can provide information to the physical location of the wireless source to allow security personnel to quickly detect and identify its locale, and third,  be easy to operate, and provide the ability to be centrally managed so that large dispersed “no–wireless” areas such as campuses can be monitored under a single plane of glass.
