Intrusion Detection through Leaky Wave Cable in Conjunction with Channel State Information

This paper presents design and implementation of a low-cost system solution. A light-weight wireless device is used for surveillance of suspicious activities at highly sensitive areas. The devices such as transceivers operating at 2.4 GHz are deployed in indoor settings. Finer-grained Channel State Information in conjunction with pair of leaky wave cable detects any intruder in the area. The intrusion detection is identified at a particular subcarrier frequency. The processing of the measured data over time is analyzed and used for reporting the disturbances. Deploying leaky wave cable as transmitter and receiver has benefits in terms of wider coverage area, covering blind and semi blind zones. The system fully exploits the amplitude and phase information of Channel State Information provided by Intel 5300 NIC and its associated driver. The experimental results demonstrate greater level of accuracy in a cluttered environment.
