Turn off your cell phones, please

ECE researchers, with colleagues at George Washington University, are developing a system to detect and identify cell phones, pagers and other emitters in a building or area.

The Range Limited Antenna (RLA) system can detect emitters within a specified area, obtain detailed information, such as frequency, range, and angle, and locate and track the emitter. “Identifying and tracking emitters is important in high security buildings and in hospitals and other places that use highly sensitive equipment,” said Amir Zaghloul, the Virginia Tech lead on the project. The system uses two patch antenna arrays mounted on an elevated platform, with an adjustable angle for detection at varied floor heights.
