Abstract: A wireless theft detection system comprises a device holder and a docking station. The device holder includes a first wireless communication module adapted to establish a wireless link with an external second wireless communication module, a first alarm module, and a first processing module. The docking station includes the second wireless communication module, a second alarm module, and a second processing module. The first wireless communication module is adapted to generate first link quality information or the second wireless communication module is adapted to generate second link quality information, and both the first processing module and the second processing module are adapted to control the first and the second alarm module to generate a first and a second alarm signal, respectively, when a quality of the wireless link is below a predetermined threshold value.
