Abstract: A wireless device access system employs short-range wireless communication to detect the proximity of a user device to a structure and a wide-area data network to communicate an unlock request. The access system then authenticates the unlock request and the proximity of the user device prior to transmitting an unlock command to the structure. Additionally, the wireless device may require the proximity of a user token prior to operation and/or the access system may include an override within the structure blocking any unlock command. Besides providing access to the structure, the system may perform other functions, such as monitoring room occupancy, switching power on and off, and the like.
