Access control via selective direct and indirect wireless communications

A system is described for controlling a locking system restricting physical access (e.g. a door lock). The locking system is accessed (e.g., actuated and monitored) via dual communication path types used by a mobile wireless communication device. The locking system includes an electro-mechanical access control security device, and a receiving unit controlling the electro-mechanical access control security device. The receiving unit is paired with the mobile wireless communication device for receiving input from the mobile wireless device for activating the electro-mechanical access control security device using both low energy and high energy operating modes. The mobile wireless device is configured to access the locking system via both direct BLUETOOTH and indirect mobile wireless data network communications. Moreover, the operating range of the receiving unit is extended by connections to networked devices operating BLUETOOTH 4+LE at a high power-extended range mode through the use of an amplifier stage.
