Abstract
A remote access control system includes a remote wireless communicator to receive wireless information from a central access control system. It also includes a remote access controller electrically coupled to the remote wireless communicator. The remote access controller would receive information from the remote wireless communicator and uses the information to control locking and unlocking of the door. The remote wireless communicator also transmits wireless information to the central access control system and a switch is provided for selectively choosing between the receiving and transmitting the wireless information. The remote wireless communicator communicates via RF information and preferably spread-spectrum RF. The remote access control system also includes a reader to read user data when presented to the reader.
