ABSTRACT:
A method of providing security for network access radio systems and associated access radio security systems used with the systems. The method includes connecting an access radio having a radio link to a network; communicating between the access radio and a computer over the network using a ping application having ping commands and unique encrypted codes; and enabling operation of the access radio when the access radio is receiving ping commands. Typically, the access radio and the computer are nodes on the network and the network is a local area network (LAN). The ping application sends packets of information from the computer to the access radio and receives a response from the access radio. The ping application must be functioning (i.e., sending and receiving commands between the computer and the access radio) to enable the access radio to communicate via the radio link with a remote network.
