Abstract
A system and method for providing security to a wireless network by using a mobile node's location as a parameter for deciding if access is to be given to the node. The system and method employ access points, wireless routers and mobile nodes, each including at least one transceiver adapted to transmit and receive communication signals to and from other wireless routers, mobile nodes and other mobile access points. Each access point is connected to a network management system which allows enhanced network monitoring and control. Each network node includes technology which may determine an absolute node location containing latitude, longitude and altitude of a node, or a relative node location containing the distance and angle between nodes, or a combination of both absolute and relative location data.
