A SYSTEM AND METHOD FOR DETERMINING PHYSICAL LOCATION OF A NODE IN A WIRELESS NETWORK DURING AN AUTHENTICATION CHECK OF THE NODE

摘要

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.
