The present invention is secure wireless network. The secure wireless network can include multiple receiver nodes coupled to corresponding high-precision clocks. Each of the receiver nodes can be configured to receive wireless frames transmitted both within and outside a secured geographic area covered by the secure wireless network. A master synchronization high-precision clock can be coupled to the corresponding high-precision clocks. Additionally, a position location system can be coupled to the receiver nodes. Specifically, the position location system can be programmed to compute estimated positions for individual ones of wireless nodes transmitting the wireless frames. Finally, access management logic can be coupled to the position location system. More particularly, the access management logic can be configured to manage access to the wireless network by the individual ones of the wireless nodes based upon the computed estimated positions.

DETAILED DESCRIPTION The present invention is secure wireless network.
The secure wireless network can include multiple receiver nodes coupled to corresponding high-precision clocks.
Each of the receiver nodes can be configured to receive wireless frames transmitted from both within and outside a secured geographic area covered by the secure wireless network.
A master synchronization high-precision clock can be coupled to the corresponding high-precision clocks.
Notably, the high-precision clocks and the master synchronization high-precision clock can include nano-second resolution.
Importantly, a position location system can be coupled to the receiver nodes.
Specifically, the position location system can be programmed to compute estimated positions for individual ones of wireless nodes transmitting the wireless frames.
Finally, access management logic can be coupled to the position location system.
More particularly, the access management logic can be configured to manage access to the wireless network by the individual ones of the wireless nodes based upon the computed estimated positions.
In one aspect of the present invention, the position location system can include at least one two-dimensional position location system.
In particular, the two-dimensional position location system can include one of a hyperbolic position location system or an elliptical position location system.
In another aspect of the present invention, the position location system can include at least one three-dimensional position location system.
In that case, the three-dimensional position location system can include one of a hyperboloidic position location system and an ellipsoid position location system.
In a preferred aspect of the present invention, the access management logic can include a mapping of the secured geographic area.
To that end, one of an iconic and a textual indication of the computed estimated positions of the wireless nodes transmitting the wireless frames to the receiver nodes can be included about the mapping
