SteelCloud, Inc. was recently awarded U.S. Patent No. 7,020,476 (“Wireless network security”) by the USPTO, claiming a secure wireless network and method. This patent, issued late last month, states that it “can be applied to the problem of wireless LAN security when considering unauthorized attempts to access a wireless LAN by an unknown intruder from a position falling geographically outside a permissible geographic boundary” where the then-current disclosed technology was insufficient. The main network claim discloses a system comprising “plurality of receiver nodes coupled to corresponding high-precision clocks and configured to receive unsolicited wireless frames transmitted both from within and outside a secured geographic area covered by the secure wireless network,” a precise clock linked to additional precise clocks, a position location system that is linked to the received nodes that computes positioning information, and “access management logic” coupled to the system with specific configurations to manage wireless network access. Brian Hajost, the President of SteelCloud, has stated that this patent “addresses that problem effectively and was created through practical experience and extensive research.”
