AirMagnet today said it has received a notice of allowance for a U.S. Patent covering multiple methods of identifying “spoofed” or counterfeit devices in a wireless LAN.

The methods were co-developed by AirMagnet’s CTO, Chia-Chee Kuan, as well as Chief Architect, Miles Wu, and President and CEO, Dean Au.

The technology in the patent application detects counterfeit APs by finding anomalies in wireless traffic, such as devices whose actual beacon frame rate differs from the announced or expected frame rate. Additionally, counterfeit APs can be identified by detecting an abundance of out of sequence packets, which could indicate that potentially two devices are transmitting with the same identity.
