Meru Networks has introduced RF Barrier(tm), the first IEEE 802.11-based technology for proactively defending wireless networks against eavesdroppers and “parking lot” attackers.
RF Barrier uses wireless LAN technology to block the radio-frequency (RF) signals from the corporate network as they exit the building, without disrupting internal WLAN operation. This limits an attacker’s ability to eavesdrop on data and perform offline analysis.
