Wifi Revolution

Receiving its seventh U.S. patent, AirTight Networks, a provider of wireless intrusion prevention systems (WIPS) and wireless vulnerability management, has announced that the company has been awarded another U.S. patent, number 7,406,320, by the United States Patent and Trademark Office (USPTO). For applications such as wireless intrusion prevention systems and asset tracking for WiFi (News - Alert) networks, this patent provides powerful location tracking technology.

 

A good location tracking technology relies upon certain density of received signal strength indicator (RSSI) measurement points. AirTight's sensors are used with the signal strength measurements of Cisco (News - Alert) APs for location tracking purposes, as AirTight provides for integration of its WIPS with Cisco's WLC (Wireless LAN Controller). The combined RSSI measurements are processed in AirTight's location tracking engine. This allows the infrastructure AP hardware to be used to complement WIPS sensors to achieve the required density of RSSI measurement points. Customers can also obtain the benefits of AirTight's robust location tracking engine.

 

AirTight now has a total of seven U.S. patents along with an Australian patent. It has more than 25 U.S. and international patents pending. The company states that many of these patents are expected to be granted this year.

 

A wireless environment is full of intrinsic uncertainties arising out of factors such as variability of device RF characteristics, dynamic nature of a wireless environment while performing location computations and incomplete specification of RF space. AirTight's location tracking technology uses a predictive approach and takes into account all these uncertainties. Even if the above mentioned uncertainties are present, the technology offers powerful location tracking with high accuracy. Without the need for extensive calibration or site-surveys, the technology can achieve desired location tracking performance with minimal deployment overhead.

 

“While the theory of location tracking using triangulation has been around for a few years, making it work in real-life, indoor environments for critical applications such as security and asset tracking has remained a challenge," said Dr. Hemant Chaskar, director of technology at AirTight. "AirTight has overcome this challenge through research and innovations to deliver powerful and cost effective location tracking technology for WiFi applications.”
