Tektronix: Network Location with Better Precision than Cell-ID
After failing to provide consumer geo-location services Wireless operators are back in the geo-location business with various use cases: geo-marketing, location-based marketing messages and more (anonymous or opt-in) that leverage network-based location technologies.

Unfortunately they are in most cases using cell-ID which accuracy is pretty poor: a few hundred meters in cities and a few kilometers in non urban environments.

This is where a technology from Tektronix Communications can be of help to wireless operators. The supplier to the wireless industry based in Plano, Texas, acquired 18 months ago Newfield Wireless, a company which focussed on Radio Access Network (RAN) geoanalytics, i.e. helping operators understand the strength of their network and the need for new base stations.

But this radio access network technology can also be used to determine the location of a subscriber with a better precision than Cell-ID.

When it comes to accuracy Tektronix Communications gave us a couple of metrics. In one test in London the average accuracy (measured against ground truth, i.e. smartphones with GPS) was 93 meters. In another test in France the technology gave results in a 200 meters radius around the real handset location while cell-ID had a radius of 1200 to 1400 meters.

“In that particular situation a big box retailer was trying to identify its visitorship against a competitor and cell-ID would not be accurate enough to produce interesting results, but our technology was,“ said Guillaume Le Mener, head of data monetization at Tektronix Communications, in an interview with GPS Business News at the recent Location-Based Services conference held in London.

In addition to the accuracy improvement over Cell-ID, Tektronix technology has a better refresh rate, providing about 30% more location events than Cell-ID.

Tektronix technology is software-based and is completely passive, purely listening to network equipments. It works over 2G, 3G and 4G and can scale up to more than 100 million subscribers while offering low latency.
