What People are Saying About Polaris

“Just as buildings make a unique visual impression, they also impart a unique radio shadow loss at each mobile location to signals from surrounding base stations. The Wireless Location Signatures method makes use of the unique shadowing properties of buildings to determine where a mobile is. Other methods, such as GPS and TDOA, were created for line-of-sight propagation conditions and are degraded or defeated by shadowing. The Polaris Wireless Location Signatures (PWLS™) technology makes use of what is a unique feature of cities, rather than trying to force a line-of-sight solution into the shadows.”

“Polaris Wireless's approach to wireless E911 and location-based technology is refreshingly straightforward. The Polaris system provides accuracy, regulatory compliance, proven performance and rapid deployment-all at reduced expense to wireless carriers. The company's laser-like focus on providing a simple and reliable E911 solution will surely benefit network operators, subscribers, public safety agencies and the public at large. In addition, the Polaris solution provides a simple solution to those carriers already deploying another E911 technology who want to take advantage of location-based service revenue without delaying or derailing their E911 implementation strategy.”

“Providing an accurate, reliable method for identifying the location of mobile phones is a crucial problem in the wireless industry. Polaris Wireless has addressed the issue in a unique and exciting way. The company’s technology provides a solution that works very well both for the cell phones owned by existing customers and as a complement to future GPS-based solutions.”

“When widely deployed, wireless terminal location techniques based on signal signatures will provide location information over a wider service area and more accurately than other location techniques based on Time Difference of Arrival (TDOA), Angle of Arrival (AOA) or Augmented GPS (A-GPS). Both TDOA and AOA require reliable signals for at least three base stations to provide location information, but these are not available for many user locations. Also, heavy multipath severely degrades the accuracy of both time difference and angle measurements. A-GPS degrades or does not work at all when too many satellites are blocked from view in city streets and within buildings where the augmentation cannot overcome the losses for enough satellite paths. Signal signature location techniques do not suffer from these problems. Often the ‘richness’ of signatures in heavy multipath improves the accuracy of this technique. Signature techniques can provide some location information from fewer than three base stations (although with degraded accuracy).”

“Polaris Wireless is providing an accurate, economical solution to meeting the FCCs Phase II E911 mandate. With this technology, wireless carriers can locate callers 100 percent of the time, an impressive yield figure. In addition, the system can be deployed across entire networks in a fraction of the time required by other technologies. The industry and the public at large have needed such a ubiquitous, fast solution to wireless E911 location problems.”
