Unlike localized solutions, such as Wi-Fi and Bluetooth, PoLTE’s technology leverages its Positioning over LTE (PoLTE) Macro software to achieve precision of 2 to 6 meters. The technology makes use of the sounding reference signals (SRS) embedded in an LTE handset user’s transmission. Using adapted radar location techniques, it converts portions of the LTE uplink signal into a probe signal.

The technology enables mobile network operators to deliver highly accurate location data to customers in indoor and outdoor environments.

Traditional macro cell location methods require at least three towers to see the user device to locate the device with precision. Historically, single tower deployments were limited in accuracy to the width of the sector created by the 120-degree antenna that was serving the user device. For example, at a distance of 1.5 kilometers from a base station, the cross range precision would be 4,000 meters. PoLTE Macro can improve the precision to less than 2 meters.

The benefits to leveraging network-based positioning include speed, flexibility, accuracy and data analytics. Customers for the technology include machine-to-machine and Internet of Things technologies, mobile advertising, crowd and customer tracking, and public safety.
