WASHINGTON – A new smartphone technology may be able to pinpoint a location to the centimeter.

says it’s developed the chip that, according to a , uses everything from GPS signals, Wi-Fi hot spots and cell towers to determine exactly where a person is (as long as they have their phone on them).

Technology Review reports the chip utilizes sensors that can receive a wide array of signals from GPS, Wi-Fi hot spots and cell towers. It’s possible the chip could determine what floor a person is on inside of a building.

Broadcom calls this “ubiquitous navigation.” The feature is touted as a new type of e-commerce. In theory, retailers could know exactly when customers walk through the front door of a store and, if they’re looking for a specific item, immediately send them a coupon.
