PEER AND COMPOSITE LOCALIZATION FOR MOBILE APPLICATIONS
First Claim
1. A mobile device, comprising:
- a radio component that establishes peer-to-peer communication with at least one additional mobile device; and
a localization component that estimates the physical distance between the mobile devices based on one or more characteristics of the peer-to-peer communication;
wherein at least one of;
the radio component uses a plurality of radio technologies simultaneously to establish and maintain the peer-to-peer communication, or the localization component enables multi-hop peer-localization, and maps the location of the mobile devices onto a grid.

Abstract
A system and method for peer based localization system using radio technology, such as Bluetooth or Wi-Fi ad-hoc technology that enables mobile devices such as cell phones, smart phones, laptops, handheld communication devices, handheld computing devices, satellite radios, global positioning systems, PDAs, etc. to discover their physical location relative to one another. In addition, the peer based localization can use a plurality of radio technologies to increase the accuracy of the physical location estimates. Additionally or alternatively, the peer based localization technique can be combined with infrastructure based location techniques, such as triangulation, GPS, or infrastructure based Wi-Fi localization in order to transpose virtual coordinates into physical coordinates.
