Innovative and integrated hybrid positioning solution delivers fast and pervasive mobile location performance. Mobile World Congress 2011 Booth: C30, Hall 2.1

Mobile World Congress, Barcelona, Spain – Rx Networks Inc., a leading mobile location technology company, today announced the commercial availability of its new XYBRID RT™ version 1.0 real-time hybrid positioning service. XYBRID RT, to be demonstrated during Mobile World Congress, uniquely combines Wi-Fi®, Cellular and Assisted-GPS technologies to achieve optimal device location determination in environments where satellite-based navigation alone may not always work. The service is designed for use in mobile devices, Global Navigation Satellite System (GNSS) chipsets, or location applications. It also provides a direct positioning solution for mobile operators, whether for their home network or as a solution to LBS roaming.

XYBRID RT, accessed through a simple HTTP interface, can work with any application or device form factor. It can be integrated with several leading GNSS chipsets to supply assistance data that improves Time-To-First-Fix. When a location is required, the device submits a list of currently detected Wi-Fi access points and cell towers to the XYBRID RT server. The server responds with an estimated position based on these observations as well as with satellite orbit assistance data (ephemeris) to help the GNSS chipsets quickly acquire a precise location. This hybrid assistance accelerates signal acquisition and improves GNSS receiver sensitivity in challenging areas, including indoor and dense urban locations. A device’s location can be closely determined within 3 to 5 seconds while the solution rapidly converges to GPS-level accuracy, improving the end-user mobile location experience.

The service uses an extensive global database of cell tower and Wi-Fi access point locations. The database is dynamically populated and updated by client devices using the service, and is also supplemented with existing third-party databases where necessary. This cost-effective approach ensures that the database is self-learning and self-adapting to wireless network changes. While benefiting from the aggregate database growth from multiple partners, individual partners also have the option of retaining data collected through their own client devices.

XYBRID RT operates in an anonymous manner without exposing the identity of individual devices. This ensures privacy for both individuals and security-sensitive Mobile Resources Management (MRM) and Machine-to-Machine (M2M) applications. The XYBRID RT service includes real-time satellite ephemeris from Rx Networks’ proven GPStream GRN™ Global Reference Network, a worldwide grid of GNSS reference stations with highly redundant, real-time views of multiple satellite constellations. The XYBRID RT service is built from the same carrier-grade (99.999% availability) network that Rx Networks’ customers rely upon for E-911 and other priority services.
