SiRFLoc Server is a carrier-class, standards compliant, multimode aided-GPS location server that enables wireless operators to support a wide range of location-based services (LBS) with minimal impact on their network infrastructure. Incorporating SiRF’s patented multimode technology, SiRFLoc Server allows LBS applications to “shift gears” between several network-aided and autonomous positioning modes to control network loading and achieve greater operational efficiency.

Designed expressly for wireless location-based services deployment, SiRFLoc Server is both highly flexible and scalable. Offered through SiRF’s infrastructure partners in a carrier-class network location server, SiRFLoc Server can be implemented by wireless operators or Wireless Application Service Providers (ASP). It supports key standard wireless air interfaces and location service protocols, including RRLP for GSM/GPRS, RRC for WCDMA, PDDM for CDMA2000, IS-801 for CDMA and DLP for NTT DoCoMo, and non-standard protocols for Wireless ASPs. SiRFLoc Server is designed to support both aided (MS-Assisted and MS-Based) GPS and autonomous positioning methods, as well as hybrid Cell ID - GPS and other advanced hybrid positioning methods. Depending on network loading, QoS and application requirements, SiRFLoc Server can dynamically mix the various positioning methods and location service protocols within location sessions. Operators can install SiRFLoc Server in the user plane for faster, less costly deployment, as well as in the control plane, and can efficiently expand their networks as user traffic increases by running multiple servers.
