SIP-based femtocell convergence solution provider Tatara Systems and Airvana (AIRV) have partnered on a live SIP-based femtocell demonstration at Tatara’s booth at CTIA Wireless 2009. The demonstration will utilize the Tatara Convergence Server (TCS), the industry’s first SIP-based application server to focus on an all-IP approach to femtocell integration and the Airvana HubBub CDMA femtocell.
Femtocells have the potential to extend the reach of a mobile operator’s network into homes and enterprises, enhancing coverage and providing capacity for bandwidth-hungry applications. Tatara was the first vendor to deliver a SIP-based solution for femtocell network integration, and Airvana pioneered the use of SIP/IMS technology in CDMA2000 femtocells. As noted by industry analysts, IP-based femtocell deployment is the only method that offloads the legacy mobile core infrastructure, thereby providing the capacity needed for 3G service delivery and enabling operators to recognize substantial cost savings through OPEX and CAPEX optimization.
The Tatara Convergence Server solution enables the interconnection of femtocells and other advanced technology IP-based radio network elements with the legacy macro network, providing the full mobile voice, messaging and data experience in an IP environment supporting both VoIP and IMS networks. The TCS capabilities include authentication of the mobile subscribers, handoff between femtocells and the macro network, emergency and supplementary services, as well as delivering new IP-based applications to existing mobile handsets without modifying or disrupting the macro network. The TCS is available in a CDMA or GSM/UMTS variant.
Airvana’s HubBub CDMA supports both 1xRTT voice and EV-DO mobile broadband data.
