RADCOM Updates 3G Testing to Support All Protocols

RADCOM has announced the availability of an addition to its UMTS test solution suite. The new UTRAN testing application, which runs on the award-winning PrismLite analyzer, provides decoding of signaling and user data stacks on the Iub and Iur interfaces, including FP, MAC, RLC, RRC, GMM/SM, PDCP, PPP and IP layers, using manual or automatic channel setup detection. This new capability combines with existing AAL5 support of ALCAP, NBAP and RNSAP protocols to give customers protocol coverage of all UMTS traffic layers.

"High-bandwidth mobile service delivery mechanisms, such as data plane transport, terminal feature support, WCDMA coding schemes, and soft/softer handovers, traverse the network in a complex amalgam of encapsulated data over ATM AAL5/AAL2" said Doron Milchtaich, Cellular Technologies Product Manager. "Furthermore, NBAP (Iub), RANAP (Iu) and RNSAP (Iur) interfaces each have complicated transport channel structures that prevent straightforward analysis. The difficulty of ensuring QoS in this complex environment required our customers to look beyond traditional protocol analysis. With several major UMTS vendors as beta partners, RADCOM succeeded in giving the PrismLite the ability to troubleshoot these interfaces with ease. Coupled with its abilities to monitor different technologies at the same time and reassemble AAL5 data in real time, the PrismLite provides superior UMTS protocol support."
