Agilent Technologies Inc. has licensed acticom's Robust Header Compression (RoHC) protocol stack, further expanding Agilent's VoIP test capabilities in 1xEV-DO.

The stack is now part of Agilent's enhanced multiflow packet application functionality and is available in the 1xEV-DO lab application running on the 8690 wireless communications test set. With this capability, the test set, says Agilent, can emulate a network that supports efficient VoIP transmission using the RoHC stack.

RoHC is a standardized (RFC 3095) method of compressing the IP, UDP, RTP and TCP protocol headers of Internet packets. It compresses header information in data packets from 40 bytes to 1-3 bytes, greatly increasing the efficiency of VoIP packet transportation through packet data networks. RoHC is now a mandatory feature in 3G networks, and may one day be included in WiMAX.

"As a leader in the measurement industry, Agilent is fully committed to supporting the needs of engineers working on advanced wireless communication networks like 1xEV-DO," said Niels Fach?, VP and general manager of Agilent's mobile broadband division. "Providing early test solutions for enhancements such as RoHC provides engineers with the tools they need to ensure quality in the early phases of designreducing time-consuming re-work and overall design time."

The Agilent 1xEV-DO lab applications work with Agilent's 8960 wireless communications test set. The lab application supports test of multiflow packet application and enhanced multiflow packet application with multiple, simultaneous IP flows (16 forward and 16 reverse), each with their own quality of service parameters. These flows can be low-latency flows, which are required for near real-time applications such as video telephony and gaming. The 8960 test set can be used for wireless device development, manufacturing and repair of all major 2G, 2.5G, 3G and 3.5G wireless technologies. It provides test solutions for mobile devices across the entire lifecycle on a single platform.

The Agilent E6706B/U 1xEV-DO lab application with the acticom RoHC protocol stack is currently available via subscription to the E6720A 1xEV-DO lab application annual contract, priced at $10,400 for a one-year subscription.
