Agilent intros radio network analysis tool for 3G

Agilent Technologies Inc. announced what it touts as the first integrated test solution that—in a single protocol analysis tool—seamlessly combines mobile device data captured from an RF interface and from a mobile terrestrial network.

Troubleshooting and optimising today's 3G networks requires a broad understanding of network performance over multiple interfaces. Rapid growth in the number of subscribers and in data-network usage has challenged the 3G radio access network in both RF capacity and data throughput performance; measuring across the last hop from base station to mobile device is essential for troubleshooting and optimisation; and without visibility to the air interface, network operators must manually correlate data from independent drive test and protocol analysis tools.

Importing Agilent's E6474A Drive Test data through the Agilent J7839A signalling analyser has revolutionised and simplified end-to-end troubleshooting. It is now possible to leverage the high-performance signalling analyser platform by analysing information from the radio interface with network protocol traces. The analyser is available for both UMTS and cdma2000 technologies, providing data import, automatic correlation call trace and sequence diagram representations. The new Agilent solution allows users to correlate signalling procedures from the air interface and radio access network interfaces in a single view to detect and troubleshoot problems from the mobile phone to the network, leading to true end-to-end visibility.

"Traditional RF and network-based tools have their parts to play in this complex environment, but getting the best out of discrete tools can be a labour-intensive and complex process," said Chris Witt, general manager of Agilent's next generation wireless division.

The J7839A signalling analyser import of E6474A drive test data is available now.
