Aeroflex has announced the addition of Wideband AMR (Wideband Adaptive Multi-Rate) support to its highly successful 6113 AIME basestation protocol test system. The new test capability relates to the 3GPP TS45.003 test specification. The new Wideband AMR codecs (TCH/WFS12.65, TCH/WFS8.85, TCH/WFS6.60) build on existing narrow band AMR technology and their introduction will significantly improve the quality of voice services due to the wider speech bandwidth used.

 “Wideband AMR features need to be correctly configured, optimised and maintained if subscribers are to get the full quality of service benefits that the new speech codecs can deliver,” said Ross Broadhurst, Product Marketing Manager, Aeroflex Test Solutions Wireless Division. “The launch of the new Wideband AMR test capability on our 6113 AIME protocol test system is of significant benefit to infrastructure developers who will be able to develop, integrate and test Wideband AMR basestation capabilities, in advance of the mobile handset capability becoming available.”

A powerful test and development tool, the Aeroflex 6113 AIME basestation protocol tester allows infrastructure developers to create and test new GSM basestation software and hardware features by providing a mobile emulation. Combining the 6113E test set with the 6113E AIME (Air Interface Monitor Emulation) software package, it provides software engineers with a layer 1, layer 2 and layer 3 monitoring and emulation capability for the Um interface. Software engineers can monitor, debug and fault find the layer 1 and protocol interchanges on the Um interface with fully decoded display of layer 2 and layer 3 messages. In addition, the 6113 AIME protocol test system features sophisticated script editing, debugging, execution and automation facilities, logging of all air interface signalling and logging of all traffic frames.
