Aeroflex 6113 AIME

Aeroflex has added Wideband Adaptive Multi-Rate (AMR) support to its 6113 Air Interface Monitor Emulation (AIME) base station protocol test system.

The Wideband AMR codecs (TCH/WFS12.65, TCH/WFS8.85, TCH/WFS6.60) build on existing narrowband AMR technology and their introduction will significantly improve the quality of voice services due to the wider speech bandwidth used.

The Aeroflex 6113 AIME base station protocol tester enables infrastructure developers to create and test new GSM base station software and hardware features by providing a mobile emulation. Combining the 6113E test set with the 6113E AIME 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. The 6113 AIME protocol test system also features sophisticated script editing, debugging, execution and automation facilities, and logging of all air interface signaling and traffic frames.

"Wideband AMR features need to be correctly configured, optimized and maintained to give subscribers the full quality of service that the new speech codecs can deliver," said Ross Broadhurst, product marketing manager, Aeroflex test solutions, wireless division. "This new feature to our 6113 AIME protocol test system allows infrastructure developers to develop, integrate and test Wideband AMR base station capabilities. And they can to do so in advance of the mobile handset capability becoming available."
