Aeroflex announces the addition of wideband AMR (adaptive multi-rate) support to its 6113 AIME (air interface monitor emulation) base station protocol test system, affecting the 3GPP TS45.003 test specification. The wideband AMR codecs (TCH/WFS12.65, TCH/WFS8.85, TCH/WFS6.60) build on existing narrowband AMR technology to improve the quality of voice services due to the wider speech bandwidth used. The base station protocol tester allows 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.
