Aeroflex has launched an AMR (Adaptive Multi-Rate) option for its 6113 EDGE basestation tester to complement its existing GSM and GPRS/EDGE test capability. AMR is a relatively new network upgrade that improves customer satisfaction and retention by enabling operators to substantially improve the quality of their voice services. AMR features need to be properly set up, optimized and maintained if subscribers are to get the full quality of service benefits that AMR can deliver. The AMR option extends test coverage to enable testing of AMR-specific elements of the basestation; in particular, those parts that include AMR codecs in the signal path.
