Audio Aspects

  • Dag Åkerberg

Cordless telephones use radio to provide the telephone user with the benefit of mobility. Conventionally, users of mobile radio have tolerated the poor speech quality often associated with an analogue radio channel. However, to today’s consumer the cordless telephone is viewed simply as another telephone and the same high speech quality associated with the fixed telephone network is expected. This chapter on audio aspects considers the requirements for, and outlines the approaches adopted in, the provision of good speech quality. It addresses in particular the special requirements arising in a Private Automatic Branch Exchange (PABX) environment and/or over local, national and international Public Switched Telephone Networks (PSTNs) when one or both telephones use digital cordless rather than wired links.
