Wireless data communications using DECT air interface

DECT is an approved ETSI standard for cordless communications, defined as a general radio access technology that can be used as the air interface to any network. In addition to the well-established voice service, it supports data communications. DECT currently addresses low bit rates, but additional modulation options have recently been included for high-speed, up to 2Mbps. In this paper, we describe the hardware and software design of an entire wireless communications system to be used in SOHO applications. While putting the emphasis on data communication, we demonstrate the feasibility of maintaining the compatibility with existent voice terminals. We developed generic hardware and software components, which revealed a very flexible approach. We easily created a wireless LANs, extended an Ethernet LAN and provided access to ISDN 1.
