What is Digital Advanced Wireless System (DAWS)?

Digital Advanced Wireless System, best known as DAWS, is a proposed standard for a multimegabit packet-switching radio network from the European Telecommunications Standards Institute (ETSI). The Digital Advanced Wireless System (DAWS) will be compatible with the existing packet radio system called the Terrestrial Trunked Radio (Tetra), which enables terminals to communicate directly with each other in regions without cellular coverage.

DAWS is being developed in response to the rapid deployment of Global System for Mobile Communications (GSM) wireless cellular communication systems and the increasing demand for high-speed wireless mobile data services in response to the phenomenal growth of the Internet in recent years.

The ultimate goal of the DAWS effort is to provide mobile wireless Asynchronous Transfer Mode (ATM) data communication services with full-terminal mobility over wide areas of roaming.

ATM has been selected by ETSI as the technology of choice for the backbone of the future envisaged European Information Infrastructure (EII).

DAWS will be designed to support applications that require data rates in excess of the 2-Mbps rate supported by the International Mobile Telecommunications-2000 (IMT-2000) standards, with eventual planned support for full ATM rates of 155 Mbps envisioned.

Examples include wireless networking, Internet browsing, video conferencing, file transfer, and Voice over IP (VoIP).
