Pre-Competitive R&D Activities
The Digital Enhanced Cordless Telecommunication standards have evolved over the
past decade - the term DECT was first coined by ETSI in January 1988 at the beginning of
the formal specification process. First standards emerged in 1992. An
extensive range of enhancement and extensions, including notably the DECT Profiles - such
as the ISDN profile and the GSM interworking profile - have emerged in subsequent years.
In support of this extensive standards development activity, the relevant
technology has been the subject of widespread and in-depth research and development in
industrial and academic laboratories around the world. This page provides links to
some of these institutions and summaries, where available, of the type of work undertaken.

ACTS/RACE Projects involving DECT
The ACTS and RACE programmes are pre-competitive research
programmes supported by Directorate General XIII of the European Commission.
Projects undertaken under these programmes are essentially collaborative between academia
and industry, with some 50% of the costs covered by the industrial participants and the
remainder by the EC. The following projects under these programmes have included an
element of DECT R&D.
EXODUS (Experiments On the Deployment of UMTS)
The EXODUS Project is a key activity taking DECT forward within the framework of the ACTS
programme. A number of papers have been published based on work from EXODUS, including this one from Italtel and this one
from the official ACTS site, and one presented
as a UMTS Access Technology" by Arik Elberse, Teltec, (Ireland)
Published at the ACTS Telecommunication Summit, Granada, Spain, Nov. 27-29th 1996.
This paper proposes DECT as a fully featured and capable UMTS Access Technology. It
explains how the features and extensive standardisation of DECT can be leveraged to allow
DECT to provide UMTS services through its seamless integration and interworking with
future wired and wireless networks. This approach would avoid the unnecessary and
undesirable evolutionary path which involves multi-technology Core Networks and multiple
incompatible handsets and terminals. It would thus allow the existing and future
investments in GSM (through its already standardised interworking to DECT) and DECT-only
mobile networks to be maintained. The paper builds on work undertaken as part of the ACTS
Evolution to support Mobility in DECT Access Network" by Roberta Gobbi, presented
at the recent ISS '97 Congress (Toronto, Sept. 21-26). This paper outlines the EXODUS
project's activities in achieving a suitable transition from CTM towards UMTS with a set
of UMTS services to be implemented in the second phase field trials.
A variety of internet-based
services using mobile terminals was demonstrated by the EXODUS project, using DECT as
the radio access technology, at the IS&N Conference in May 1997 in Turin, Italy - 4th
International Conference on Intelligence in Services and Networks,
COBUCO (COrdless BUsiness COmmunication system)
The COBUCO project aims to
design, develop and experiment with an UMTS demonstrator system using state-of-the-art
DECT and ATM technology and offering cordless and fixed multimedia and multirate services
to the private business environment.

This project has been working towards the development of the product concept embodied in
its title, with work from the project feeding into the MPEG4 standardisation activity.
A DECT-based demonstrator has been built to implement the compression technology
and demonstrate feasibility.

investigations into time dispersion and propagation pathloss in order to make a general
coverage prediction model for DECT deployment. Another area of research is antenna
configurations and diversity techniques for base stations.

University of Limerick
DECT protocol stack development with Linux interface
The objective of this project is to develop a DECT protocol stack that interfaces with the
Linux operating system and then to investigate the performance of this DECT stack.
The project will be based around the National Semiconductor PC Development Kit and the TS
1220 DECT Protocol Analyser. The National Semiconductor Kit includes and ISA
Development Board which supports the Physical and MAC Layers of DECT. Initially, a
simplified model of the DECT Layer will be implemented (C/C++) and this will have the
capability to communicate with the DECT MAC and Physical Layers on the National
Semiconductor Board. Later, a more complex DLC Layer will be developed to take Error
Correction into account. Further development may follow . The Development will be
primarily concerned with the C-Plane of the DLC Layer.
