Previous Actions

The Telecommunications area of COST has already in its tradition a stream of very successful Actions that dealt with mobile and wireless communications, and have contributed to the development and standardisation of commercial systems:

COST 207, "Digital Land Mobile Radio Communications", March 1984 - September 1988, which contributed to the development of GSM, providing the channel model;

COST 231, "Evolution of Land Mobile Radio (Including Personal) Communications", April 1989 - April 1996, which contributed to the deployment of GSM1800 and to the development of DECT, HIPERLAN 1 and UMTS, and defined propagation models for the GSM band that are recommended by 3GPP and ITU-R;

COST 259, "Wireless Flexible Personalised Communications", December 1996 - April 2000, which contributed to the deployment of DECT and HIPERLAN 1 and to the development of UMTS and HIPERLAN2, conducted simulations over the dispute on the access technique for UMTS (TDMA versus CDMA), supporting ETSI on its decisions, and supported 3GPP in the development of a channel model;

COST 273, "Towards Mobile Broadband Multimedia Communications", May 2001 - June 2005, which contributed to standardisation efforts in 3GPP and to the deployment of UMTS networks, provided channel models for MIMO systems and initial inputs to the research on B3G generation systems.

The success of these activities can be measured in terms of the impact over the standardisation bodies mentioned above and the scientific quality of the research results reported, often recognised at worldwide level through the acceptance of many papers, previously presented at COST meetings, over the IEEE literature; additionally, the Final Reports of the previously mentioned Actions have been referenced in many papers published in international journals, by authors external to the Actions; also, these Actions have stably attracted researchers from North America and Asia-Pacific research institutions.

This Action gathers the group of researchers who participated in COST273, which prolonged the success of Actions COST207, 231 and 259.
