The TETRA enhanced data service (TEDS) standard has been developed within the Technical Committee TETRA of the European Telecommunications Standards Institute as a major upgrade to the existing narrow-band ETSI TETRA system to supply professional users with high-speed IP packet data services over wireless mobile channels. Multicarrier-based modulation format, powerful payload and header encoding and link adaptation methods are among techniques employed for this purpose. The above enhancements are efficiently combined with improved higher layer protocols enabling a number of new services such as multiple multimedia access with QoS re-negotiation during the session, various priority mechanisms, provision of scheduled access for delay-sensitive applications and support for sectored antenna usage. The aim of this paper is to give a comprehensive overview of the TEDS features with particular emphasis on the physical layer and medium access control features together with representative link and system performance results.

Abstract

The TETRA enhanced data service (TEDS) standard has been developed within the Technical Committee TETRA of the European Telecommunications Standards Institute as a major upgrade to the existing narrow-band ETSI TETRA system to supply professional users with high-speed IP packet data services over wireless mobile channels. Multicarrier-based modulation format, powerful payload and header encoding and link adaptation methods are among techniques employed for this purpose. The above enhancements are efficiently combined with improved higher layer protocols enabling a number of new services such as multiple multimedia access with QoS re-negotiation during the session, various priority mechanisms, provision of scheduled access for delay-sensitive applications and support for sectored antenna usage. The aim of this paper is to give a comprehensive overview of the TEDS features with particular emphasis on the physical layer and medium access control features together with representative link and system performance results.
