During last years modern telecommunication systems have achieved important results in terms of reliability, coverage and data rate, allowing a high variety of applications services. Among others, TETRA (Terrestrial Trunked Radio) is one of the most important in the professional market; in particular, the DMO (Direct Mode Operation) mode allows half-duplex direct communications among users without the need of an infrastructure.

The idea behind our proposal is an integration between TETRA-DMO and another more flexible wireless system (e.g., IEEE 802.11), where the TETRA-DMO is the access technology, thus allowing the use of standard TETRA-DMO terminals, while the IEEE 802.11 technology can be used as a flexible multi-hop meshed backbone technology for interconnecting remote TETRA-DMO areas.

Abstract

During last years modern telecommunication systems have achieved important results in terms of reliability, coverage and data rate, allowing a high variety of applications services. Among others, TETRA (Terrestrial Trunked Radio) is one of the most important in the professional market; in particular, the DMO (Direct Mode Operation) mode allows half-duplex direct communications among users without the need of an infrastructure. However, TETRA-DMO cannot perform multi-hop communications, limiting both the coverage and the scalability of the whole network. The idea behind our proposal is an integration between TETRA-DMO and another more flexible wireless system (e.g., IEEE 802.11), where the TETRA-DMO is the access technology, thus allowing the use of standard TETRA-DMO terminals, while the IEEE 802.11 technology can be used as a flexible multi-hop meshed backbone technology for interconnecting remote TETRA-DMO areas.
