Electcoms, Malaysia's leading trunking radio and radio-paging operator, has 400 MHz MPT and 800 MHz analogue trunking systems. These trunking systems principally cover the key areas of the economically developed West Malaysia with a capacit...

Terrestrial Trunked Radio[1] (TETRA) (formerly known as Trans-European Trunked Radio) is a professional mobile radio[2] and two-way transceiver (colloquially known as a walkie talkie) specification. TETRA was specifically designed for use b...

TETRA is an open standard developed by the European Telecommunications Standards Institute (ETSI). The main purpose of the TETRA standard was to define a series of open interfaces, as well as services and facilities, in sufficient detail t...

The original TETRA standardfirst envisaged in ETSI was known as the TETRA Voiceplus Data (V+D) standard. Because of the need to further evolve and enhance TETRA, the original V+D standard is now known asTETRA Release 1.An overview of the n...

To meet the needs of traditional PMR user organisations, a wide range of V+D services and facilities have been provided in the standard, of which the most important are considered to be: Voice Services Group Call (commonly called all infor...

DMO is the term used by the TETRA industry to describe the ability of TETRA radio terminals to communicate directly with each other (like Walkie-Talkies) independent of the Trunked Mode Operation (TMO) network. DMO is not new and has been...

This is a completed part of the TETRA suite of standards produced for Data Only wireless communication applications.To date, no manufacturer has developed PDO systems and products because all traditional Professional Mobile Radio (PMR) use...

TETRA Release 1 (Voice + Data) already provides a very comprehensive portfolio of services and facilities but as time progresses there is a need to evolve and enhance all technologies to better satisfy user requirements, future proof inves...

The area of TETRA security is extensive, as it needs to provide different levels of security ranging from what is acceptable on commercial networks to what is acceptable on a national public safety network. The security mechanismsin the st...

The core technologies used in the TETRA standard, such as Digital, Trunking and Time Division Multiple Access (TDMA) also provide a number of inherent advantages and benefits as follows: Digital Nowadays, practically everything electronic...
