Welcome Message of TESS' CEO

Communication is one of the easiest ways to interact with people. Communication - by whatever means - builds trust and what is probably most important - nowadays we are able to exchange all kind of information - orally, in written and by pictures. Effective communication is an essential component of organizational success whether it is at the interpersonal, intergroup, intragroup, organizational, or external levels.
Welcome to T.E.S.S.. Welcome to the world of professional mobile radio communication - one way to interact with people - the way T.E.S.S. will support you with.
Organizations are influenced by the technology available to them. This affects how they assign different functions to different staff and how they design their working processes.

The network we can offer you is a TETRA network (Terrestrial Trunked Radio), developed in accordance with the specifications of the European Telecommunication Standards Institute (ETSI). TETRA is a terrestrial trunked radio system which has been system-engineered specifically for the field known as PMR (Professional Mobile Radio) where mission critical applications with high requirements in respect of the availability and reliability of the technology employed are common. This user group includes public safety organizations, the transport and traffic sectors, utilities and large industrial sites.
