Nokia and Helsinki City Energy Company Agreed on TETRA Development Project
January 22, 1997
Nokia Telecommunications and Helsinki City Energy Company have signed an agreement for a development project based on a digital TETRA system. The development project will define and test data services in the TETRA system and demonstrate in practice the versatility and efficiency of the data services connected to the TETRA system.
Helsinki City Energy Company will use Nokia’s TETRA system to improve its data and speech communication. Optimised data connections in vehicles give new possibilities to improve operations of Helsinki City Energy Company. With development co-operation the parties aim to advanced utilisation of the new services provided by the new technology.
Nokia will deliver to the Helsinki City Energy Company a complete TETRA system including a switching centre, base stations, network management system and antennas. The deliveries will begin in April 1997 and the network will be taken into operation in the beginning of 1998.
Trans European Trunked Radio (TETRA) is a new open digital trunked radio standard defined by the European Telecommunications Standard Institute ETSI to meet the needs of the most demanding professional mobile radio users such as utility- and oil companies, railways and authorities. A large group of European user- and manufacturer-organisations have participated in the definition of the standard. The TETRA Memorandum of Understanding (MoU) was established in December 1994, as a forum to represent the interests of all parties in TETRA, including users, manufacturers, operators, test houses and telecom agencies. Today the TETRA MoU represents 58 companies from 14 countries world-wide. According to estimates, TETRA-based systems will have 5-10 million users by year 2010.
Nokia is continuing to develop its TETRA system. Delivery capability will include complete systems encompassing exchanges, base stations, terminals, network management centres and dispatcher stations. Nokia has been developing TETRA almost 10 years. Nokia has delivered its Actionet trunked radio systems based upon the open MPT 1327 analogue trunking standard to over 30 countries in Europe, Asia and Australia.
