Hong Kong Police, Hong Kong

Key Data

In November 1999, Nokia was awarded a contract to supply a Nokia TETRA professional mobile radio network to the Hong Kong police. The contract is valued at over $18 million and the whole system went fully operational in October 2000.

In December 2001 Nokia signed another contract with the Hong Kong Fire Services Department to provide a wireless digital network (WDN) TETRA system. The new contract will cover base stations, equipment and network management.

Nokia is considered one of the world's leading mobile phone suppliers. Its headquarters are in Helsinki, Finland.


Nokia, along with other large manufacturers, have developed new digital trunking systems according to the TETRA standard. Trans European trunked radio access system (TETRA) is a new global digital trunked radio standard. This standard is defined by the European Telecommunications Standards Institute (ETSI). Although developed in Europe, ETSI standards have been widely applied worldwide.

Digital trunking is considered the leading professional mobile radio technology, bringing with it the advantages of in-built encryption, high speed data, spectrum efficiency and scanning features; all well suited to demanding public safety and security user needs. Most European countries are today in the process of planning digital trunked radio networks for their police forces.

The development of the TETRA system has been based on experience in digital radio communications. The original Nokia TETRA system was available in 1997, and had six years of research and development behind it to meet the most demanding user requirements.

The application of TETRA for the police force and Fire Department in Hong Kong strengthens the position of the TETRA standard in Asia Pacific and China. The Hong Kong police force are now one of the most highly technologically advanced. This is especially true as new applications are added for access to databases, and WAP over TETRA IP.


The system infrastructure consists of TETRA digital exchanges (DXT), TETRA base stations (TBS) and TETRA dispatcher workstations (DWS), as well as network management centres (NMC). Exchanges and base stations are scaleable in size to cost-effectively meet various capacity needs. This infrastructure is supported by an extensive set of mobile and hand-held radio terminals and accessories (from rugged full function models to feature rich system radios). The modular Nokia TETRA mobile radio can be equipped with different types of control units to meet various user interface and environmental requirements.

The agreement with the Hong Kong police forces includes five sub-systems: the transport network, marine voice, automatic vessel location, messaging and crime units sub systems. The contract covers a complete Nokia TETRA system including digital exchange, base stations, dispatching equipment, network management system, terminals, and related customer services, including system integration. The infrastructure is supported by Nokia's mobile and hand portable radio terminals and accessories.


The key benefits of Nokia TETRA systems are that the Hong Kong police will have more radio channels with less congestion, an improved personal and group communication system, better efficiency and safety and encryption (complete security of communication). The voice communication is easier than with a conventional radio system. Users will not have to think about base stations, channels or where the other radio users are in the network. All this is handled automatically by the network and all radio communication can be encrypted by the system. TETRA radios can be used to communicate in areas outside network coverage, in a tunnel for example. Users will also need to exchange data, such as instructions, addresses or map references. In this case the same radio terminal can be used for both voice and data communication, even at the same time.
