Marconi and Nokia take concrete steps in developing truly open multi-vendor networks in TETRA technology

Nice, December 11 2001 - After the TETRA MoU Technical Forum achieved major progress in the development of Inter-System-Interface (ISI) specification in June this year, Marconi and
Nokia, through their Italian consortium Securcomm, have jointly started the practical development of ISI in their TETRA systems.

The consortium, aiming to provide the Italian police with secure and reliable communications services, implements and tests ISI services in both vendors' network infrastructure during 2002. The target is to achieve more than a preliminary interface, but rather a real ISI implementation.

"Nokia enthusiastically continues to support TETRA ISI development. This is an excellent continuation to the TETRA MoU Technical Forum agreement in Helsinki last June, and also fits Nokia's overall commitment to truly open standards for the benefit of all user groups and the industry as a whole. I am convinced the ISI development we have begun is a significant cornerstone for the success of the evolution of public safety communication services," said Kari Suneli, Senior Vice President, Nokia Networks.

"Since the beginning of TETRA , Marconi has always been committed to its development as an open standard, suitable for a multi-vendor market. Implementing ISI represents the key to reaching that goal. In this perspective, our co-operation with Nokia started 18 months ago with the Securcomm Consortium and is now in an advanced stage. The consortium is perfectly in line with our strategy and the philosophy of the TETRA standard," stated Luciano Maciotta -EVP, Marconi Private Mobile Networks unit.

Marconi plc has research and development facilities in 19 countries, manufacturing operations in 16 countries, and serves customers in over 100 countries, delivering innovative solutions that transform communications networks. Marconi plc is listed on the London Stock Exchange and Nasdaq under the symbol MONI.

Nokia is the world leader in mobile communications. Backed by its experience, innovation, user-friendliness and secure solutions, the company has become the leading supplier of mobile phones and a leading supplier of mobile, fixed broadband and IP networks. By adding mobility to the Internet Nokia creates new opportunities for companies and further enriches the daily lives of people. Nokia is a broadly held company with listings on six major exchanges.
