Nokia Advances New Technology for Dense GSM Networks
July 27, 1998
Nokia is pioneering the development of an innovative technology to help operators increase capacity in high-traffic mobile telecommunications networks. Operating on the 58 GHz frequency band, this unique solution will change the economies of building dense access transmission networks, particularly in urban and heavily populated areas.
As an established leader in cellular transmission, Nokia has continuously responded to mobile traffic needs by introducing innovative, cost-effective base station subsystem features and solutions to help operators meet more demanding capacity requirements. As the number of subscribers to mobile services continues to increase, the ability to create high-density access will have a significant impact throughout the industry.
The new technology makes use of the 58 GHz frequency band, which allows very high reuse of the same frequency without signal interference. This means hundreds of transmission links can be established per square kilometre. Also, because the band does not require co-ordinated frequency planning, the link connection lead time is significantly reduced. In addition to saving time, operators will also save money on the access link connection because this self-regulating band is likely to have a substantially smaller annual fee.
"There is an understanding throughout the telecommunications industry that affordable methods of building capacity and high-density access in GSM networks need to be explored," explains Mr Olli Oittinen, Vice President, System Marketing and Sales, Radio Access Systems, Nokia Telecommunications. "This technology will allow unprecedented capacity coupled with reliable network quality."
Nokia's innovative high-density access technology is based on proven microwave transmission. Nokia will introduce new products which make use of this technology during 1998, lowering the lifetime cost of an access network to a completely new level.
Nokia is a broad-scope communications company supplying mobile phones, mobile and fixed telecommunications networks, wireless data communications solutions, multimedia terminals and computer monitors. In 1997, net sales totaled FIM 52.6 billion ($9.8 billion). Headquartered in Finland, Nokia is listed on the NYSE (NOK.A), has sales in 130 countries and employs more than 41,000 people worldwide.

Notes to Editors:
As links become shorter in dense areas, frequency planning can be extremely difficult due to the complexity of synchronising the transmission connection with base station installation. However, Nokia's new technology uses the 58 GHz frequency band, which does not require co-ordinated frequency planning. Therefore, the link connection lead time is significantly reduced, allowing practically same-day transmission connection to the base station.
Recommendations for use of the 58 GHz frequency band recently have been revised by the European Conference of Postal and Telecommunications Administrations (CEPT) to include a simple etiquette that identifies existing transmission during initial allocation of the radio relay channels. This function can be conducted automatically with the Nokia access
