Europe Portugal : The International 450 Association (IA450) announces its support of dual band CDMA2000 (IMT-MC) in 450Mhz and 2100MHz bands as a superior option for operators looking to expand network capacity and at the same time maintain strong coverage in low population density areas. Vadim Belyavskiy, IA450 Board Member, Technical Development Director, Moscow Cellular Communications, Skylink (Russia) and Piermario Di Pietro, CEO, Telemobil (Zapp Romania) set out the advantages of network operations in CDMA450 & 2100 MHz band at INFORMA's 450 MHz Digitalization Conference, recently held in Lisbon, Portugal.

Both of them covered the advantages of the dual band solution including comprehensive coverage, low capital expense and synergies between the bands. While the 450 MHz band provides unmatched coverage due to better signal propagation at lower frequencies, 2100 MHz band delivers capacity in hot spots with high traffic demand.

Radio interfaces of the networks in the 2100 and 450 MHz frequency bands are based on the IMT2000 IMT MultiCarrier standard with identical protocols and features. 2100 and 450 BTS may share the same base station controller, core network infrastructure and services platforms thus minimizing the capex required to roll-out the dual-band network. Full support of inter-band interoperability was proved in the trial networks rolled out in Moscow and St.Petersburg as reported by Mr.Belyavsky.

IMT-MC 450/2100 networks offer an attractive solution from both a technical and economic standpoint. Dual band IMT-MC 450/2100 networks are a flexible and cost-effective solution for providing 3G services in cities and rural areas.
