UMTS ImplementationsUMTS has already been implemented in Japan, who has launched the first commercial network using WCDMA access technologies in 2001. Since then, WCDMA networks have appeared in Austria, Italy, Sweden and the UK. More launches are anticipated in the near future. 200 operators around the world are offering 2.5G standards, based on GPRS, which paves the way for 3G systems.
Many operators are also advancing plans to deploy EDGE technology to increase the speed and capacity of mobile services offered in their current GSM frequency allocations.
With the 3G licensing process largely completed in many parts of the world, WCDMA networks at an advanced stage of construction in many countries and handsets becoming available from an increasing number of manufacturers, the stage is set for the worldwide deployment of UMTS systems.
