In Europe and Japan, for example, the UMTS standard will be implemented through 3G newtorks. This evolution to UMTS starts with the great number of GSM users in the world, then passes through GPRS (2,5G) and EDGE (2,75G). The 3G standard IMT2000 was created by the International Telecommunication Union to join all the networks in the world with the general roaming functionality.
