Universal
Mobile Telecommunications System is the European element of the global IMT-2000 family
UMTS is
the evolutionary next step from second generation digital mobile systems. It
is expected to have capability well beyond that of GSM, but to be usable in combination
with existing GSM systems on dual band terminals
Roaming across Europe, Japan and other Asian countries
should be possible, with potential for US roaming, subject to development of a common
standard by the standardisation organisations (ETSI, ARIB and T1P1)
