MOVING IMAGE COMES TO MOBILE TELEPHONES
The first Finnish hand-held telephones were 1G, analog telephones
such as the NMT system. The second-generation 2G is the GSM
telephone, which most Finns are using to speak with in 2002.
The more advanced form of GSM is the 2.5G, i.e. the GPRS system,
which operates more efficiently on the GSM network. UMTS will
require the construction of a completely new, denser base
station network. UMTS will be able to utilize the earlier
mobile communications networks for the trunk network. The
range of a UMTS base station will be about five kilometres.
The UMTS network will be, at least initially, a network in
densely-populated areas that will be supplemented elsewhere
by the GSM and GPRS network. The advantage with UMTS is that
it will enable greater amounts of data to be transmitted cordlessly.
For example, it will be possible to transmit a moving image
to mobile phones.
Sonera’s UMTS network has been in operation since 1
January 2002 in limited areas in Finland’s four biggest
cities, i.e. Helsinki, Oulu, Tampere and Turku.
In the autumn of 2002 Sonera will be launching its first
third-generation mobile communications service. A wider commercial
launching of the services is timed for 2003, at which time
the various equipment producers have claimed they will be
bringing their first UMTS telephones onto the market.
Actual UMTS networks are not yet being used elsewhere in
the world. Since 2001 Japan has been operating its own third-generation
mobile communications network.
