December 2002 - Nokia
and Radiolinja, the Finnish mobile operator, have successfully
demonstrated Service Area Identity (SAI) positioning
technology as part of the Nokia mPosition solution.
The field trials were carried out using Radiolinja's
"pre commercial" WCDMA network and achieved good results
in accurately determining a user's position within the
range of a single network cell.
The
field trials were carried out in a combined urban and
suburban area in Tampere, Finland. Most tests were carried
out in a moving vehicle.
"The
field trial of 3G location-based services now realized
is a natural continuation of the co-operation Radiolinja
has done with Nokia," says Ari Asikainen, Chief Executive
Office, Radiolinja Origo Oy. "The experience we have
gained now helps us to smoothly move the 2G location-based
services to the 3G network, so that end-users don't
perceive any difference in service."
"Nokia,
in good cooperation with Radiolinja has demonstrated
its WCDMA location capabilities," says Heikki Hemmi,
General Manager, Location Business Program, Nokia Networks.
"This is an important step in showing the smooth evolution
path of location services from 2G to 3G in practice."
Service
Area Identity is an advanced position technology used
in WCDMA networks to determine the physical location
of a mobile subscriber, thus enabling location-relevant
services which are one of the key elements in the Mobile
Internet. Deployment of SAI positioning can be made
with minimum additional network investment because the
GSM and WCDMA network architectures can use the same
positioning calculation and Gateway Mobile Location
servers. There is virtually no cost burden for terminals
either, since SAI does not require any support from
terminals.
The Nokia mPosition SAI solution demonstrated in these
field trials has a smooth evolution path towards the
3GPP standard based CI+RTT and A-GPS (Assisted Global
Positioning System) enhanced positioning technologies
also used in WCDMA networks.
