7th November - Ericsson passed an important
milestone last week when it successfully upgraded Vodafone
K.K.'s commercial network in central parts of Tokyo to support
High Speed Downlink Packet Access (HSDPA), as specified in
Release 5 of the 3GPP standard, in order to test HSDPA with
Vodafone K.K.'s live network.
The software and hardware in the HSDPA-enabled
base stations supports downlink bit-rates up to 3.6 Mbps and
uplink rates up to 384 Kbps; however, this capability has
not been enabled for Vodafone K.K. customers at this time.
The hardware and software upgrades of the first
commercial network sites represents a major milestone in the
program to offer HSDPA and is the latest in a series of achievements
in the HSDPA area between Vodafone K.K. and Ericsson.
The two companies have been jointly performing
lab trials of pre-commercial HSDPA equipment since September
2004 and field trials have been continuing since early 2005.
These tests have been used to build competence and experience
about HSDPA radio network performance, as well as end-user
application behaviors in different radio environments.
