ASIA
: 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 networkperformance, as well as end-user application
behaviors in different radio environments.
