December 2002 - Ericsson
and AT&T Wireless completed the first WCDMA/UMTS call
in a live network environment in the Americas. With
initial packet data speeds up to 384 kbps, the call
demonstrates true 3G capabilities, which include quick
downloads of such bandwidth-demanding applications as
E-mail with attachments and streaming audio and video.
The
joint effort is part of a trial of the first 1900 MHz
UMTS/WCDMA system in the Americas, which will have more
than 100 cell sites in the Dallas area by the end of
the year. Ericsson is providing the complete WCDMA/UMTS
network -- the core network, the radio access network
and mobile terminals. The small-sized Sony Ericsson
test units used are based on technology developed by
Ericsson Mobile Platforms.
"We
will continue moving forward in our quest to provide
customers with the most advanced wireless services in
the world," said Rod Nelson, chief technology officer
for AT&T Wireless. "There is a tremendous level of support
by vendors, carriers and developers in bringing true
3G service to the United States."
"It's
really exciting to take what we've learned from our
laboratory trials and apply those lessons to a live
network environment," said Angel Ruiz, president and
chief executive officer, Ericsson Inc. "In other parts
of the world, we've seen live tests before in the 2
GHz band. But this is a landmark in the development
of UMTS/WCDMA in the 1900 MHz frequencies and its progress
in the Americas."
This
path ensures a smooth evolution to EDGE, then UMTS,
a wideband radio technology that provides mobile users
with data rates up to 2Mbit/s. The efficient use of
radio spectrum enables simultaneous access to everything
from regular voice telephony to a range of content-rich,
multimedia services. For example, users will be able
to watch a video clip while receiving an e-mail. The
UMTS solution also enables a mix of circuit and packet
services, with varying bandwidths to be delivered at
the same time.
