US
: 3G Americas published a white paper, prepared by independent wireless
consultant Peter Rysavy of Rysavy Research, confirming previously
reported commercial network results on EDGE and UMTS data performance.
The white paper, Data Capabilities: GPRS to HSDPA showcases new research
on High Speed Downlink Packet Access (HSDPA), an enhancement to UMTS
for packet data that delivers average data throughput rates of 550-1100
kbps and peak theoretical rates of 14 Mbps. The paper also confirms
that HSDPA with its enhanced features could increase spectral efficiency
by a factor of 2.5 to 3.5 when operators complete a simple upgrade
of their UMTS networks, much as they did with their GPRS networks
when supporting EDGE.
"EDGE and
UMTS have made significant progress in the past eighteen months, with
each of these technologies in various stages of readiness to deploy
by more than 100 operators. Today, commercial UMTS services are available
in six major U.S. cities, while globally UMTS is commercially available
on 46 networks in 24 countries," Chris Pearson, President of
3G Americas stated. "The Rysavy Research paper validates what
has been accomplished with EDGE, currently hitting the 'sweet spot'
of data users at 100-plus kbps, and also explains the characteristics
of UMTS today, and what's to be expected in the near future with UMTS
- HSDPA."
"The GPRS,
EDGE, UMTS and HSDPA family of wireless data technologies provides
an extraordinary evolution in capability that will allow cellular
networks to support the most demanding data applications, whether
consumer or enterprise oriented," advised Peter Rysavy. "These
advancing capabilities encompass not only larger increases in the
average and peak data throughputs, but also an increase in capacity
through a much higher spectral efficiency and a significantly reduced
latency."
Some of the key
observations and conclusions of the paper include:
Actual results
from the field that show throughput rates nearly identical to the
predictions previously outlined in the Rysavy Research-prepared 3G
Americas' white paper Data Capabilities: GSM Evolution to UMTS published
in 2002. EDGE more than triples GPRS data throughputs, delivering
typical rates of 100-130 kbps.
UMTS is spectrally efficient for high-data throughput services, offering
average data rates of 220-320 kbps and very low latency.
UMTS ? HSDPA is expected to provide average speeds of 550-1100 kbps,
with even lower latency than UMTS.
Globally, there is accelerating momentum in the deployment of EDGE
and UMTS as complementary 3G technologies.
Operators deploying the GSM family of technologies (GSM/GPRS/EDGE/UMTS/HSDPA)
can efficiently use their available spectrum resources for both voice
and data services simultaneously.
