James Bond: Do you expect me to talk?
Auric Goldfinger: No, Mr. Bond. I expect you to die.
HSDPA provides the Grand Slam in wireless mobility, says 3G Newsroom:
Led by Cingular Wireless in the U.S., operators worldwide are about to start deploying High Speed Downlink Packet Access (HSDPA), one of the most powerful cellular-data technologies ever developed. 3G Americas published a white paper (pdf), prepared by independent wireless consultant Peter Rysavy of Rysavy Research, which examines the performance of the GSM family of data technologies — GPRS, EDGE and UMTS/HSDPA — how they work, and their position relative to some competing technologies.
HSDPA, an enhancement to UMTS for packet data, delivers average data throughput rates to the subscriber of 550-1100 Kbps and peak theoretical rates of 14 Mbps. The paper also reconfirms that HSDPA with its enhanced features could increase spectral efficiency by a factor of 2.5 — 3.5x when operators complete an upgrade of their UMTS networks.
Some of the key observations and conclusions of the paper include:
- UMTS/HSDPA represents tremendous radio innovation and capability, allowing it to support a wide variety of applications, including voice and data on the same devices.
- Various enhancements are planned for HSDPA that will extend UMTS/HSDPA capability even further, beginning with an enhanced uplink (HSUPA), advanced receivers and then intelligent antennas/MIMO.
- OFDM is a good candidate technology for next generation systems employing wide radio channels. However, it does not offer compelling advantages over UMTS in radio channels of 10 MHz or less. Initial versions of IEEE 802.16e are likely to have spectral efficiency similar to HSDPA.
- Ongoing UMTS evolution includes significant enhancements with each new specification release, including higher throughput rates, enhanced multimedia support, and integration with wireless local area network WLAN) technology.
“The GPRS to HSDPA evolution provides one of the most robust technology portfolios and an optimum framework for realizing the inevitable mass market potential for mobile wireless data,” confirmed the paper’s author Peter Rysavy.
Of course the EV-DO camp, the WiMax camp, and the Qualcomm/Flarion camp may beg to differ.
