Lucent’s new high-speed downlink packet access technology will be deployed by Cingular Wireless, as a basis for future VoIP over 3G service, as part of its nationwide UMTS 3G rollout.
Lucent Technologies, Inc (NYSE:LU) today unveiled its High-Speed Downlink Packet Access (HSDPA) technology, software that will introduce ultra high-speed data capabilities to third-generation UMTS (Universal Mobile Telecommunications System) networks. Cingular Wireless is including Lucent’s HSDPA in its nationwide UMTS deployment also announced today.
HSDPA will enable the fastest mobile high-speed data connections available – comparable to DSL or cable modem – on devices including 3G phones as well as laptop computers and PDAs equipped with specially designed wireless modem cards. Lucent is currently working with a variety of terminal partners to ensure the availability of HSDPA-capable devices.
Future upgrades of HSDPA will provide theoretical maximum peak data speeds of up to 14.4 Mbps, up from the 3.6 Mbps of today. The objective is to allow UMTS operators to support high-bandwidth data services such as DVD-quality streaming video, or fast downloads of very large files.
It will also enable operators to support up to six times more users than UMTS in the same spectrum, at substantially higher average data rates, maximizing the use of an operator’s available spectrum and laying the groundwork for operators to introduce VoIP over UMTS, and more advanced multimedia services.
VoIP over 3G gives operators the ability to support a greater number of voice users at a lower cost, in turn helping to ensure that voice can continue to be delivered profitably in the context of ever-declining rates chargeable for voice service.
HSDPA is a standardized upgrade of UMTS, also known as Wideband-CDMA, developed by 3GPP (the 3G Partnership Project), an industry body that is responsible for the establishment of standards for 3G UMTS networks. HSDPA is part of a series of upgrades collectively known as UMTS Release 5.
