Lucent Technologies' Bell Labs research unit has unveiled a "turbo decoder" chip which the company claimed, can enable wireless transmission speeds up to 10 times faster than the most advanced mobile networks.

However, Lucent does not plan to release equipment based on the standard that the chips support until 2006. In the meantime, the company plans to offer licences for the technology to other manufacturers.

The chips which, Lucent says, can handle data rates up to 24Mbps, support the still-evolving High Speed Downlink Packet Access (HSDPA) standard for high-speed transmissions.

They will support first-generation HSDPA systems estimated at speeds of 5Mbps to 10Mbps, as well as possible future systems that could go up to 20Mbps, a company statement claimed. Lucent's goal is to create high-performance, low-power components that will prompt manufacturers to pursue faster mobile networks.

Mobile operators have been slow to implement high-speed upgrades. AT&T Wireless Services recently scaled back its 3G mobile network plans, and NTT DoCoMo's 3G service in Japan has attracted only mild consumer interest.

A white paper with technical details about the chip is available at

Although several prototypes of the chip for demonstration systems have been made, no mass production is planned at present.
