TI Speeds Up D-Link's 802.11g

The networking equipment maker will use TI's chipset with packet-bursting technology in a new line of 802.11g products.

Wireless gear maker D-Link Wednesday announced a new family of products based on Texas Instruments' 802.11g chips.

The Irvine, Calif.-based company said it will use TI's TNETW1130 chipset with packet-bursting technology in its new AirPlus XtremeG+ line. The chipset features a turbo mode that TI says delivers speeds up to 30Mbps, or around eight times greater than average 802.11b throughputs.

The chip leverages techniques from the upcoming 802.11e specification such as packet aggregation, according to Remi El-Ouazzane, a marketing director at TI. By adjusting the contention window, he said, "we were able to be a bit more aggressive with regards to network access time. You can send more packets in an equivalent amount of time, allowing you to increase throughput."

The AirPlus XtremeG+ line, which will include a wireless access point (DWL-G2000AP), 32-bit cardbus adapter (DWL-G650+) and a 32-bit PCI adapter (DWL-G520+), will be available late in the third quarter in Europe and Asia. Pricing was not available. A D-Link representative said that there are no plans to introduce the products in the United States.

D-Link is also using chipsets from Intersil and Atheros in its 802.11g products. The company last week unveiled a USB adapter and Ethernet-to-Wireless Bridge using Intersil's Prism GT chips. Meanwhile, Atheros said earlier this week that it will supply its 802.11a/b/g chips for D-Link's routers, access points and adapters in the U.S. market.

In a separate announcement today, D-Link said that it has released new firmware for its AirPlus Xtreme G products that supports the final 802.11g specification, which was ratified by the IEEE in June.
