The new AirPlus Xtreme line from D-Link is the first announced product set that will use Intersil's 802.11g-draft compliant chipset.

Irvine, CA-based D-Link has announced its first 802.11g-draft compliant products, AirPlus Xtreme G DI-624 Wireless Router with 4-Port Switch and the AirPlus Xtreme G DWL-G650 Wireless CardBus Adapter. The products are the first from the company to support the draft standard for 2.4GHz 802.11g-based networks.

The AirPlus Xtreme line are built using the Intersil PRISM GT chipset, which was the first 802.11g draft chipset announced back in January. As the standard will specify when finalized, the PRISM GT builds in two mandatory modulation schemes, Complementary Code Keying (CCK), used in 802.11b, and Orthogonal Frequency Division Multiplexing (OFDM), which is currently used in 802.11a networks (which, like 11g, runs at 54Mbps).

Intersil previously told 802.11 Planet that full production of PRISM GT would begin in the first months of 2003; it has been sampling with customers for a few weeks. By supporting 802.11g, the PRISM GT also supports 802.11b, as the two are compatible.

The D-Link AirPlus Xtreme router has a built in 4-port 10/100Mbps Ethernet switch; Dynamic Host Configuration Protocol (DHCP) server for dolling out IP addresses to client systems; security including stateful packet inspection, MAC address authentication content filtering, and parental controls; and omni-directional antennas that can be detached; all for a manufacturer's suggested price of $149.99. The $79.99 32-bit PC Card adapter has a low-profile internal antenna. Both products support Wired Equivalent Privacy (WEP) encryption up to 128-bit and have three year warranties.

While the first company with PRISM GT chips inside, D-Link is not the first out with an 802.11g-based solution. Buffalo Technology, Belkin, Linksys and others have announced or even shipped products using Broadcom's g54 chipset which also supports the 11g specification draft. The finalized specification for 802.11g is expected sometime in 2003.
