Intersil, largest maker of 802.11b chipsets, announces its 802.11a, 54 Mbps plans and availability: Although Intersil doesn't expect to ship in quantity to manufacturers until after fourth quarter 2001, it's good to know they're on track. Atheros, another chipmaker, has aggressively pushed its own 802.11a chipset. But Intersil's announcement broadens the industry impact. Intersil reiterates in this press release their support for the OFDM modulation that's employed in 802.11a to also be used in 802.11g.
