Broadcom, Atheros and Marvell were quick to usher out press releases announcing their full support for the 802.11n draft standard. Broadcom's Intensi-fi family of WLAN chipsets along with Marvell's 88W836X family will be firmware upgradeable to support changes made to the draft standard during the qualification phase. Both will also be upgradeable to the final 802.11n standard which is expected to be ratified within the next year.
The dual-band 2.4GHz/5.8GHz 802.11n draft brought forth by the EWC support interoperability with all 802.11a/b/g networks. Wireless devices will support one to four antennas to allow simultaneous transmissions at speeds up to 600Mbps. Users are expected to see at least 100Mbps of bandwidth at the application level.
