WLAN chipset market will soar from just over 140 mln annual chipset unit shipments in 2005 to 430 mln in 2009. In 2005, growth was driven primarily by mobile PCs, home/SOHO wireless routers and residential gateways, and external clients, Research and Markets says. Broadcom, Atheros, and Intel were the market leaders in 2005, each ruling specific market segments. In 2007 and 2008, the phone segment will noticeably emerge, driven by embedded Wi-Fi in cellular phones. In 2005, overall chipset revenues were expected to reach almost $1 bln.
