Broadcom Corp. has introduced an 802.11g Wi-Fi chip that integrates its 54g radio and a MAC block with an Ethernet switch and a MIPS processor, providing full Layer 3 routing.

The company also has announced design wins with Lenovo for 802.11n and with Buffalo Inc. for phones" target=_blank>Skype Wi-Fi phones.

The BCM5354, meeting legacy b/g standards at 2.4GHz, indicates that Broadcom will continue to integrate existing Wi-Fi designs even as it rolls out 802.11n products. The CMOS chip integrates a USB 2.0 port as well as an Ethernet switch, and it can create and access multiple networks through a single access point via multi-BSSID software.

Meanwhile, Broadcom's Intensi-fi 802.11n chipsets will be integrated into Lenovo's N100 widescreen notebook computer and selected 3000-family notebook computers. The computers will use the Broadcom chips to access dual-band 802.11a/g/n services and will integrate Bluetooth and Ethernet capabilities.

Broadcom's Wi-Fi phone reference design will be used by Buffalo to provide embedded support for Skype VoIP phone calls. The Skype-certified Buffalo phone will be ready for sale in the Japanese market this month.

Broadcom's reference design, combining the BCM1161 VoIP processor and the AirForce One BCM4318E 54g chip, will support Skype software for other OEMs as well.
