Broadcom Expands Wi-Fi Chip Portfolio

Broadcom announced three additions to its wireless LAN product portfolio: 802.11g and 802.11a/g USB 2.0 adapters, and a new wireless networking processor for secure 802.11a/g enterprise access point and router applications. Broadcom said the USB interface gives users the ability to easily add standards-compliant 802.11g and 802.11a/g to desktop systems without removing the PC chassis cover. USB 2.0 technology delivers 480 Mbps of bandwidth, which is necessary to support 54 Mbps wireless connections, while legacy USB 1.1 systems are capable of only 12 Mbps.


Broadcom's new network processor is the next-generation of its BCM4702 chip, which it describes as the most popular wireless network processor in the industry. The new model adds a network processing core that is capable of wire-speed Ethernet routing/bridging, as well as VPN termination on an integrated IPSec security acceleration engine.
