Broadcom Launches Second-Generation Wi-Fi 7 Wireless Connectivity Solution

Last year, Broadcom made a splash with its first-gen Wi-Fi 7 chips, and now they’re back with a bang, launching their second-generation Wi-Fi 7 wireless connectivity solutions. Covering Wi-Fi routers for both home and enterprise use, as well as client devices, these new chips promise to deliver blistering speeds and improved integration for the IoT market.

So, what’s new with Broadcom’s second-gen chips? Meet the BCM6765, BCM47722, and BCM4390. These chips are designed to cater to residential and commercial Wi-Fi platforms, supporting the 2.4GHz, 5GHz, and 6GHz frequency bands with Dual 2×2 support and transfer rates of up to a whopping 8.64 Gbps. The enterprise-focused BCM47722 also includes Bluetooth and Zigbee/802.15.4 support to address IoT requirements. Both platforms come equipped with quad-core ARMv8 CPUs and 10G PHY.

The client solution, BCM4390, replaces last year’s BCM4398 and supports the 2.4GHz and 5GHz or 6GHz frequency bands. Although channel widths have decreased from 320 MHz to 160 MHz, the PHY rate still reaches an impressive 3.2 Gbps. The BCM4390 also integrates Bluetooth Denver, Thread, and Zigbee support while featuring Broadcom’s proprietary SpeedBooster technology.

Broadcom has already started providing samples of its second-gen Wi-Fi 7 chips to retail, enterprise, and other customers. There’s key features of these new chips.
