Broadcom has announced sample availability of its second generation of wireless connectivity chipset solutions for the Wi-Fi 7 ecosystem, spanning Wi-Fi routers, residential gateways, enterprise access points, and client devices. The new chips build on the ecosystem of Wi-Fi 7 products with Broadcom’s first-generation Wi-Fi 7 chips while delivering additional functionality to a wider market.
The first chip, the BCM6765, is a highly optimized residential access point chip that supports 320 MHz 2-stream Wi-Fi operation. This new platform system-on-chip (SoC) allows the productization of Wi-Fi 7 mass-market access points and smart repeater solutions which span the spectrum of cost, form factor, and performance. The second chip, the BCM47722, is an enterprise access point chip that also supports 320 MHz 2-stream operation along with dual IOT radios that support simultaneous operation for Bluetooth Low Energy (BLE), Zigbee, Thread, and Matter protocols. This SoC addresses the growing needs of Internet of Things (IoT) applications in the enterprise Wi-Fi market. The third chip, the BCM4390, is a low-power Wi-Fi, Bluetooth, and 802.15.4 combo chip designed for use in mobile devices such as handsets and tablets. It supports 160 MHz 2-stream Wi-Fi operation, dual Bluetooth, and Zigbee, Thread, and Matter protocols to service a broad set of mobile markets.
Wi-Fi 7 is designed from the ground up for the newly available 6 GHz band and brings multi-gigabit wireless broadband to your homes and hands. Wi-Fi 7 devices based on Broadcom’s first-generation products have already reached the market, and the second-generation of chips announced today builds on this momentum to significantly expand the range of products using Wi-Fi 7 wireless connectivity.
Wi-Fi 7 will experience rapid adoption, driven by both increased bandwidths, and by Wi-Fi 7 multi-link operation (MLO), which allows devices to aggregate channels and rapidly switch between channels. This is an ideal feature for high-density and congested networks and guarantees commercial-grade quality of service and optimal application latency. Broadcom’s Wi-Fi 7 ecosystem includes support for 3-link MLO, which reduces latency by 50% compared to typical 2-link implementations. Wi-Fi 7 will also use Automatic Frequency Coordination (AFC) for optimal spectrum allocation to enable high-power access points and extend 6-GHz transmit range in both indoor and outdoor environments. In addition, Broadcom Wi-Fi 7 supports the proprietary SpeedBooster feature, which allows 160 MHz devices, such as mobile devices based on the BCM4390, to use the full 320 MHz access point capacity, thereby doubling Wi-Fi connection speed. In all, Broadcom Wi-Fi 7 delivers fast, high-quality video streaming and more responsive gaming, and improves other applications that require reliable speeds in congested environments.
Additionally, both the BCM47722 and BCM4390 support the latest Bluetooth 5.4 standard and are forward-compatible with the draft Bluetooth Channel Sounding specification for location services. This brings a wide range of new features both to mobile handsets, such as secure vehicle keyless entry, and enterprise access points, including support for asset tracking and electronic shelf labels. In addition, both chips support Zigbee, Thread, and Matter, allowing them to interoperate with the growing number of residential and enterprise IoT devices.
“A year ago, Broadcom announced a complete Wi-Fi 7 ecosystem for mobile handsets and residential and enterprise networks,” said Vijay Nagarajan, vice president of marketing for the Wireless Communications and Connectivity Division at Broadcom. “With the addition of these three new products, Broadcom enables its customers to build a diverse set of high-performance Wi-Fi 7 products across a wide range of markets.”
“Device capabilities continue to evolve and expand, and at the same time, new services and applications are arriving that require cloud, edge, and on-device processing,” said Phil Solis, research director for connectivity and smartphone semiconductors at IDC. “Wi-Fi 7 and MLO are rapidly becoming a must in new devices and access points, and Bluetooth LE Audio, Bluetooth Channel Sounding, Zigbee, and Thread round off support for new features and Matter.”
“Wi-Fi 7 revenue for both the Consumer Wi-Fi Infrastructure and Enterprise Access Point markets will exceed that of any other Wi-Fi technology in five years, mostly coming from Wi-Fi systems based on 6 GHz devices,” said Chris DePuy, technology analyst at 650 Group. “Additionally, we expect that IoT device shipments will grow at over 50% CAGR in the Enterprise market in the next several years. Therefore, Broadcom's support for Bluetooth, Zigbee, and other wireless interfaces is critical.”
