Broadcom is sampling 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 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.
Broadcom Wi-Fi 7 ecosystem includes
- support for 3-link MLO, which reduces latency by 50% compared to typical 2-link implementations.
- supports for its 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.
- 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.
- support the latest Bluetooth 5.4 standard
- forward-compatibility with the draft Bluetooth Channel Sounding specification for location services, which 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.
“High-speed, low-latency wireless connectivity is essential for our homes and offices alike. We launched a complete Wi-Fi 7 ecosystem for mobile handsets and residential and enterprise networks last year to power the next generation of digital experiences,” said Vijay Nagarajan, vice president of marketing for the Wireless Communications and Connectivity Division at Broadcom. “With these three new products, Broadcom enables its customers to build a diverse set of best-in-class Wi-Fi 7 products across a wide range of markets.”
