Broadcom has launched three new Wi-Fi 8 access point SoCs: the BCM6772 for mass-market Ethernet routers, extenders, and repeaters, the BCM6774 for high-volume Ethernet routers and extenders, and the BCM6776 for premium Ethernet tri-band routers and extenders. The latter is also part of a 5G FWA router platform based on Samsung B1320 5G Modem.
Broadcom’s first Wi-Fi 8 chips were introduced in May 2025 for clients and access points, and the company followed up with BCM6714 and BCM6719 dual-band radios earlier this year, and the BCM67142, BCM67192, and BCM68565 chips for low-cost Wi-Fi 8 10 Gbps fiber access points last month. So far, all the Broadcom Wi-Fi 8 chips enable multi-chip solutions with an application processor connected to one or more Wi-Fi 8 chipsets over a PCIe connection. The new BCM677x chips are fully-integrated SoCs with (Armv8>) application cores and 802.11bn connectivity in a single chip, except for 6 GHz Wi-Fi 8, as we’ll see further below.

5G and Wi-Fi 8 FWA Platform
The Broadcom BCM6776 SoC is also part of the 5G and Wi-Fi 8 FWA (Fixed Wireless Access) router reference platform developed in collaboration with Samsung. Besides the tri-band WiFi 8 solution, it also features Samsung’s B1320 broadband-optimized 5G platform with the following highlights:
- CPU – 1.6 GHz quad-core ARM Cortex-A55 CPU
- Memory – LPDDR4x / LPDDR5x support
- Cellular
- 3GPP Release 17
- 4Rx/2Tx radio chain support
- Power Class 1.5 support (TDD bands)
- 5G NR-NTN and NB-NTN satellite support for n255 and n256 (L- and S-bands)
- GNSS
- Networking – 5 Gbps USXGMII
- Host interfaces – PCIe Gen 3, USB 2.0
HUMAX Networks is one of the first companies to develop a 5G CPE based on the solution.
Broadcom is currently sampling the BCM677x Wi-Fi 8 family to early access partners and customers, while the Samsung B1320 / Broadcom BCM6776 FWA platform is sampling to OEM partners. More details about the BCM677x family can be found on the Broadcom website. There’s no product page for the 5G FWA reference platform, and it was just introduced through a press release.
