Broadcom introduced a fixed wireless access reference platform with Samsung Electronics that combines Broadcom’s BCM6776 Wi-Fi 8 SoC with Samsung’s B1320 5G modem. The platform targets global FWA gateways and customer premises equipment, pairing 3GPP Release 17 cellular connectivity with the emerging IEEE 802.11bn Wi-Fi 8 standard.
The BCM6776 integrates a quad-core Arm network processor with tri-band Wi-Fi 8 radios, supporting 2-stream 40 MHz operation in 2.4 GHz and 4-stream 160 MHz operation in the 5 GHz and 6 GHz bands. Broadcom said the single-chip approach reduces board complexity, lowers bill-of-materials cost, and cuts active power consumption by 50% compared with previous generations.
Samsung’s B1320 modem uses a 5nm design and supports downlink speeds up to 3.43 Gbps and uplink speeds up to 1.17 Gbps. The platform also includes Power Class 1.5 RF, GNSS, NR-NTN and NB-NTN satellite communications support, and interfaces including 5 Gbps USXGMII, PCIe Gen 3, and USB 2.0. Global carrier trials and OEM sampling are underway, with HUMAX Networks and WNC among the OEMs integrating the platform into gateway portfolios.
- Platform: Samsung B1320 5G modem + Broadcom BCM6776 Wi-Fi 8 SoC
- Target market: fixed wireless access gateways and broadband CPE
- Cellular standard: 3GPP Release 17
- Wi-Fi standard: emerging IEEE 802.11bn Wi-Fi 8
- Samsung B1320: 5nm modem, 3.43 Gbps downlink, 1.17 Gbps uplink
- Broadcom BCM6776: tri-band Wi-Fi 8, quad-core CPU, integrated multi-gig PHY
- Satellite support: NR-NTN and NB-NTN for n255 and n256 L- and S-bands
- Status: carrier trials and OEM sampling underway
“Broadcom is proud to lead the Wi-Fi 8 transition alongside Samsung and our valued ODM partners,” said Vijay Nagarajan, Vice President of Marketing, Wireless and Broadband Communications Division at Broadcom. “This partnership is a game-changer for the FWA market. The combination of Wi-Fi 8 and 5G prioritizes coordinated reliability, giving operators a tool that delivers a consistent experience to every corner of the home.”
🌐 Analysis: The platform positions FWA as a more integrated home broadband architecture rather than a simple cellular-to-Wi-Fi bridge. By pairing Release 17 5G, NTN support, and Wi-Fi 8 in a carrier-ready gateway design, Broadcom and Samsung are addressing operator requirements for lower CPE cost, lower power draw, and more predictable in-home performance as FWA scales beyond early deployments.
Profile: 3GPP Release 17
The foundational milestone concluding the first phase of the 5G NR standard.
| Category | Details |
|---|---|
| Standard | 3GPP Release 17 — a major evolution of the 5G specification that finalized the initial 5G trilogy (R15/16/17) and set the stage for 5G-Advanced (R18+). |
| Timeline | Protocol coding (ASN.1) frozen in June 2022 by the 3rd Generation Partnership Project (3GPP). |
| Main Focus | System expansion into new device types, spectrum expansion, network coverage enhancement, and native non-terrestrial network integrations. |
| Spectrum Expansion | Extended 5G New Radio (NR) support from 52.6 GHz up to 71 GHz (FR2-2 band), integrating the unlicensed 60 GHz spectrum. |
| NR-Light / RedCap | Introduced Reduced Capability (RedCap) to serve mid-tier IoT applications (e.g., wearables, industrial wireless sensors, surveillance) with optimized data rates, lower complexity, and extended battery life. |
| Satellite Connectivity | First formal support for Non-Terrestrial Networks (NTN), enabling direct-to-cell satellite connectivity for standard form-factor devices. |
| NB-NTN | Extends narrowband IoT (NB-IoT) and eMTC architectures to satellite payloads for global asset tracking, agriculture, and remote sensing. |
| NR-NTN | Adapts 5G New Radio protocols for Geosynchronous (GEO) and Low Earth Orbit (LEO) satellites to provide smartphone voice, basic broadband, and emergency messaging. |
| Network Enhancements | Introduced massive MIMO enhancements, optimized dynamic spectrum sharing (DSS), enhanced uplink coverage, and advanced power-saving features for both devices and network nodes. |
| FWA Relevance | Boosts Fixed Wireless Access viability through superior beamforming, multi-antenna improvements, millimeter-wave expansion, and support for high-power Customer Premises Equipment (CPE). |
| Industry Impact | Commercialized the transition of mobile networks from consumer smartphones into massive IoT, commercial aviation, maritime logistics, and true space-based telecom infrastructure. |
