TL;DR
Nordic Semiconductor has announced the nRF71 system-on-chip family, combining Wi-Fi, Bluetooth LE, Thread and on-device AI, and says the chips are sampling with selected customers. The company also plans license-exempt Sub-GHz solutions, but has not disclosed models or confirmed support for Thread’s developing Sub-GHz standard.
Nordic Semiconductor has announced its nRF71 chip family, combining Wi-Fi 6, Bluetooth Low Energy, Thread and edge-AI processing in a system-on-chip, while separately outlining plans to enter the license-exempt Sub-GHz market. The announcements broaden Nordic’s wireless offerings for smart-home and industrial devices, although the company has not yet released detailed specifications or model names for its Sub-GHz products.

The nRF71 family is intended for battery-powered smart-home and industrial products. Nordic lists two variants: the nRF7120, with dual-band Wi-Fi 6, and the nRF7120E, with tri-band Wi-Fi 6E. Both are specified with 4MB of non-volatile memory and 1MB of RAM. Unlike Nordic’s earlier nRF70 Wi-Fi companion chips, the new products combine wireless connectivity with application processing, which could reduce the number of separate components a device needs.
Nordic says the chips use up to 20 times less standby power than its current nRF70 series. That is a company comparison, not an independently verified measurement in the supplied material. The chips also have two independent radios, which Nordic says can allow Wi-Fi and Thread or Bluetooth LE reception at the same time. Such concurrent operation could suit devices that need links across different networks, including bridges and Thread border routers.
The family also includes Nordic’s Axon neural processing unit for local machine-learning tasks such as sound recognition, anomaly detection and image classification. The company says supported models can run 10 to 17 times faster on the hardware than on its 256MHz Arm Cortex-M33 processor alone. The chips are sampling with selected customers, and Nordic is preparing a module based on them; no commercial availability date or pricing is provided.
More Protocols in One Device
Putting Wi-Fi, Thread, Bluetooth LE and application processing on one chip could give manufacturers more flexibility when designing connected products. A device maker may be able to select or combine wireless links according to power use, range and network role, rather than relying on a separate Wi-Fi companion chip. Whether that reduces a finished product’s cost or power draw will depend on implementation and has not been established by the announcement.
The claimed standby-power improvement could matter for sensors and locks that need Wi-Fi without frequent battery replacement. Dual-radio operation could also help products maintain connections across different network types. These are potential uses, not confirmed product outcomes: the source provides no independent test results, battery-life figures or specific device launches using nRF71.
The planned Sub-GHz line targets another set of needs: longer range and better signal penetration through obstacles for uses such as meters, asset tracking and building automation. For industrial operators and smart-home manufacturers managing large sites, it could add a connectivity option where 2.4GHz links are difficult to use. The eventual reach, performance and standards support remain unknown.

Nordic’s Wireless Expansion
Nordic is already a supplier of Bluetooth and Thread components used in connected devices, including Matter-over-Thread products. The nRF71 announcement extends that portfolio into integrated Wi-Fi rather than positioning Wi-Fi only as a companion function. The source describes this as part of a wider industry movement: chip companies are adding support for wireless technologies beyond their traditional specialities.
Silicon Labs has introduced a low-power Wi-Fi 6 platform alongside its Zigbee and Thread offerings, while Espressif, known for Wi-Fi modules, has expanded into 802.15.4 products for Zigbee and Thread. The competition gives manufacturers more choice, but the announcements alone do not establish which platform will be cheaper, more efficient or more widely adopted.
Sub-GHz is also drawing attention in the Matter and Thread ecosystem. The Thread Group approved work in September to extend Thread into Sub-GHz spectrum, aiming to address longer-range commercial and industrial uses. That work is still under development. Nordic has not confirmed that its planned Sub-GHz products will support the proposed Thread extension.
“Up to 20 times lower standby power consumption compared with its current nRF70 series.”

Sub-GHz Specifications Still Pending
Nordic has not announced Sub-GHz chip models, detailed hardware specifications, pricing or release dates. It has also not confirmed whether those products will support Thread’s developing Sub-GHz standard. The relationship between the company’s planned platform and any future Matter or Thread deployments therefore remains unsettled.
For nRF71, the source gives headline memory and connectivity details, but not chip dimensions, full power profiles, throughput, certification status, production timing or the conditions used to calculate the quoted performance comparisons. The company’s statements about power savings and machine-learning speed should be understood as claims from Nordic, not independent evaluations. Specific customer products and launch plans have not been identified.
Customer Sampling and Early Access
Nordic says the nRF71 family is sampling with selected customers and that it is preparing a module based on the chips. Those steps may give developers an opportunity to evaluate the integrated radios and AI hardware, but the company has not supplied a public commercial launch schedule in the source material.
An early-adopter program is open for developers interested in Nordic’s Sub-GHz plans. The next concrete details to watch for are named products, hardware specifications, supported protocols and availability dates. Until Nordic confirms compatibility with Thread’s Sub-GHz work, manufacturers should not assume the announced Sub-GHz platform will connect to that standard.
Key Questions
What are the Nordic nRF71 chips?
The nRF71 family combines Wi-Fi, Bluetooth Low Energy, Thread and application processing on a system-on-chip, with an Axon neural processing unit for supported on-device machine-learning tasks.
Which Wi-Fi versions do the announced models support?
