TL;DR
Nordic Semiconductor has announced the nRF71 chip family, combining Wi-Fi 6, Bluetooth LE, Thread and edge AI in a system-on-chip aimed at battery-powered devices. The chips are sampling with selected customers; Nordic has also outlined plans for license-exempt Sub-GHz products, but has not shared model specifications or confirmed Thread Sub-GHz support.
Nordic Semiconductor has announced its nRF71 chip family, which combines Wi-Fi, Bluetooth Low Energy, Thread and edge AI in a single system-on-chip, and said it is developing license-exempt Sub-GHz solutions. The nRF71 is aimed at battery-powered smart-home and industrial devices; its arrival could give manufacturers another option for products that need Wi-Fi alongside low-power networking, while the Sub-GHz plans target longer-range connections.

Nordic identifies two versions: the nRF7120, with dual-band Wi-Fi 6, and the nRF7120E, with tri-band Wi-Fi 6E. Both have 4MB of non-volatile memory and 1MB of RAM. Unlike Nordic’s earlier nRF70 Wi-Fi companion chips, the nRF71 integrates connectivity and application processing, which may reduce the need for separate components in a device design.
The company says the new chips use up to 20 times less standby power than its current nRF70 series. That is a manufacturer comparison, not a measure of power use in every device or operating condition. Nordic also says the chips have two independent radios, allowing Wi-Fi and Thread or Bluetooth LE reception at the same time.
The nRF71 includes Nordic’s Axon neural processing unit for local machine-learning tasks. Nordic says supported models can run 10 to 17 times faster on the NPU than on the chip’s 256MHz Arm Cortex-M33 processor alone. Example applications include sound recognition, anomaly detection and image classification. The chips are sampling with selected customers, and Nordic is preparing a module based on them.
More Options for Connected Devices
Combining several wireless technologies with application processing could let manufacturers build devices that use Wi-Fi for network access while maintaining Thread or Bluetooth LE connections, without assembling the same functions from separate chips. The dual-radio design may be relevant to products that bridge networks or serve as Thread border routers, though Nordic has not supplied product-level performance or power figures for those uses.
The claimed standby-power reduction is pertinent to devices such as sensors and smart locks, where battery life can constrain the choice of connectivity. It does not establish that every Wi-Fi device built with the nRF71 will achieve a particular battery life. Actual results will depend on radio activity, software, network conditions and device design.
Nordic’s Sub-GHz plans address a different need: communicating over longer distances or through obstacles that can limit higher-frequency links. Smart meters, asset trackers and building-automation equipment are among the initial target uses described in the source report. Together, the announcements widen the choices available to developers balancing range, power, cost and protocol support.

Nordic’s Broader Wireless Push
Nordic is an established supplier of Bluetooth and Thread components, including chips used in Matter-over-Thread products. The new announcement extends that portfolio toward integrated Wi-Fi rather than replacing its existing wireless lines. It also reflects a wider industry move toward chip families that cover more than one major connectivity approach.
The source report points to Silicon Labs’ low-power Wi-Fi 6 platform and Espressif’s expansion from Wi-Fi into 802.15.4 products for Zigbee and Thread as examples of the same competitive shift. For device makers, a broader selection from suppliers can make it easier to match connectivity to a product’s requirements instead of relying on one vendor’s traditional specialty.
Sub-GHz is also attracting attention in the Thread ecosystem. The Thread Group approved work in September to extend Thread into Sub-GHz spectrum, with the aim of supporting longer-range IP mesh networking. That work remains under development; Nordic’s announcement does not establish that its planned products will implement the future standard.
“Up to 20 times lower standby power consumption compared with its current nRF70 series.”

Specifications Still to Come
Nordic has not announced specific Sub-GHz chip models or detailed hardware specifications, and the source report says an early-adopter program is open to developers. It is not clear when those products will be available or which open standards and proprietary protocols each will support.
It is also unconfirmed whether Nordic’s planned Sub-GHz devices will support Thread’s developing Sub-GHz extension. The nRF71’s published headline specifications do not establish how the chips will perform in finished products, how much power they will use under particular workloads, or what they will cost. Nordic has said the family is sampling with selected customers, but has not provided a general availability date in the supplied material.
Sampling and Sub-GHz Development
The immediate next step for the nRF71 family is evaluation by its selected sampling customers as Nordic develops a module based on the chips. No public launch or retail availability date is included in the supplied report, so device makers will need further information about production timing, pricing and detailed performance before making final product plans.
For Sub-GHz, developers can join the early-adopter program, according to the report. Further announcements will be needed to clarify chip models, radio specifications, standards support and release schedules. Thread Sub-GHz work is also continuing separately, leaving the relationship between that developing standard and Nordic’s planned products unresolved.
Key Questions
What are the Nordic nRF71 chips?
The nRF71 family is a system-on-chip line combining Wi-Fi, Bluetooth LE, Thread and edge AI. Nordic has announced the dual-band Wi-Fi 6 nRF7120 and tri-band Wi-Fi 6E nRF7120E.
Are the nRF71 chips available now?
The chips are sampling with selected customers, and Nordic is preparing a module based on them. The supplied report does not give a general availability date.
What does Nordic claim about power and AI performance?
Nordic says the chips have up to 20 times lower standby power than its current nRF70 series. It also says supported machine-learning models run 10 to 17 times faster on the Axon NPU than on the 256MHz Arm Cortex-M33 processor alone. These are company claims; the report does not give test conditions or device-level results.
Will Nordic’s Sub-GHz chips support Thread?
That has not been confirmed. Thread’s Sub-GHz extension is under development, and Nordic has not said whether its planned Sub-GHz products will support it.
