As the Short-Range Wireless Evolution Continues, What Role Does SparkLink/NearLink Have in the Future of Connectivity?

The wireless connectivity market continues to rapidly evolve. Wi-Fi’s development is accelerating through the transition to Wi-Fi 7 and Wi-Fi 8, while visions for Wi-Fi 9 are already starting to be set. Meanwhile, vendors continue to differentiate on power, throughput, latency, range, and other metrics to bring enhanced performance, while the incorporation of Wi-Fi sensing can open up new services thanks to the ability to detect presence and movement in the environment. In addition, Wi-Fi HaLow is starting to see real-world traction in the sub-Gigahertz (GHz) realm for extended range edge-enabled connectivity. On the Bluetooth® side, support for different topologies and continued enhancements such as Ultra Low-Latency (ULL) Human-Interface Device (HID), High Data Throughput (HDT), higher band operation, support for Internet Protocol version 6 (IPv6), and support for ambient Internet of Things (IoT) smart labels are further increasing opportunities for the technology. Alongside this comes Ultra-Wideband (UWB) and IEEE 802.15.4ab, combining secure ranging, radar and sensing, and high throughput low latency data transfer to enable a range of use cases in automotive, wearables, and asset trackers, among many others.

Initially developed by Huawei in the aftermath of U.S. sanctions and expulsions from standards bodies in 2019, SparkLink technology, also known as NearLink, seeks to unify multiple different wireless and wired standards under a single banner, shifting wired applications to wireless and targeting higher performance when compared to Wi-Fi, Bluetooth®, and UWB. There are several different elements to SparkLink technology, including:

• SparkLink Basic (SLB): This acts as a high-speed, high-performance, and more deterministic Wi-Fi alternative supporting ultra-low latency of 20 Microseconds (μs) and high-precision synchronization at sub-microsecond level, ideal for applications requiring low latency, high reliability, precise synchronization, high concurrency, and high security. Key applications include mobile devices, PCs, tablets, video, Extended Reality (XR), robotics, and mission-critical industrial connectivity.
• SparkLink Low Energy (SLE): This targets applications such as wireless audio, peripherals, wearables, digital keys, wireless battery management systems, home automation devices, healthcare devices, industrial sensors, and other devices that rely on low-power consumption. Additional enhancements including ultra-low latency of 125 μs, support for up to 12 Megabits per Second (Mbps( throughput via NearLink E1.0 and 16 Mbps via E2.0. SLE can also support sub-meter ranging for digital key and secure access applications. This acts as an alternative to Bluetooth® and UWB technology, and operates predominantly in the 2.4 GHz band.

Additional features for NearLink include Synchronous Link Positioning (SLP) technology. This uses UWB signals to achieve centimeter-level high-precision positioning for ranging while using SLE/SLB for discovery and connection management. Meanwhile, NearLink can also support sensing via SLE through adaptive frequency hopping and high-precision algorithms that can understand environmental changes and accurately determine target position and status. This could open up additional opportunities in smart home security and health monitoring-related applications. In September 2020, the SparkLink Alliance was officially established. In June 2023, the SparkLink Alliance was officially registered as the International SparkLink Wireless Short-range Communication Alliance (iSLA). The iSLA aims to promote the innovation and ecosystem development of new wireless short-range communication technologies to a global audience and has emphasized application scenarios such as connected vehicles, smart homes, intelligent devices, and smart manufacturing to date.

The NearLink 1.0 standard was officially released in November 2022 and encompassed the access layer, basic service layer, general content (architecture, identifier, etc.), security, and testing features. NearLink 2.0 was officially released in March 2025, and provided a more comprehensive communication foundation and richer application standards, fully supporting native audio and video, Human-Machine Interface (HMI)/HID, positioning (including SLP), and other NearLink applications such as digital key. NearLink 3.0 was initiated in June 2025 and is currently anticipated to be completed by 2027. Version 3.0 will continue to optimize communication performance, enhance access layer capabilities in positioning, sensing, and IoT, and achieve UWB and passive applications for all IoT scenarios.

From an ecosystem development perspective, iSLA was initially co-founded by 80 members, but has since grown to over 1,200 members, spanning industry institutions, universities, research institutes, chip and module vendors, automotive Original Equipment Manufacturers (OEMs( and component vendors, mobile and device vendors, smart home device manufacturers, manufacturing device vendors, and communications equipment providers, among others. iSLA is now actively attempting to promote the technology internationally. In May 2025, the International Telecommunication Union (ITU) incorporated the technology in its global wireless access standard. In August 2025, SparkLink Japan was established, while further events in Europe were hosted throughout 2025 and 2026.

On the vendor ecosystem, several chipset vendors have now developed NearLink solutions. Unsurprisingly, HiSilicon led the charge, with multiple NearLink Systems-on-Chip (SoCs), including the Kirin A2 and the Hi3863V100 and Hi387V100 (SLE + Wi-Fi 6 combos). Other vendors include Chengdu Aich Technology, Triductor, Beijing Sylincom, SIGCHIP, Bestechnic, and MacroGiga. However, NearLink chipset technology remains mostly restricted to Chinese vendors. In addition to offering enhancements to these technologies, most SparkLink SLE solutions are embedded alongside Wi-Fi or Bluetooth® technology, or a combination of both. For example, Triductor’s portfolio all support Bluetooth® Low Energy (LE), while additional variants such as the TR5330 support 2.4 GHz Wi-Fi, Bluetooth® LE, and NearLink SLE1.0.

From a device perspective, the market, to date, has been primarily driven by Huawei smart devices, including phones such as the Mate 60, Mate 70, Mate 80, Pura 70, Pura 80, Pura 90, Nova 15, Mate X6 and X7, tablets including the MatePad Pro and Pro Max, and various audio and peripheral accessories such as the Huawei FreeBuds Pro 3, FreeBuds Pro 5, and Freeclip 2. In addition, several NearLink mice and keyboards, gaming controllers, wireless routers, and cameras, have all arrived on the market. Meanwhile, several vehicles have also integrated NearLink support for automotive digital keys including the several models from AITO, Luxeed, Maextro, Stelato, and Shangjie. The majority of these rely on Huawei’s HarmonyOS, which in some cases uses NearLink for in-car entertainment and other car functions. To date, this has equated to over 100 million cumulative shipments. Almost all deployments, to date, have focused on SLE technology.

SparkLink’s ability to unify various wireless access technologies in an overarching standard is a compelling one from a technology perspective. It is also a ground-up approach that can leverage different techniques to reduce latency, increase throughput, and provide enhanced reliability, while combining data, ranging, positioning, and sensing, without supporting an existing legacy of devices, exhibiting clear advantages. However, SparkLink technology faces multiple challenges if it is to find success:

• Continued Technology Evolution: Other wireless technologies are not standing still and are actively addressing some of their weaknesses compared to NearLink. These could reduce the performance gap and de-incentivize investment in NearLink technology.  
• China (and Huawei)-Centric: There are currently no chipset vendors outside of mainland China that have developed NearLink solutions, and almost all high-volume devices on the market today come from Huawei directly. Given the origins of NearLink, there is a perception that the technology is controlled by Huawei and, by proxy, China. This has the potential to limit the opportunity not only outside of China but also domestically, as non-Huawei ecosystem players may not want to support the technology.
• Lack of Maturity: NearLink remains a relatively new standard, with chipset innovation driven primarily by HiSilicon and a few smaller Chinese players. The roadmap is also continuing to add new fundamental features, which may deter further solutions from emerging until these are completed. This is in stark contrast to the wider availability of Wi-Fi, Bluetooth®, and UWB Integrated Circuits (ICs) from numerous global players.
• SLB Deployments Are Lacking: Finally, almost all deployments of NearLink today are leveraging SLE technology. In contrast, SLB has yet to gain major traction. This could limit the broader utility of SparkLink and restrict its potential target market applications.
