At the Huawei Developer Conference 2026 (HDC 2026), Huawei dropped a headline that caught the wireless industry off guard: the full NearLink protocol stack will be open-sourced to the OpenHarmony community on July 15, 2026. For the first time, this short-range communication technology — previously locked inside Huawei’s own device ecosystem — will be freely available to any manufacturer, developer, or researcher who wants to build with it.

The move is being read as a strategic pivot. Rather than keeping NearLink (also known as SparkLink, or 星闪 in Chinese) as a proprietary moat, Huawei is betting that openness will accelerate adoption and push the standard toward genuine industry-wide use. The question the industry is asking: could this be the beginning of the end for Bluetooth?

What is NearLink, and why does it matter?

NearLink is a next-generation short-distance wireless communication standard developed under the International SparkLink Alliance (iSLA), an industry body founded in September 2020 under Huawei’s leadership. It was designed from the ground up to address the limitations of Bluetooth and Wi-Fi in a world where IoT devices are proliferating, real-time control is becoming mission-critical, and smart vehicles demand sub-millisecond latency.

The standard operates in two modes: SLE (SparkLink Low Energy), targeting low-power applications like wireless mice, earphones, and wearables; and SLB (SparkLink Basic), aimed at high-bandwidth scenarios such as wireless projection, vehicle infotainment, and industrial automation.

In May 2025, NearLink reached a significant international milestone when it was formally incorporated into an International Telecommunication Union (ITU) wireless access recommendation — a recognition that places it within the global standards framework, even if Western adoption remains limited.

NearLink vs Bluetooth: the numbers tell a striking story

On raw specifications, NearLink is not a modest incremental improvement — it is a generational leap. The standard achieves transmission speeds exceeding 12 Mbps versus Bluetooth’s ceiling of around 2 Mbps. Latency drops from Bluetooth’s typical 3–6 milliseconds to the microsecond range, roughly 30 times faster. Power consumption is claimed to be 60% lower, and the technology supports thousands of concurrent device connections, compared to Bluetooth’s practical limit of around seven.

Positioning precision is another standout: NearLink can locate devices to centimetre-level accuracy, versus the metre-level approximation that Bluetooth offers — a difference that matters enormously for automotive keyless entry, industrial robotics, and asset tracking.

Feature NearLink Bluetooth 5.x / BLE
Peak data rate ~12 Mbps ≤ 2 Mbps
Latency ~20 µs 3–6 ms
Power consumption ~60% lower Baseline
Concurrent connections Thousands ~7 devices
Positioning accuracy Centimetre-level Metre-level
Coverage range ~100 m ~50 m
Chip cost Higher (emerging) Low (mature)
Global device support China ecosystem only Billions of devices

The performance gap is real and significant. But hardware specifications rarely determine the winner of a platform war. Ecosystem does.

“NearLink can be read as the culmination of everything the industry has tried to do with Bluetooth over the years — now built from scratch, without the legacy constraints.”

Open source: a game-changer, or just the first move?

Open-sourcing the NearLink protocol stack is a significant strategic signal. Huawei’s terminal software president Gong Ti announced at HDC 2026 that the code — described as over 150,000 lines — will be made available on the OpenHarmony platform. The move hands manufacturers a complete blueprint: anyone can now build NearLink-compatible devices without proprietary black boxes or platform lock-in. For the Chinese IoT supply chain, this is potentially transformative.

But open source and patent-free are not synonymous. The International SparkLink Alliance operates under a FRAND (Fair, Reasonable and Non-Discriminatory) intellectual property policy. Under this framework, patent holders — primarily Huawei — must license standard-essential patents to any implementer, but “reasonable” does not necessarily mean free. A subset of patents may fall under FRAND-RF (Royalty Free) terms, but the exact scope remains subject to case-by-case negotiation. Developers within the Huawei/HarmonyOS ecosystem are unlikely to face near-term patent friction; those looking to implement NearLink in independent or international products would need to engage with the licensing framework directly.

Patent policy at a glance

The iSLA’s IP management rules require that any standard-essential patent be licensed under FRAND or more favourable terms. Some patents carry FRAND-RF (royalty-free) status. The open-sourced protocol stack code is free to use, but underlying standard-essential patents remain subject to separate licensing discussions with Huawei and other patent holders.

Where NearLink is already deployed

NearLink is not vaporware. Commercial deployment within China has been accelerating since the first NearLink-enabled device — the Huawei Mate 60 — shipped in August 2023. The technology has since expanded across a surprisingly diverse product range.

In consumer electronics, NearLink now appears in over 50 wireless HID devices including keyboards and mice, with gaming peripheral brand Rapoo shipping a NearLink-equipped gaming mouse in March 2026. The Huawei FreeClip 2 earphones received NearLink audio (E2.0) support via a firmware update in January 2026, delivering enhanced connection stability and interference resistance in crowded radio environments.

The automotive sector is perhaps the most telling indicator of where the technology is headed. NearLink car keys have been deployed across vehicles from over 70 manufacturers, including flagship models like the Zunjie S800. The technology enables decimetre-level positioning for keyless entry, resolving the “waiting outside” problem caused by imprecise Bluetooth-based locking systems. In industrial settings, a pilot at Huawei’s Songshan Lake factory demonstrated millisecond-level synchronised control across hundreds of devices simultaneously.

The case against a Bluetooth replacement — at least outside China

Bluetooth is not going to fade quietly. The standard underpins an estimated several billion active devices worldwide, maintained by the Bluetooth Special Interest Group (SIG) — a politically neutral, internationally governed body with members including Apple, Qualcomm, Intel, and Samsung. Its ecosystem depth is, by any measure, overwhelming.

The geopolitical dimension compounds the challenge. NearLink was founded in the aftermath of Huawei being forced to exit the Bluetooth SIG following US sanctions in 2019. That origin story is not lost on Western policymakers. The United States, European Union, and their technology allies have shown little appetite for adopting communication standards led by a Chinese company subject to export controls and national security scrutiny. Integrating a Huawei-led protocol into critical device infrastructure — whether consumer, automotive, or industrial — faces both regulatory and political headwinds that technical specifications cannot easily overcome.

For Western manufacturers, the calculus is straightforward: Bluetooth chips are cheap, the supply chain is mature, and the global developer ecosystem is extensive. The bar for switching is extraordinarily high, and NearLink’s open-source move, while meaningful within its own context, does not lower that bar for companies operating outside the HarmonyOS universe.

A realistic outlook: parallel standards, not a winner-takes-all race

The most accurate framing may not be “NearLink vs Bluetooth” at all, but rather a segmented future where both standards serve different markets and use cases. In China — and increasingly across the broader Chinese technology supply chain spanning Southeast Asia and parts of the Global South — NearLink is well-positioned to become the dominant short-range standard for high-performance applications: gaming peripherals, smart home systems, premium automotive, and industrial IoT where latency and reliability are non-negotiable.

Bluetooth will continue to dominate anywhere that ecosystem breadth, cross-platform compatibility, and chip cost are the deciding factors — which is to say, most of the consumer electronics market outside China for the foreseeable future.

The open-source release in July 2026 is best understood as a maturation signal rather than a disruption event. It confirms that NearLink is stable enough to expose publicly, lowers barriers to adoption within the HarmonyOS and OpenHarmony ecosystems, and begins — slowly — to build the kind of credibility that global standards require. Whether that credibility translates into international traction will depend on factors well beyond the code itself: patent terms, geopolitical climate, and whether the iSLA can genuinely attract non-Chinese members with real governance influence.

For now, the most honest answer to the question this article poses is: not yet, and not everywhere. But in the markets where Huawei has room to operate, NearLink has the technical foundation to define what short-range wireless looks like for the next decade.
