1 Kilometer of Wall-Penetrating Range, Years of Battery Life: Why Wi-Fi HaLow Is the New Answer for Industrial IoT Networking

An Old Problem: Why IoT Connectivity Always Seems to Demand a Trade-off

Anyone who has selected a wireless connectivity technology for an IoT project has run into this dilemma:

• Traditional Wi-Fiis fast and gets you straight onto the internet, but the 2.4GHz/5GHz bands have limited range — outdoor coverage typically starts degrading noticeably after just a few dozen meters, and the power draw is hard on battery-powered devices that need to stay online long-term.

• LPWAN technologies like LoRa and NB-IoTsolve the range and battery-life problem, but data rates usually top out somewhere between a few hundred bps and a few dozen kbps — not even enough to comfortably send a handful of image frames. Most of these protocols also aren't natively IP-based, which means you need an extra gateway layer just to translate the protocol before your data reaches the cloud.

• Bluetooth and Zigbeeare low-power and flexible to deploy, but transmission range is typically measured in tens of meters, so covering a large factory campus or industrial park means stacking up a lot of repeater nodes.

Long range, high throughput, low power, and easy connectivity — historically, it's been hard to get all four in a single wireless technology. That's exactly the gap Wi-Fi HaLow was designed to fill.

What Is Wi-Fi HaLow

Wi-Fi HaLow is the Wi-Fi Alliance's commercial name for theIEEE 802.11ahstandard, finalized by the IEEE in 2016 and formally released in 2017. It operates in theSub-1GHzband — internationally, this usually means frequencies around 900MHz (902–928MHz in the US, roughly 863–868MHz in Europe), while domestic Chinese chipset designs are typically built around the 750–950MHz range. This is a different band entirely from the 2.4GHz/5GHz/6GHz Wi-Fi we use every day, and operating at a lower frequency gives it several characteristics traditional Wi-Fi simply doesn't have:

① Longer range.Lower-frequency radio waves diffract more and lose less energy over distance, so for the same transmit power, the signal travels farther. Industry sources indicate Wi-Fi HaLow can cover over 1 kilometer under line-of-sight conditions; with higher transmit power, some vendors have even demonstrated video transmission at ranges beyond a kilometer (typically for mobile applications like drones and unmanned surface vessels).

② Stronger wall penetration.Lower-frequency signals lose less energy passing through walls, metal structures, and other obstacles — a real solution for factory floors, basements, and multi-story buildings where traditional Wi-Fi signals simply can't punch through.

③ Lower power consumption.Wi-Fi HaLow introduces scheduling mechanisms likeTWT (Target Wake Time)andRAW (Restricted Access Window)— in short, the access point and each device agree in advance on exactly when the device should wake up to send or receive data, letting it sleep deeply the rest of the time instead of continuously burning power monitoring the channel. This is what makes months — or even years — of battery life achievable for battery-powered sensors.

④ Larger network scale.Wi-Fi HaLow uses a star topology, and a single access point can theoretically support up to8,191 connected devices— far beyond the few dozen devices a typical Wi-Fi AP can reliably support, making it well suited to large-scale sensor deployments.

⑤ Native IP, no extra gateway required.This is the most fundamental difference between Wi-Fi HaLow and LPWAN technologies like LoRa or NB-IoT — it carries forward the standard Wi-Fi protocol stack, so devices can connect directly to an IP network without deploying an extra protocol-translation gateway layer, which meaningfully lowers cloud integration and operational complexity.

Of course, every technology involves trade-offs. To achieve long range, low power, and large-scale networking, Wi-Fi HaLow narrows its channel width down to 1/2/4/8/16MHz (much narrower than the 20/40/80MHz common in traditional Wi-Fi), and the cost is lower peak throughput — most commercial chipsets deliver physical-layer throughput somewhere between a few hundred kbps and a few dozen Mbps, well short of the hundreds of Mbps typical of Wi-Fi 5/6. But for the vast majority of IoT data-collection use cases — sensor readings, status reports, low-frame-rate imagery — that throughput is more than sufficient. The "extra bandwidth" you're not using is exactly what you're trading for range and power efficiency.

Where Wi-Fi HaLow Sits Among IoT Connectivity Technologies

Wi-Fi HaLow occupies a spot that was previously largely empty:faster than LoRa/NB-IoT, longer range than traditional Wi-Fi/Bluetooth, while retaining the native-IP, direct-to-cloud convenience of the broader Wi-Fi ecosystem.That's why it's often described as filling the gap between short-range, high-speed Wi-Fi and long-range, low-speed LPWAN.

Where the Technology Actually Gets Deployed

Based on current industry practice, the most mature application areas for Wi-Fi HaLow today include:

• Long-range industrial sensor networks— data backhaul from large numbers of distributed sensors (temperature/humidity, pressure, vibration, energy consumption, etc.) across factories, chemical parks, and mining sites, with a single AP covering what previously required multiple tiers of repeaters;

• Long-range wireless security monitoring— integrating HaLow into NVRs (as the access point) and IP cameras (as endpoints) enables a "one-to-many" wireless HD monitoring network with coverage and penetration well beyond traditional Wi-Fi, particularly suited to perimeter security and outdoor campuses where cabling costs are high;

• Remote control and tracking of distributed equipment— in sectors like renewable energy, solar, and agriculture, where individual units are spread over a wide area but need to be centrally coordinated (for example, independent actuator units across a large array), running cable to every node scales cost and installation difficulty linearly or even exponentially with array size. HaLow's cable-free, long-range characteristics significantly lower the deployment barrier for this kind of scenario;

• Smart agriculture— large fields, greenhouses, and farms are too spread out for traditional Wi-Fi or Bluetooth to cover; Wi-Fi HaLow can cover an entire area with far fewer access points for soil, weather, and equipment-status monitoring.

Industry Status: A Good Technology, Still Constrained by a Scarce Chip Supply Chain

Wi-Fi HaLow has been a finalized standard for nearly a decade, but commercial chipsets have only really matured and reached volume production in the last two to three years — which is the core reason adoption still lags behind how good the technology is on paper:very few companies actually make HaLow chips.The most active players globally today are Australia's Morse Micro, South Korea/US-based Newracom, and China's Zhuhai TaiXin Semiconductor. Even combined, these three remain essentially the entire field in this space — which means that once a given solution commits to a chip partner, it has effectively locked in access to one of the scarcest, most valuable supply-chain resources in this still-narrow segment.

Alinket's Position in This Space: A Complete "ALRconnected" Long-Range Wi-Fi Solution

At Alinket, the Wi-Fi HaLow direction isn't a single standalone module — it's already a completeALRconnected long-range Wi-Fi solution, built from three products working together, with the core chip solution built onMorse Micro— one of the most technologically mature and ecosystem-ready Wi-Fi HaLow chip vendors in the world today.

ALX890B — The Long-Range Wi-Fi Controller on the Device Side

A compact, low-power, long-range network controller supporting the IEEE 802.11ah standard, designed to be embedded directly into instrumentation, AI-enabled devices, industrial equipment, and other endpoint hardware. Core specifications:

• Communication range of up to 1 kilometer(500–1,000 meters in open outdoor environments), operating in Wi-Fi Station mode with a built-in TCP/IP stack and support for multiple protocol interfaces for strong compatibility;

• Measured throughput of approximately 40Mbps at an 8MHz channel width, closely matching the Morse Micro chipset's theoretical peak of roughly 43.33Mbps at the same channel width — meaning there's no significant gap between lab-spec numbers and real-world performance, and the solution's actual delivered capability lines up with what's on the datasheet;

• Operating temperature range of -30°C to +85°C, covering the vast majority of outdoor and industrial-site extreme-environment requirements;

• Compact 34.8 × 14.3 × 2.2mm form factor, with a full complement of UART/I2C/SPI interfaces, making it easy to embed into space-constrained end devices;

• RoHS/CE/FCC certified;

• Modulation covering OFDM/BPSK/QPSK/16-QAM/64-QAM, with channel bandwidths of 1/2/4/8MHz, consistent with the narrowband transmission design of the 802.11ah standard.

DGW890 — The Dual-Band Data Gateway That "Translates" HaLow Into Standard Networking

If ALX890B solves how an endpoint gets its data out, DGW890 solves how that long-range data gets onto a standard network. It integratesboth Wi-Fi HaLow and Wi-Fi 4in a single dual-band unit, supporting AP/STA/Bridge modes, and can aggregate data from large numbers of ALX890B endpoints at scale before uploading it to local or remote servers over a standard Wi-Fi connection:

• Supports up to 8,000 stable connections per unit— a networking scale that goes well beyond typical home or commercial routers in this segment;

• Also achieves a communication range of500–1,000 metersin open environments, with strong wall and obstacle penetration;

• Rich interface set (RJ45, RS232 industrial interface, USB Type-A), DC12V powered, with an operating temperature range of-30°C to +80°C;

• AlsoFCC and CE certified.

ALX-N25 — A Dedicated Router That Simplifies Deployment

Used to enable wireless switching and access between the Wi-Fi AP and endpoint devices, and can connect directly to a POE switch, further simplifying on-site deployment of the overall long-range solution.

Taken together, these three products address a very concrete real-world problem:when sensors, instruments, and endpoint devices are spread across an area larger than a single Wi-Fi AP can cover, and you don't want to run new cabling or accept the added complexity of LoRa/NB-IoT-style protocol-translation gateways, what's the most practical way to solve it?ALX890B gives endpoints the ability to "see far and run long on battery," DGW890 aggregates those long-range connections into a standard network at scale, and N25 makes on-site deployment easier. Together, they form a deployable, complete long-range Wi-Fi networking solution — not just a chip module that leaves customers to build the rest of the system themselves.

Regulatory Status: Already Certified for Two of the World's Largest Markets

Because Wi-Fi HaLow operates in the sub-1GHz band, exact frequency allocations and power limits vary by region — there's no single global channel plan, so this is genuinely worth checking before deployment. The good news is that ALX890B and DGW890 have already cleared certification for the two largest overseas markets:

• United States— certified underFCC Part 15.247, which governs the 902–928MHz ISM band (maximum peak conducted output power of 1W/30dBm);

• European Union— certified underETSI EN 300 220-2, which governs the 863–868MHz SRD band.

That means for US and EU deployments, the regulatory groundwork is already done — you're not waiting on a certification cycle to get a pilot running. Other major markets, including Japan, South Korea, and Australia, have also approved Wi-Fi HaLow operation, but with their own specific frequency allocations and power limits that differ from the US/EU bands. If your deployment targets one of these markets — or any market outside the US/EU — Alinket's engineering team can help confirm the applicable frequency plan and any additional local certification requirements for your specific project, so you're not left to work through unfamiliar regulatory requirements on your own.
