What Is Wi-Fi HaLow? 802.11ah Range, Speed and Hardware

Wi-Fi HaLow keeps showing up in maker hardware this year, from USB adapters to ESP32 boards to OpenWrt gateways, and with good reason. It solves a problem every homelabber eventually hits: ordinary Wi-Fi does not reach the shed, the barn, the far end of a warehouse or the camera at the bottom of the garden. HaLow is the IEEE 802.11ah standard, and its trick is simple. It moves Wi-Fi down into sub-1 GHz spectrum, trading top-end speed for range and wall penetration, while keeping everything that makes Wi-Fi easy to use, including normal IP networking and modern security.

This guide explains how Wi-Fi HaLow works, what range and throughput to expect, how it compares with LoRa and regular Wi-Fi, and which hardware is worth a look today.

• Wi-Fi HaLow is IEEE 802.11ah, certified by the Wi-Fi Alliance since 2017, running in sub-1 GHz bands
• The Wi-Fi Alliance quotes roughly 1 km of range, strong wall penetration and coin-cell battery life measured in months to years
• Current Morse Micro MM8108 silicon reaches a 43.3 Mbps PHY rate on an 8 MHz channel with up to 26 dBm transmit power
• ABI Research figures cited by the Wi-Fi Alliance put 2026 HaLow chipset shipments at 24 million

What Is Wi-Fi HaLow and How Does It Work?

Conventional Wi-Fi lives at 2.4 GHz, 5 GHz and 6 GHz. Those bands carry a lot of data, but higher frequencies fade faster with distance and struggle with walls, trees and floors. Wi-Fi HaLow operates below 1 GHz. In the United States that typically means the 902 to 928 MHz band, and other regions use their own sub-GHz allocations; LILYGO, for example, sells separate 859 to 894 MHz and 902 to 928 MHz versions of its board, and Morse Micro's USB adapters operate within an 850 to 950 MHz range.

Lower frequencies travel further and pass through obstacles more easily, which is where HaLow's range comes from. The Wi-Fi Alliance lists four building blocks behind it: narrow-band OFDM channels, several device power-saving modes, native IP support and the latest Wi-Fi security. That last pair is the big differentiator. A HaLow device gets an IP address and speaks ordinary network protocols, and current hardware such as the Morse Micro USB adapters supports WPA3.

Channels are narrow by Wi-Fi standards. The MM8108 chip supports selectable widths of 1, 2, 4 and 8 MHz, with modulation and coding scheme levels from 0 to 10. Narrow channels at low modulation squeeze out the most range; wide channels at high modulation deliver the most speed.

How Far Can Wi-Fi HaLow Reach?

The Wi-Fi Alliance quotes approximately 1 km. Morse Micro specifies up to 1 km line-of-sight for its HaLowLink 2 gateway, Elecrow rates its ThinkNode G4 at beyond 1 km, and LILYGO quotes up to 1.2 km line-of-sight for its T-Halow P4 board. Notice the phrase line-of-sight. Real-world range depends heavily on the environment, antenna height and placement, regional transmit-power limits and channel width.

Practical tips for getting the most distance:

• Mount antennas as high as you reasonably can, and keep them clear of metal roofs and walls
• Use an external antenna on an SMA connector rather than a tiny onboard one when range matters
• Drop to a narrower channel width if you need distance more than throughput
• Check your regional regulations, since allowed frequencies and power vary by country

How Fast Is Wi-Fi HaLow?

Fast enough for most real IoT and monitoring jobs, but nowhere near modern home Wi-Fi. The current Morse Micro MM8108 tops out at a 43.3 Mbps PHY rate using an 8 MHz channel, which is what both the HaLowLink 2 and Morse Micro's USB adapters advertise. The Taixin module on the LILYGO T-Halow P4 is quoted at 150 Kbps up to 32.5 Mbps, and the ThinkNode G4 at roughly 32 Mbps.

Keep in mind that PHY rates are the raw over-the-air ceiling. Actual application throughput is lower once protocol overhead, distance and interference are counted. The OpenMANET project, which builds mesh networks on HaLow, reports 1 to 15 Mbps depending on the regulatory domain, which is a useful real-world reference for multi-hop setups. Even at the low end, that is comfortably enough for compressed security camera streams, telemetry from dozens of sensors, push-to-talk voice and remote SSH sessions.

Wi-Fi HaLow vs LoRa vs Regular Wi-Fi: Which Should You Use?

Each radio has a sweet spot, so here is how they compare in practice.

Wi-Fi HaLow (802.11ah)

• Range of roughly 1 km, with good penetration through walls and foliage
• Megabits per second of throughput, enough for video and full IP networking
• Native IP and WPA3, so standard apps and protocols just work
• Higher power draw than LoRa, though power-saving modes allow long battery life for sensors

LoRa and LoRaWAN

• Range of several kilometers or more on very little power
• Very low data rates, best for small sensor readings and short text messages
• Needs its own gateway and application conventions rather than plain IP
• Ideal for battery or solar sensors that report infrequently

Regular Wi-Fi (2.4, 5 and 6 GHz)

• Highest speeds by far, from hundreds of megabits to multiple gigabits
• Shortest range and weakest wall penetration of the three
• Universal device support, since every laptop and phone already has it
• Best inside a single home or office

The simple rule: if you need IP networking and some real bandwidth across a property or campus, choose HaLow. If you need years of battery life and only send a few bytes at a time, choose LoRa. We go deeper on the LoRa side in our Meshtastic, MeshCore and LoRaWAN explainer.

Best Wi-Fi HaLow Hardware to Buy

Morse Micro HaLowLink 2 Gateway

The HaLowLink 2 pairs a MediaTek MT7621 processor with the MM8108 HaLow radio through an AzureWave AW-HM677 module. According to LinuxGizmos, it also includes a MediaTek MT7603E for 2x2 802.11n Wi-Fi at 2.4 GHz, two Gigabit Ethernet ports, USB-C for power and Ethernet data, and an SMA antenna connector. It runs OpenWrt 23.05 with a web setup wizard and works as a router, access point or extender. Pair two units and one can carry a long HaLow link to the other, which then serves ordinary 2.4 GHz Wi-Fi or Ethernet to laptops, cameras and phones that have no HaLow radio of their own. It supports EasyMesh and IEEE 802.11s mesh, measures 88 x 68 x 24 mm and is sold through Seeed Studio, Mouser and DigiKey.

Elecrow ThinkNode G4

At $54, the ThinkNode G4 is the budget-friendly way to try HaLow. It is built on a MediaTek MT7628N running OpenWrt-based Linux 5.15 firmware, bridges Ethernet and 2.4 GHz Wi-Fi 4 devices over a HaLow link, and supports AP and STA modes plus 802.11s mesh, where each unit can act as a mesh gate or mesh point.

Morse Micro USB Adapters

If you already run an OpenWrt router or a Linux mini PC, a USB adapter is the most flexible route. Morse Micro's MM8108-based adapters sell for $58 on Mouser in USB-A and USB-C versions, each with an external SMA antenna, AP and station modes and WPA3. We covered them in detail in our look at Wi-Fi HaLow USB adapters.

LILYGO T-Halow P4

For makers who want a programmable node, LILYGO's T-Halow P4 combines an ESP32-P4 microcontroller, an ESP32-C6 wireless co-processor and a Taixin HaLow module on an M.2 2280-sized card. It starts at $26.57 and suits long-range camera and sensor gateways. See our full breakdown of the LILYGO T-Halow P4 ESP32-P4 board.

OpenMANET Firmware

OpenMANET is open-source firmware for building mobile ad-hoc mesh networks over HaLow. It is based on OpenWrt 24.10 and uses 802.11s with batman-adv routing under the GPL-3.0 license. It supports Raspberry Pi 4, CM4, 3B and Zero 2 W, along with HaLowLink 2, Heltec HT-HD01-V2 and Gateworks Venice boards, and carries push-to-talk voice, RTSP video and full IP networking.

What Can You Build With Wi-Fi HaLow?

Here are the projects where HaLow shines for homelab and maker users:

• Outbuilding internet: run a HaLow link from the house to a workshop, garage or barn, then serve normal Wi-Fi or Ethernet at the far end
• Remote security cameras: stream compressed video from a gate, driveway or field without trenching cable
• Farm and garden telemetry: collect soil, weather and water-level data from sensors spread across acres
• Event and field networks: set up a temporary mesh for a campsite, a race course or a community event
• Industrial monitoring: connect machines across a large warehouse or yard where 2.4 GHz coverage falls short

Is Wi-Fi HaLow Worth It in 2026?

For long-range IP networking, yes. The ecosystem has matured quickly. There are now affordable gateways, USB adapters, development boards and open-source mesh firmware, and the Wi-Fi Alliance's own figures point to tens of millions of HaLow chipsets shipping this year. The main caveats are regional frequency rules and the fact that your phone and laptop will not speak HaLow directly, which is why gateway and bridge setups are the most common way to deploy it.

Start small. Two gateways or a gateway plus one USB adapter is enough to test a link across your property before you invest in a larger mesh. For more long-range networking and single board computer projects, browse our mini computer coverage.

Frequently Asked Questions About Wi-Fi HaLow

Is Wi-Fi HaLow the same as regular Wi-Fi?

It is part of the Wi-Fi family and carries standard IP traffic with Wi-Fi security, but it uses different, sub-1 GHz frequencies. Ordinary phones and laptops cannot connect to it directly, so most setups use a gateway that bridges HaLow to normal Wi-Fi or Ethernet.

Does Wi-Fi HaLow need a license?

HaLow uses unlicensed sub-GHz spectrum, but the exact frequencies and transmit power you may use depend on your country. Buy the regional variant that matches where you live.

Can a Raspberry Pi use Wi-Fi HaLow?

Yes. OpenMANET firmware supports several Raspberry Pi models, and a USB HaLow adapter can add 802.11ah to a Linux system, subject to driver support for your setup.

How many devices can Wi-Fi HaLow connect?

HaLow was designed with large IoT deployments in mind, and its power-saving modes help many low-traffic sensors share a network. Real limits depend on the access point hardware and how much data each device sends.
