What is Wi-Fi HaLow?
Wi-Fi HaLow is Wi-Fi based on the IEEE 802.11ah standard. It uses radio frequencies below 1 GHz to connect devices over longer distances and support low-power IoT applications. It can carry IP traffic for sensors, cameras and network connections, with performance determined by the hardware, radio settings and installation.
The useful question is not simply how far it reaches. Start with the data your application needs to send, how often it sends it, and the conditions between the devices.
How does it differ from conventional Wi-Fi?
Conventional Wi-Fi commonly uses 2.4, 5 or 6 GHz. HaLow uses sub-GHz channels and requires HaLow-capable radios at both ends of its wireless link. It complements the Wi-Fi already used by phones and laptops rather than making those devices directly compatible with a new frequency band.
For example, a pair of HaLowLink 2 devices can carry the connection over HaLow and provide a 2.4 GHz hotspot at the remote end. A phone connects to that local hotspot; it does not need a built-in HaLow radio.
How far and how fast can it connect?
Distance and throughput must be considered together. Buildings, terrain, antenna placement, interference and the selected channel affect the useful connection. A strong link can support a faster radio rate; a difficult link may need a more robust, slower setting.
Morse Micro's MM6108 datasheet lists a maximum PHY rate of 32.5 Mbps at 8 MHz. The MM8108 datasheet lists 43.3 Mbps at 8 MHz using 256-QAM. PHY rates describe the radio link, not guaranteed application throughput. Available channel widths also depend on the deployment region.
Use measured trials to understand the conditions behind a result. The Joshua Tree field trial demonstrates long-distance operation in an open, quiet environment; it does not predict performance through your building.
What applications suit Wi-Fi HaLow?
- Cameras and access control: evaluate the required video bitrate, upload traffic and number of active devices.
- Agriculture and industrial monitoring: assess coverage at the actual sensor locations and plan power and maintenance.
- Network extension: connect a remote location and provide Ethernet or conventional Wi-Fi access there.
Battery life is application-specific. Target Wake Time can schedule when compatible stations wake to exchange traffic, reducing time spent awake. Battery capacity, reporting frequency and the rest of the device still matter.
How does HaLow compare with LoRaWAN?
They serve different traffic needs and can work together. Explore modelled data rate and distance with the Wi-Fi HaLow vs LoRaWAN calculator, then read the comparison beneath it. For a complementary use case, see the LoRaWAN gateway backhaul demonstration.
Where should I start?
To evaluate a network, explore development resources and choose hardware for your region. To integrate HaLow into a product, compare Morse Micro chips and available modules, then use their datasheets and design guides. Test your expected traffic on the intended site before choosing the final installation.
