HaLow operates in the sub-1GHz band (900 MHz in the US, 868 MHz in Europe). Sub-1GHz RF behaves fundamentally differently from 2.4 or 5 GHz — it bends around obstacles, penetrates dense materials, and travels far on low power. Tagnetix designs and sources the RF system for distributed device networks that standard Wi-Fi can't reach.
| Feature | HaLow (802.11ah) | 2.4 / 5 GHz Wi-Fi |
|---|---|---|
| Frequency | Sub-1GHz (900 MHz) | 2.4 GHz / 5 GHz |
| Range | Up to 1 km per AP | 30–100 m typical |
| Penetration | Metal, concrete, walls | Blocked by dense materials |
| Power draw | Very low — battery viable | Higher — mains required |
| Devices per AP | Up to 8,191 | ~50–200 practical |
| Throughput | 150 kbps–86 Mbps | Up to 9.6 Gbps (Wi-Fi 6) |
Use this to qualify a deployment. Understand what you already have, what you need, and where ATRI Solutions adds value — individual parts, subsystems, or the complete solution.
Map what you have vs. what you need. ATRI can fill any gap — individual modules, subsystems, or the complete solution.
Strong in-house engineering — we supply modules. Need delivery — ATRI builds and deploys the entire system end-to-end.
Short timeline — sourced modules into existing hardware. Clean-slate deployment — full stack design and deployment.
A representative deployment pattern: a distributed retail signage network across several sites, each with a mix of price displays, secondary signage, and environmental sensors — all reporting back to a central cloud platform.
Sub-1GHz RF bends around and through the steel structures that kill standard Wi-Fi. One AP can cover an entire site from a single mounting point.
A roadside sign, multiple secondary displays, indoor signage, and environmental sensors — all on one HaLow AP. No separate networks, no separate infrastructure budget.
The gateway receives an update and fans it out to every node simultaneously — no manual changes, no inconsistencies across a site.
Nodes can run on small power supplies or battery. HaLow sleep modes keep every node alive between update cycles without draining power.
A small site and a large multi-device site use the same single-AP architecture. No redesign as a deployment grows.
The site edge controller caches the last known state. If internet connectivity drops, every node keeps operating correctly until the connection is restored.
