| 1. Verify regional frequency support | Sub-GHz operating bands, channel availability, transmit-power limits, and product approvals for each target market. | Permitted frequencies and radio rules vary by country. A device designed for one region may not be legal or usable in another. | Which exact frequency bands and channel widths does the product support? Is it approved for every country where it will be deployed? |
| 2. Check security implementation | Supported Wi-Fi security modes, encryption, device onboarding, credential storage, firmware signing, and update procedures. | Security depends on the complete implementation and configuration, not just the radio standard. Strong onboarding and update controls help protect large device fleets. | Which security modes are supported? How are devices provisioned, credentials protected, and security updates delivered? |
| 3. Evaluate real network capacity | Expected device count, reporting frequency, payload size, airtime use, gateway limits, and performance under simultaneous transmissions. | HaLow is designed for low-power, long-range connectivity and large IoT deployments, but practical capacity depends on traffic patterns, signal conditions, and access-point design. | Can the supplier demonstrate performance using our device count and traffic profile, including peak reporting periods? |
| 4. Validate coverage in the actual environment | Building materials, antenna placement, obstacles, interference, required data rate, and coverage at the edge of the site. | Sub-GHz signals can offer useful propagation characteristics, but achievable range varies with the environment, regulations, antennas, and link requirements. | Can we run a site survey or pilot? What coverage and link-quality measurements will be used for acceptance? |
| 5. Confirm integration options | Host interfaces, network management, APIs, IP support, gateway backhaul, and compatibility with existing cloud or local systems. | Integration affects deployment effort, monitoring, and ongoing operations. Confirm that the product fits the intended network architecture. | Which interfaces and management tools are available? Can the system connect to our existing applications and backhaul? |
| 6. Compare power and device requirements | Sleep and wake behavior, transmit duty cycle, battery type, expected battery life, antenna requirements, and operating temperature. | Battery life depends on how often devices communicate, signal conditions, hardware design, and application behavior; advertised figures may assume specific test conditions. | What test conditions support the battery-life estimate? Can we verify consumption using our reporting schedule and payloads? |
| 7. Review interoperability and lifecycle support | Standards conformance, certification status where applicable, firmware maintenance, security support period, documentation, and replacement availability. | Clear lifecycle support helps reduce integration risk and keeps a deployment maintainable as software, security needs, and regional requirements change. | What documentation, firmware updates, technical support, and product-lifecycle commitments are provided? |
