Start with the approved complete manufacturer MPN and distinguish a bare radio IC from a module or development kit. LoRa modulation capability is not a complete LoRaWAN implementation. Frequency coverage is a device capability, not permission to transmit in every target region.

Procurement verification checklist
- Full MPN, package, carrier and manufacturer document revision.
- Approved band and protocol-stack configuration, host commands and reference clock.
- Matched frequency, modem, bandwidth, spreading factor, error criterion, voltage and temperature for comparisons.
- Source and offered-lot evidence, required quantity and delivery conditions.
- Customer approval of hardware, firmware, RF matching and regulatory changes.
