What are LoRa Certification Tests:Service Provider Companies

LoRa certification tests verify that LoRa and LoRaWAN devices comply with protocol specifications, interoperability requirements, radio regulations, and network performance standards. Certification service providers conduct RF testing, conformance validation, interoperability assessments, and compliance verification to ensure reliable operation across LoRa ecosystems. This guide provides list of LoRa Certification Test Providers located in Germany, USA, Japan, Spain, and Taiwan.

Typical LoRa Certification Testing

The LoRaWAN™ specification document V1.0.2 defines both mandatory and optional tests. The following test cases are commonly performed during LoRa certification testing:

• Functional tests of the application layer.
• Downlink PER (Packet Error Rate) test: The allowed limit is 5% PER.
• First and second receiver window tests, according to class-A/B/C definitions.
• Sequence number-related tests.
• Frequency channel (add/modify) tests.
• Uplink/Downlink tests based on confirmed or unconfirmed message types.
• Parameter change and check (downlink).
• Rate adaptation-related tests.
• Transmitter Power control-related tests.
• Retransmission tests for confirmed message types.

Optional Tests

In addition to the mandatory tests, the following optional tests may be conducted:

• Timing-related tests for downlink.
• MAC commands-related tests.
• Link check tests.
• Uplink frequencies tests.
