Tests are derived from LoRaWAN ™ specification and are covered currently for Class A
(Class C will most probably be available in late 2016).
The following tests are covered today:
- Activation OTA / by personalization
- Application functionality test
- Downlink Packet Error Rate tests (allowed 5% PER)
- Cryptography tests
- Receive Window test (1st and 2nd)
- Handling of sequence number
- Device Status Request test
- Add/Modify channel tests
- Confirmed/Unconfirmed uplink/downlink test
- Modify and verify of setting downlink parameters
- Modify and verify downlink timing parameters
- Data rate adaptation tests (incl. Optional DRs)
- Transmit Power control tests
- Confirmed / unconfirmed frames tests
- Retransmission of confirmed frames
Additional (optional) tests could be:
- Disable non-default uplink channels
- Downlink RF Timing Test
- Downlink Frame Pending feature
- Link Check Request test
- Simple tests for MAC commands
- Check uplink frequencies
The report that IMST provides as the output from LoRaWAN Radiation Performance measurement gives antenna diagrams showing the minimum and maximum values for the TRP (Total Radiated Power) and TIS (Total Isotropic Sensitivity). Based on these figures, a network operator can grade devices and ensure a good and smooth network availability and performance. Within development these measurements would help manufacturer to improve their designs.
The certification process in general is as follows:
LoRa® Certification OverviewThe LoRaWAN™ Certification Program provides assurance to end customers that their application-specific end devices will operate on any LoRaWAN network. The scope of the Certification Program confirms that the end device meets the functional requirements of the LoRaWAN protocol specification. The program includes a suite of tests that are specified in the LoRa Alliance End Device Certification Requirements document*.
Device manufacturers must be a member the LoRa Alliance to be LoRa Certified and must use one of the accredited LoRa Certification test houses to do the functional protocol testing. Upon completion of the tests, the results will be listed on the LoRa Alliance website, and upon compliance a LoRa Certification certificate will be issued by the LoRa Alliance.
LoRaWAN™ Certification Process
- Contact a LoRa Alliance authorized test service provider for a quote.
- Complete the certification questionnaire* available on the LoRa Alliance website or from the test service provider.
- Prepare your product(s) for certification.
- Must fulfill LoRaWAN Specification V1.0.2 which is available from LoRa Alliance. Older versions are also still covered.
- Must fulfill LoRa Alliance End Device Certification Requirements* for EU. Specification is available from LoRa Alliance.
