PTCRB certification FAQs

For PTCRB related questions and answers take a look here!

What is PTCRB?

PTCRB provides a certification framework for GERAN (GSM), UTRAN (UMTS) and E-UTRAN (LTE) mobile devices and modules for usage on PTCRB operator networks.

It was established in 1997 by North American cellular network operators.

PTCRB certification ensures compliance with a set of cellular network standards. Without PTCRB certification, manufacturers run the risk that their devices are being blocked from North American networks.

For whom are the PTCRB certification rules mandatory?

Module manufacturers as well as end-product manufacturers, who implement PTCRB-certified modules, are obliged to follow the PTCRB certification processes.

PTCRB certification is applicable for devices operating in the 850, 1900 MHz bands for GSM, the FDD Bands II, IV, V for UMTS and all PTCRB relevant eFDD bands for LTE.

What happens if I use a pre-certified module?

For North American markets, manufacturers who integrate a pre-certified module into their GSM/UMTS wireless M2M device, must submit their “end-product” in its final (production) form factor to a PTCRB-authorized test laboratory for testing & certification. Only a minimal amount of testing is requested in these cases, because the majority of the test cases have already been completed when the module was initially certified. These tests are carried out to ensure that the interfaces associated with the integration will meet performance requirements expected by the PTCRB.

Can I avoid problems during certification?

Pre-certification testing at 7layers enables you to avoid running into unforeseen difficulties during the official PTCRB Certification Processes. Pre-certification testing covers some Radiated Spurious Emissions (RSE) tests and some CTIA OTA tests. While such tests cannot detect every potential problem, they can give a higher degree of confidence before starting the official PTCRB Certification process. They can therefore prevent costly re-tests should failures be encountered during the official certification process.

Which is the best way to start?
