Network Access

Testing and Certification

Cellular network providers like AT&T, Verizon, T-Mobile, Telefonica, Telenor, Vodafone, … implement compliance programs to ensure that wireless products using their network adhere to industry standards and regulatory requirements. These programs involve testing and certification processes to guarantee that devices meet the specified criteria for performance, interoperability, and security. By enforcing compliance, network providers aim to maintain a high-quality and reliable wireless ecosystem for their users while ensuring that devices seamlessly integrate with their networks.

PTCRB is a certification program for wireless devices in North America. Established in 1997, the program ensures that devices comply with North American telecommunication standards. The purpose of the PTCRB is to provide the framework within which device certification can take place for members of the PTCRB. This includes, but is not limited to, determination of the test specifications and methods necessary to support the certification process for 5G NR and 4G LTE wireless devices.

PTCRB certification is available for testing and validating radio and protocol conformance. Devices that incorporate PTCRB-certified modules are called “Integrated Devices”. This is the process commonly used for IoT devices that are certified under a special IoT Network Certified program. Integrated Devices have the benefit of already having had most test cases completed when the module was certified. The only testing required is typically limited to interfaces such as the SIM, power, and antenna.
