In response to the evolving mobile Customer Equipment technology around the world, KMO Labs provides fast and cost-effective mobile network access certification. We are a leading supplier of mobile terminal network technology certification. Our facilities are fully certified and based on market priority for laboratory improvements to meet the changing needs of customers. For example: In response to customer testing requirements for millimeter wave mmWave products, KMO Labs has extended the upper limit of RF testing capabilities to an astonishing 325GHz.

KMO Mobile Terminal Laboratory is the first Australian mobile terminal product accreditation laboratory in China. The S042 test report issued by KMO has been recognized by Australian authorities, regulatory agencies and the government.

Our KMO is also an accredited testing laboratory for 5GNR, LTE, CDMA, UMTS (WCDMA) and GSM certification schemes, and can test all 5G, 4G, 3G and 2G wireless products, including smart phones, feature phones, modules, IoT (M2M) devices, Wireless routers, hotspots, tablets, laptops, infrastructure equipment, etc.

Our KMO queue appointment time is only 3 days at the fastest, and our KMO provides instant online order value-added services. By bundling mobile terminals with other testing and certification requirements (telecom access, mobile access, radio frequency, electromagnetic compatibility, safety, environment, energy efficiency, performance, etc.), time and money can be saved. With KMO, you will eliminate the hassle of using multiple laboratories, logistics delays and transportation costs.

Our KMO mobile terminal testing & certification services include:

5G: NR (New Radio)
GCF Global Certification Forum (GCF),
PTCRB (PCS Type Certification Review Board),
CTIA (the Cellular Telephone Industries Association) and CCF (CDMA Certification Forum)


GCF stands for the Global Certification Forum, which certifies mobile devices working on cellular networks. GCF is a partnership between mobile network operators, infrastructure providers, equipment suppliers and testing organizations that establishes a certification process to ensure that mobile devices comply with 3GPP standards, the group that defines the standards. GCF certification ensures that mobile devices will operate on different cellular networks that adopt the 3GPP standard.

GCF's motto is "Once tested, used anywhere", highlighting the widespread acceptance of GCF-approved equipment.

GCF certification is required for all kinds of devices running on cellular networks, including phones, laptops, and tablets. Smart phone, USB dongle, mobile hotspot device, M2M device, etc. GCF certification includes conformance, interoperability, and field testing.

Products launched in Europe, Asia and other parts of the world usually require GCF certification. In North America, PTCRB certification is required. The test cases for GCF and PTCRB certification are very similar in that they both test for compliance with the 3GPP standard.

A list of GCF-approved devices is listed on the GCF website. For each GCF-approved device, the following information is listed:

* Name of manufacturer

* Product name

* Device functions

* Supported technologies -- GPRS, EDGE, UMTS, etc

* Supported frequency band

* Date of GCF certification

GCF Certification Process for Connected Devices GCF has established optimized methods to obtain certification of qualified devices, thus significantly reducing cost and time. The three requirements for using this optimization process are:

* Embedded modules used in connected devices must be GCF certified

Embedded modules must be certified less than 3 years prior to certification of the connected device

* 3GPP communication cannot be the primary function of the connected device.

The equipment manufacturer is responsible for selecting the test cases that will be used to validate the equipment. The manufacturer must determine whether the functionality or performance of the module is changed by integration in the device. Manufacturers shall select field test requirements (Annex F.5) and interoperability tests (Annex G) from GCF certification standards.

After the connected device has passed the applicable tests, the manufacturer shall submit a "Certification Statement" through the GCF website, which includes the following information:

A terminal that

Terminal declaration for GCF authentication

Field test result

Over the air (OTA) antenna performance measurement

List of applicability of certification standards
