Over-the-air (OTA) testing proves the performance and reliability of wireless devices and their antennas and other components.
Measurements like Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS) performed in the product’s application field validate its compliance with specified standards.
OTA testing gives wireless device manufacturers and distributors the assurance that their products not only meet performance and regulatory requirements but also are ready to be sold on the market.
CETECOM has the competency, capabilities, and capacity
to support the most demanding product launches in a connected world.
For GSM, UMTS, LTE, and now 5G, CETECOM has been at the forefront of wireless testing solutions. We are your reliable and trusted partner throughout a product’s lifecycle, validating its quality and performance and helping to speed your time to market. Our OTA testing team of industry veterans runs a double-shift operation to deliver fast turnaround times and laser-accurate results for the Device Under Test (DUT).
We have state-of-the-art OTA testing facilities in the Silicon Valley (California, USA) and Germany. Our Silicon Valley site hosts seven OTA anechoic chambers to test products including radio technology, each with multiple testing capabilities. This capacity and flexibility enable us to serve you sooner and shorten your testing times.
Additionally, our chambers support OTA testing using head, hand, and forearm phantoms to closely represent the way wireless devices are actually used. This type of testing provides a practical analysis of the Over-the-Air (OTA) performance and requirements from a product design perspective.
CETECOM is CTIA-authorized and an expert in the latest test plans from the largest U.S. network operators. Our engineers also support R&D consulting services such as customer-tailored pretesting and troubleshooting.
We are a preferred lab for the top U.S. carriers and, in some cases, the exclusive lab for OTA testing. We know each carrier’s requirements and can certify multiple carriers at the same time, accelerating your speed to market.
Building IoT-capable devices can be tricky. CETECOM can connect you with some of the industry’s best design houses, module makers, antenna manufacturers, and other companies skilled in successful product launches.
Industrial and commercial routers and access points are becoming increasingly complex. Multiple technologies (Bluetooth, Wi-Fi, LTE/4G, 5G) on a single device can be challenging. Our extensive experience with these types of devices and the professional power of our dedicated experts provides assurance that your device will be tested efficiently and reliably.
Fleet telematics systems have evolved from providing simple vehicle location information to producing pipelines of telecommunications and informatics data (for example, turn-by-turn navigation and vehicle diagnostics). In addition to these types of telematics systems, CETECOM performs telematics testing on infotainment systems (for example, music streaming and Bluetooth connectivity including data security) from a variety of tier 1 suppliers to the automotive industry. Our engineers will guide you through the telematics testing process.
You can trust CETECOM as the experienced expert to test and certify all your cutting-edge products.
OTA testing is a critical aspect of 5G device design and development. Beamforming, mmWave frequencies, and integrated transmitters are only some of the 5G NR technologies that can present testing challenges. Not for CETECOM: In 2019, we tested one of the first devices using a 5G-compatible antenna and have been growing our expertise in 5G Testing ever since.
LTE carrier aggregation allows operators to use multiple sub-6 GHz spectrum channels simultaneously to transfer data between base stations and a 5G mobile device.
Multiple spectrum parts that can be in the same or different frequency bands are assigned to one device to enable greater bandwidth and faster data speeds in challenging wireless conditions. These spectrum parts are called component carriers, and up to five component carriers can be combined to transmit aggregated bandwidth up to 100 MHz. Two aggregated component carriers are called 2CA, three component carriers 3CA, and so on.
CETECOM was one of the first labs in the world capable of testing the OTA performance of products using 5CA, the highest five-band combination.
In addition to CTIA-authorized OTA testing, our customers receive test results that are recognized by a wide range of network operators and global certification organizations, including the PCS Type Certification Review Board (PTCRB) and its counterpart in Europe, the Global Certification Forum (GCF).
