If you have implemented a cellular antenna within your device, your device may require certification.
You will find below some helpful guidance and advice on how you can go about the certification process and where Antenova can help.
Over-the-air testing is an essential element of any successful project and can help projects avoid costly delays. Over-the-air tests seek to provide manufacturers with a representative view of how a device will perform in the ‘wild’. The tests identify the impact of noise and detuning, the quality of the RF impedance matching and efficiency. RSE, TIS and efficiency are just three of the measures that carriers will assess.
Anechoic testing facilities are ideal to run these tests. In addition, the use of phantom body equipment can be used to truly assess the impact upon performance that users will have on handheld and wearable devices.

Pre-compliance testing is the best way to ensure a device passes all relevant certifications first time. Even for devices using Bluetooth or WLAN, testing can be worthwhile to diagnose potential performance issues before they manifest themselves. It is vital this is conducted as early into a project as possible. By identifying issues early on, it avoids the need to delay and/or redesign elements of the product to enable effective performance.
Mobile network operator approvals are essential for all devices using the cellular radio spectrum. The exact requirements differ per carrier and per market. For example, in the US, passing standards are more stringent than other regions.
Cellular network approval can cost tens of thousands of dollars per submission. A device that fails must be resubmitted, so pre-certification testing is essential.
Depending on the certification requirements, devices will need to undergo comprehensive testing. This can involve checking over-the-air performance, battery performance, cybersecurity, interoperability, hardware reliability and compatibility.
Testing a device early on can help save time and money further down the line. Submitting a device for certification shouldn’t represent a risk – pre-certification testing can give you an accurate indication as to whether the device will pass or not.
Antenova can provide help and guidance on testing, including initial Gerber file reviews and passive testing. We also have a number of partners who can provide full network certification.
