First 5G Phone RF Modifications at Verkotan

Verkotan Olympus Digital Camera

Now that 5G devices are continuously increasing, we have expanded our service portfolio here at Verkotan to cover also 5G in addition to our 2G, 3G and 4G capabilities. Companies planning to jump in the 5G bandwagon or already being there, can use our services to make sure that their device is efficient and works correctly. This time we introduce our RF Modification services. Our Laboratory Manager, Miia Nurkkala, has provided answers to the questions.

What is RF Modification?

RF Modification is a test solution for 4G modem performance testing of smartphones, and now also for testing 5G modems in 5G phones, hot-spots, handsets and so on. See our page on the subject here: Phone RF Modifications

How the RF Modification testing is done?

The modification is done by bypassing antennas of the phones or other devices with coaxial cables. We test and identify technologies and frequency bands that are functional via each cable.  After this the modem performance can be easily tested without the impact of antennas.

Typically, as a verification process for the modification, we test RSRP responses from the different antenna branches to ensure that there is no gain in balance between antenna branches and that everything works like expected. MIMO performance is checked by comparing tested throughput against theoretical one. All this is done to ensure the high quality of our modifications.

As an example, we tested throughput performance rates of a 5G smartphone. The test was made in collaboration with Anritsu using their Radio communication Test Station MT8000A. We achieved throughput in the order 180 Mbit/s in SISO mode, 360Mbit/s in 2×2 MIMO mode and 720 Mbit/s when 4×4 MIMO was used.

Lastly, who needs RF Modification testing?

Mainly device manufacturers and operators. These companies can be for example companies making cellular testers or devices, infrastructure vendors and so on.
