How 5G is Impacting OTA Systems
With 5G communication closer than ever, many companies are interested in new technologies that will help with over-the-air systems and communication. While most companies were more interested in using cable-based methods of sending data, 5G means that OTA will once again become very viable for these purposes.
One company that seems to have a prominent position with regards to OTA testing is the Wireless Telecom Group. The company recently showcased their new OTA system at the IMS 2018 event. It is a very unique OTA test system, which is using a noise source, test chamber and antennas. There is even a spectrum analyzer.
Calibrated Noise Source
The system in question uses a calibrated noise source for OTA testing. The idea is that a noise source is perfect for such a calibration process, because it has the calibrated data points to properly showcase air path loss, antenna efficiency and other vital information.
Antennas and Power Dividers
Two devices that are vital for such systems are antennas and broadband power dividers. With the OTA test that was performed by the Wireless Telecom Group, a Vivaldi antenna was placed inside the chamber. It has the purpose of being the receiving antenna. It is connected to a power divider, with one of the outputs connecting to a peak power sensor and the other to a spectrum analyzer.
Months of Testing
The coming six to nine months are expected a lot of OTA testing for companies in the communications sector. As telecom companies are starting to roll out their 5G networks, it will be interesting to see how OTA fits into the entire operation. There is no doubt that demand for 5G, both from a mobile and home-based perspective, will be very high.
It is promising to be a complete overhaul of the way that we use the internet – and the speeds that we have come to expect.
