Otto Wireless Solutions specialises in wireless communication and antenna solutions. Over the years, it has been a leading supplier of GSM, LTE, GPS, Shortrange and Wi-Fi antennas in the South African market. Every antenna it introduces into the market goes through a rigorous and thorough testing procedure, carried out by qualified engineers in its laboratory.
The latest evolution of cellular standard has introduced the 5th Generation known as 5G. As technology is advancing, so too are the upper thresholds of transmission bands rising to meet customer connectivity demands, rendering previous industry testing standards, such as 3 GHz Vector Network Analysers (VNAs) obsolete. It is for this reason that Otto Wireless Solutions has recently invested in a new Keysight Vector Network Analyzer with an operating frequency range of 300 kHz to 9 GHz.

In addition to the out-of-the box capability, this small and compact device also allows for expansion up to 100 GHz performance, providing a future-proofed piece of equipment. With different types of calibration like Electronic Calibration (ECal) and Smart Calibration, customers can be assured that their antennas are verified. Otto Wireless Solutions has always extended free use of its laboratory to all its customers, and will continue to do so, now with extended capabilities.
By way of example, the reference test results in figure 2 show an Otto Wireless Solutions’ 5G antenna tested at 3,5 GHz, which is now a standard band for 5G networks in South Africa. The antenna tested, the 5G-MO-5, is a 4G/5G Omnidirectional antenna which comes with 2 x 5 m cable.
