4×4 MIMO in LTE and 5G – the underestimated feature in mobile networks

Written by Michael Lorenz | July 4, 2018
Updated by Arnd Sibila | September 6, 2024

Network densification and the introduction of new frequencies are time-consuming and cost intensive. The implementation of higher-order MIMO features into existing radio networks, however, will boost peak data rates throughout the network and deliver an additional capacity gain. 4×4 MIMO is the current state-of-the-art approach to improve LTE and 5G networks.

Validating license obligations – converting network scanner measurements into data rates

April 11, 2023 | by Michael Lorenz

“In mobile communications, trust is good but measurements are better,” says Hubert Aiwanger, Bavarian minister for economic affairs, state development and energy. The German state of Bavaria ordered a fourth review of mobile network operator license obligations. The review focuses on how well operators met the minimum data rate of 100 Mbps on federal roads and selected railway lines.
