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.

UDP Stream Test: Measuring latency and timely data delivery with uni-directional traffic

July 18, 2024 | by Anna Llagostera

Real-time applications often use unidirectional UDP packet streams sent from servers to clients or vice versa. The new UDP Stream Test can provide insight into detailed per-packet latency values and overall mobile network reliability to transport these streams seamlessly in such scenarios. This test can be widely parametrized to match real-world use cases with constant packet streams or varying load patterns.
