Network Synchronization of 5G networks

The last blog post (Part 3) examined the first challenge of how you can measure and analyze 5G networks passively by analyzing synchronization and broadcast signals. In this article we address the challenge of timing alignment between 5G base stations as this has a large effect on inter-cell interference and consequently user experience.

March 21, 2022 | by Peter Busch

Commercial 5G rollout is happening now and more and more 5G non-standalone (NSA) sites are being deployed. Existing LTE infrastructure is being converted into dynamic spectrum sharing (DSS) hybrid sites supporting 5G. An increasing number of private regional 5G networks in standalone (SA) mode are going into trial phase.

The popularity of app services, particularly video streaming, among smartphone users is expected to result in a 10-fold increase in data consumption over the next five years. Most of today’s mobile data traffic is generated indoors and this trend is set to continue into the future. While indoor use certainly includes users’ homes, in this context it mostly concerns large offices, public buildings and commercial properties.

Understanding and troubleshooting interference in 5G NR networks

Understanding and troubleshooting interference in 5G NR networks

July 22, 2021 | by Manuel Mielke

Interference is a complicated topic with manifold root causes and impacts on network performance. So, let's try to simplify the topic of interference by giving it some structure. In our last blog posts about network synchronization we learned a lot about internal interference, which comes from the network itself e.g. due to a lack of time synchronization. Now let's take a look at the second type of interference. It is called external interference.

Network synchronization in the time domain (part 2)

March 5, 2021 | by Manuel Mielke

Network operators have to make sure that synchronizing their networks will not produce any interference. Synchronization can affect several levels, these include synchronization on a relative time base, which was part of the blog post part 1 and extend to synchronization on an absolute time raster. Why? You can read all about it in part 2 of our blog post.

Network synchronization requirements are as old as digital cellular mobile networks. As soon as cells have a neighbor relationship, network synchronization is mandatory in both the frequency and time domain. How does 5G NR with its extremely flexible specifications affect these synchronization requirements, and how can they be measured?

Code-selective electromagnetic field (EMF) measurements (part 2)

August 18, 2020 | by Manuel Mielke

In part 1 of this article series about the electromagnetic field (EMF) measurements procedures, we explained the different measurement concepts, namely the code-selective and frequency-selective method. Now, learn how the code-selective EMF method offers mobile operators and infrastructure suppliers the best trade-off between EMF exposure limits and optimized coverage and capacity.

November 19, 2019 | by Peter Busch

Commercial 5G rollout is happening, and the rate of deployment of 5G non-standalone (NSA) sites steadily increases. Each new installation needs to be verified to ensure correct network performance and quality of service. 5G site testing requires specialist mobile network testing solutions that meet the RAN architecture’s new demands, including over-the-air connectivity and KPIs.
