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.

Electromagnetic field measurements in 5G: Overview and concepts (part 1)

May 20, 2020 | by Manuel Mielke

Why are electromagnetic field (EMF) measurements critical for the widespread rollout of 5G NR, and how do you measure electromagnetic radiation? Learn more about the two fundamentally different EMF measurement procedures – frequency-selective versus code-selective – and the arguments in favor of the latter.

5G site testing and troubleshooting

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.

Spectrum clearance: Prepare your 5G NR spectrum for deployment

February 6, 2019 | by Peter Busch

RF interference is one of the largest contributors to poor network performance, manifesting itself in dropped calls and low data throughput rates. Explore how to prepare your spectrum for 5G deployment by starting RF interference hunting and spectral clearance in LTE networks with a more automated approach.

Interference hunting in cities: Choose angle of arrival over power

October 24, 2018 | by Jeremy Carpenter

The urban RF environment is very demanding – densely packed with a myriad of cellular and non-cellular transmitters, interfering emitters, and inconveniently located building. This post explains why it pays to focus on the angle of arrival (AOA) method regarding speed, accuracy, and effectiveness when hunting interference in urban areas.

PIM testing: Best practices in a nutshell

August 3, 2017 | by Yunuen Wagner

When it comes to PIM testing, the necessary steps to identify passive intermodulation (PIM) and locate its source are similar to interference hunting. In the end, PIM is an internal source of interference and can have a significant impact on network performance.

Identifying passive intermodulation

January 12, 2017 | by Yunuen Wagner

How does passive intermodulation differ from external interference? This article examines the differences and sheds some light on best practices that help field engineers to distinguish one from the other easily. As switching the site off is not always feasible, could the TX power be varied?
