5G Security Aspects

5G is poised to bring many new services and applications to the telecoms and wireless industry. As a decentralized network concept, 5G components will be deployed throughout the network, each requiring strict adherence to security measures. In this short 8-minute video, wireless technology manager, Reiner Stuhlfauth, explains the key technology aspects ensuring 5G security.

5G Numerologies and Frame Structures

The 5G radio access network is designed to be extremely flexible, supporting different use cases including extreme mobile broadband (eMBB), massive machine type communications (mMTC) and ultra-reliable low latency communications (URLLC). Supporting opposing design constraints from high bandwidth to low latency, for example, 5G NR requires an entirely new frame structure to support these diverse… Read more »

Prepare your Spectrum for 5G Deployment

The rollout of 5G NR will initiate a worldwide deployment in an unknown radio environment where unwanted transmitters can degrade end-user QoE and in some cases cause outages of critical services. Prior to deployment, operators need to ensure the radio environment is free from interference by conducting spectral clearance and interference hunting. This webinar defines… Read more »

Demystifying 5G – Creating far-field conditions at short distances for 5G over the air testing

Over-the-air (OTA) testing for 5G NR devices usually results in high measurement distances – particularly for mmWave frequencies and massive MIMO devices. The video discusses various solutions to significantly reduce the measurement distances in order to achieve a compact test setup for mobile device and base station OTA testing. Learn more about software- and hardware-based… Read more »

Demystifying 5G – Over the air (OTA) testing for 5G NR in far-field and near-field

This video answers common questions that arise with 5G over the air testing. Where does the far-field start? Is the Fraunhofer distance “the” far-field distance? Do I need to know the antenna location inside the device under test? How can I measure under far-field conditions at near-field distances and remarkably reduce the test setup size?

Demystifying 5G – V5GTF crest factor reduction (CFR) – a simple way out?

A high peak-to-average power ratio (PAPR) is not beneficial as it challenges the non-linear power amplifier operation close to compression for maximum efficiency. A possible way out is to apply crest factor reduction (CFR) techniques such as to clip high signal peaks. This video demonstrates a simple method to clip (any) waveform, including the Verizon… Read more »
