Webinar: Radio Fundamentals for Cellular Networks

This webinar reviews the common principles that form the basis behind the design of cellular systems. First, the composition of the network and multiple access techniques are summarized. The radio interface protocols implemented between the Base Station and the handset are discussed. Various processes or interactions between the base station and the handset (e.g., fining of a base station and handover) are illustrated. Finally, key points of the webinar are summarized.

Webinar: Dynamic spectrum sharing- Driving 5G to scale

Previous generational upgrade cycles required operators to undertake the expensive, time-consuming process of spectrum refarming. But, for 5G, dynamic spectrum sharing allows carriers to side-step that process by transmitting LTE and 5G NR in the same band at the same time. DSS, coupled with the availability of compatible devices, will lead to widespread 5G coverage in 2020 and help ease the transition on to standalone 5G.

Webinar: 5G Evolution

In this webinar, we explore the evolution from 5G to 6G from a service, air interface and network perspective, as well as take a crystal ball perspective on what the future with 6G may look like.

5G NR Evolution- What is Dynamic Spectrum Sharing?

As of now all sub-8 GHz 5G NR deployments are based on Time Division Duplex (TDD) and therefore use unpaired frequency bands at the 3.5 GHz frequency range. Phase 2 of 5G NR network deployments, anticipated for mid-2020, will utilize Frequency Division Duplex (FDD) mode. Almost 90% of all spectrum is organized as paired frequency… 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 »
