Demystifying 5G

As LTE and LTE-Advanced technologies continue to be deployed, considerable attention is now focused on 5G, the next generation of mobile wireless communications. With huge improvements in throughput, latency and connectivity, 5G will be take the industry to new heights – and undoubtedly push the laws of physics once again!

Expert lecturer, Andreas Roessler, has compiled a collection of short videos on key 5G technology topics to get you up to speed quickly.

5G Requirements and Timeline

In this video we answer the questions: what is 5G, what are the targeted applications and resulting requirements and what is the anticipated timeline?

Limitations of LTE

What limitations of LTE have been identified from a waveform perspective and related to 5G? How do new 5G waveform candidates cope with these limitations?

5G Waveform Candidates

Comparison of an OFDM-based LTE waveform with 5G waveform candidates such as UFMC, FBMC, GFDM and f-OFDM.

5G Frequency Candidates

A future 5G mobile communication standard shall support among other things a feature defined as enhanced mobile broadband (eMBB). eMBB calls for Gbps peak data rates and hundreds of Mbps average user data rates. This requires wider bandwidths that are only available in the cmWave and mmWave frequency spectrum. What are the frequencies and frequency bands for 5G that are being discussed in the industry?

Signal Generation & Analysis of cm and mm-wave Frequencies

How does Rohde & Schwarz support 5G research activities at cmWave and mmWave frequencies? The video demonstrates high frequency signal generation and analysis using signal generator and analyzer solutions from Rohde & Schwarz.

2 GHz Modulation Bandwidth for 5G Signal Generation

Enhanced mobile broadband is a major topic in the ongoing 5G discussions, with peak data rates in the Gbit/s range and average user data rates of 100 Mbit/s. To achieve these data rates wider signal bandwidths of 500 MHz, 1 GHz and even up to 2 GHz are considered, only available at higher frequencies sub 6 GHz and beyond. To enable the industry to study wider bandwidths at higher frequencies, Rohde & Schwarz implemented a unique 2 GHz modulation bandwidth in the R&S®SMW200A vector signal generator enabling 5G signal evaluation up to 40 GHz carrier frequency.

How about 5G EVM measurements better than 40 dB at 28 GHz

The 28 GHz band is one of the 5G frequency candidates that gains a lot of attention in South Korea and the USA. Signal bandwidths of up to 500 MHz are under discussion. The R&S®SMW200A vector signal generator and R&S®FSW signal and spectrum analyzer from Rohde & Schwarz deliver the required performance for transmitter and receiver design and enable design engineers to measure signal quality such as error vector magnitude (EVM) of -40 dB or even better for wideband signals at cm-wave frequencies.

UFMC Signal Generation

How to generate UFMC signals? Universal filter multi carrier (UFMC) is one of the deliverables of the EU-funded 5GNOW project. Rohde & Schwarz implemented UFMC and other 5G waveform candidates in their signal generator and signal analyzer solutions. This enables researchers to compare waveform candidates with each other and their own proposals, perform hardware in-the-loop experiments such as analyzing the impact of non-linear devices (e.g. power amplifier) to the signal characteristics and optimize RF front-end designs.

UFMC Signal Demodulation

How to demodulate UFMC signals? Universal filter multi carrier (UFMC) is one of the deliverables of the EU-funded 5GNOW project. Rohde & Schwarz implemented UFMC and other 5G waveform candidates in their signal generator and signal analyzer solutions. This enables researchers to compare waveform candidates with each other and their own proposals, perform hardware in-the-loop experiments such as analyzing the impact of non-linear devices (e.g. power amplifier) to the signal characteristics and optimize RF front-end designs.
