Episode 8: Analog versus Digital Beamforming

We have now released the eighth episode of the podcast Wireless Future, with the following abstract:

The new 5G millimeter wave systems make use of classical analog beamforming technology. It is often claimed that digital beamforming cannot be used in these bands due to its high energy consumption. In this episode, Erik G. Larsson and Emil Björnson are visited by Bengt Lindoff, Chief Systems Architect at the startup BeammWave. The conversation covers how fully digital beamforming solutions are now being made truly competitive and what this means for the future of wireless communications.

One thought on “Episode 8: Analog versus Digital Beamforming”

  1. I don’t exactly recall where I heard this phrase, but I agree to its sentiment.

    “There is no Moore’s law for analogue”

    Looking back historically, a lot of radio-solutions has always started out as analogue, but over time shifted to digital solutions. In the early -00’s, people thought digital pre-distortion of power amplifiers was impossible due to the large oversampling – today it’s found in pretty much every single radio. The same thing with D/A-converters. A lot of hetero/homodyne radio transmitter designs are disappearing in favor of using high-speed DAC’s for direct-RF solutions. The border between digital and analogue is moving closer to the antenna every day!
