Episode 3, Stefan and Bengt discuss why beamforming won’t stay analog for ever
Everything goes digital, why would beamforming be the only technology that does not?

Digital BF the scalable Antenna Technology!
Traditionally when designing analog or hybrid beamforming solutions for mmWave the design has been targeting a single application. A certain antenna panel/array has been designed for a certain purpose, such as a handheld device, and if another mmWave transceiver architecture is needed for another application that needs more antennae, such as a fixed wireless access…

Digital Beamforming, the power efficient solution for mobile devices!
We have in our previous posts shown the advantages with digital beamforming over analog beamforming from a performance point of view. Then one may ask; why hasn’t digital beamforming in mobile devices happened yet? Well, if you ask people in the field, they will say that a digital approach has way to high power consumption…

mmWave Radio design for mobile devices
Chips today for consumer electronics are practically all done using a technology known as CMOS (Complementary Metal Oxide Semiconductor, silica-based). However, for the high frequency parts in a radio transceiver which are present in all communication devices, another technology based on gallium compounds has been considered better suited in terms of high frequency performance. However,…

In how many ways can you hold a smartphone?
Did you know that people typically check their smartphones over 250 times per day? 80% check their phone when they wake up, 70% use their phone when in the restrooms and 40% look at their phone when driving despite it being illegal in most countries. From such data one can understand that with more than…
