Examining 5g technologies for 5g network system design is ever-expanding with innovations toward mmWAve technologies as well as heading toward 6g devices. The difficulties in 5g network systems design lies in a few different facets but most particularly the concurrent demands of decreasing space necessities and device size while increasing data transmission rates and power. Power amplifiers can help resolve this issue; however, the design challenge they add is high with transmission line voltage demands and added crosstalk. 

5G mmWave Design

There are a few key areas of 5G milimeter wave designs that are of most importance and attention in the next generation of developments.  5G mmWave beamforming and beam management will continue as it brings enhanced reliability and performance in the mobile sphere. Things like multi-beam repetitions, beam failure recovery, and signalling overhead each contribute to mobile improvements in the 5G mmWave arena.

Thermal and power demands in 5G mmWave band devices are full of challenges, especially within that ultrawide bandwidth frequency range. Current trends in overcoming 5G mmWave challenges involve faster link feedback opportunities as well as utilizing smart device sleep configurations to save with power efficiency. 

Additionally, pushing 5G mmWave into Sub-6 GHz territories involves 5G NR scalable and flexible frameworks. With 5G mmWave frequencies enabling more strict latency or reliability requirements in industrial or biomedical applications, along with many other key fields, the frequency band is ripe for innovation.
