The mmWave technology for 5G and beyond
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, … Read more
One of the key features of cellular communication is mobility – this allows a mobile terminal to move around between cells while maintaining an uninterrupted connection to the network. Mobility is important in mmWave communication too and particularly so if mmWave communication is to be successful in offloading traffic from increasingly loaded sub 6 GHz … Read more
The smartphone is in your pocket or on the table. Suddenly you hear a buzzing sound, you pick up the phone and check the chat message you received on your device. On average, a person does this procedure 250 times a day according to a recent study! This pick up the phone scenario is one … Read more
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 … Read more
5G, as well as previous generations of cellular communication, relies on standardized communication protocols for the interactions between mobile terminal and the base station. With new and evolved features, and support of higher data rates, the complexity of the standards has increased for each new generation of mobile communication. Previous generations of cellular communication standards … Read more
Innovation is the strangest mix of slow and lightning fast. The slow part is all the tedious research done in labs and at universities, the hard (and slow work) of specifications, and the macro trends building persistently. These are all necessary enablers, but are for the most time not recognized as groundbreaking inventions, even if … Read more
Many believe the main reason for introducing communication in the mmWave frequency range (24 GHz and above) in 5G-NR is to allow for use cases requiring Gb/s such as VR or AR use cases. It is true that such use cases require a lot of bandwidth not existing in current sub 6 GHz frequency bands, … Read more
