5G uplink and downlink communications demand significantly more radio frequency (RF) bands, and, in turn, the subcarrier spacing (SCS) windows among RF packets are significantly tighter. That translates to unprecedented requirements for tight timing precision and low latency. Development of the MIPI RF Front End Control Interface (MIPI RFFESM) v3.0 has been keenly focused on meeting this challenge and aligning to precisely where evolution of the 3GPP 5G standard has progressed today.
With its 1000x data traffic capacity-enhancing ability over 4G, the promise of 5G technology is set to herald a whole new era in wireless communications. Beyond delivering a richer and ubiquitous immersive multimedia experience, it is going to transform communication and control for industrial and automotive applications. The self-driving-car revolution is poised to use 5G as its central pillar. With an entirely new class of Internet of Things (IoT) devices using distributed wireless sensing and shared artificial intelligence (AI), it has already started harnessing the power of 5G. The true potential of 5G wireless technology is limited only by one’s imagination. Its scope is truly boundless. And, behind its far-reaching abilities lies the hidden complexities of wireless technology for which the MIPI RF Front End Control Interface (MIPI RFFE℠) specification is a key enabler.
