As mobile systems gear up to adopt 5G wireless specification, the RF Front-End (RF-FE) control requirements pose several challenges. The complex RF-FE architecture of 5G radios not only demands dynamic configuration changes, but also requires that the configuration changes be achieved within a much shorter time window. While MIPI RFFE℠ has served the RF-FE control requirements very well over the past decade, MIPI RFFE 3.0 aims to meet the new 5G control timing requirements and adds several enhancements to the RFFE-Trigger specification. This presentation highlighted these enhancements to triggers, aimed at meeting 5G use cases.


Andrew Scott-Mackie, system engineer at Intel, has been active in wireless communications since 1998, working at companies such as Rohde & Schwarz, Alcatel-Lucent and Nokia. He currently works as a systems engineer in the Wireless RF division of Intel, with focus on control and interface aspects of RF transceivers, as well as the control of the RF front-end. Andrew is active in the MIPI RFFE working group, driving forward new features to address future control challenges, such as those due to 5G/NR. He holds a BEng degree from the University of Greenwich, England, in electrical engineering, and a master of science from the Technical University Munich in RF engineering.
