“The fifth generation (5G) cellular networks are coming,” explains Payam Heydari, a UC Irvine electrical engineering professor whose expertise is in the design and analysis of novel terahertz, millimeter-wave and radio-frequency integrated circuits, technologies that could revolutionize power-efficient wireless sensor networks.
As an IEEE Distinguished Lecturer for the Solid-State Circuits Society, Heydari spoke about the challenges and solutions of developing 5G technologies with engineering students and faculty at three East Coast universities: Lehigh, Princeton and Columbia.
“Millimeter-wave (mm-wave) and terahertz (THz) bands are underutilized regions of the electromagnetic spectrum that have generated a great deal of excitement for future systems that would be able to achieve very high speed wireless data transfer as well as wideband sensing/imaging applications,” Heydari explains. “The shorter wavelength associated with these bands is appealing since the physical dimensions of the antenna and associated electronics can be smaller, making it possible to design multiple antenna structures that can emit signals in various directions and even bounce off buildings.”
This is a crucial time in the development of 5G. “We are talking about what technologies will define this next generation,” says Heydari. “Will 5G be just an evolution of 4G, or will emerging technologies cause a disruption requiring a wholesale rethinking of entrenched cellular principles?”
IEEE Distinguished Lecturers are engineering professionals who lead their fields in new technical developments that shape the global community. They serve two-year terms and deliver lectures at chapter meetings and regional seminars around the world.
