Roger Nichols has been directing Keysight’s 5G Programs for over four years. His 33 years of engineering and management experience in wireless test and measurement at Hewlett-Packard, Agilent Technologies, and Keysight spans roles in manufacturing, R&D, and marketing. He has worked in programs starting with analog cellular radio evolving to 5G and on every standard in between.  He spent seven years as the Senior Marketing Director for Keysight’s (Agilent’s) Mobile Broadband Division responsible for the wireless test-sets and systems used in all major design and certification labs as well as manufacturing facilities worldwide.

Rogers holds a BSEE from the University of Colorado, Boulder.

"5G: Finding an Antenna in a Protocol Stack: Challenges in the next phase of 
commercial antenna technology.''

The casual observer of the ubiquitous mobile telecommunications antennas now on towers, buildings, and disguised as trees and flag-poles pictures a simple monopole antenna much like we saw in the early days of 1G. But those who have to design, validate, install, and maintain these for a modern 4G network know the immense complexity of what hides within and around those simple-looking radomes. Dual polarization, local amplifiers, combiners to manage multiple bands and operators in the same radome, weather-proofing, lighting proofing, and the added complexities of diversity and the more complex low-order MIMO all implemented within stringent weight and wind-loading constraints have combined to make these innocuous poles into marvels of modern technology. The relentless pace of these technical changes is now adding even more dimensions to antennas for the sake of 5G. The addition of millimeter-wave frequency bands to mobile broadband communications now means high-gain antennas to maintain a workable link-budget. But this now means the resulting beam must be managed by electrical control, and since this control is part of media access, the antenna is now part of the MAC layer of the air-interface protocol stack. The same can be said of evolution of MIMO to what the industry calls “Massive”. So-called “massive MIMO” systems also have modes that manage the beams and MIMO management has always been an integral part of the air-interface protocol stack. This resulting tight integration of the antenna, the radio, and the protocol subsystem drives a complex set of issues related to measurement and validation. This talk will cover some examples of these, the latest moves in the 3GPP to standardize the approach, related and practical test and measurement issues, and a few items on a wish-list for the research community to tackle.
