Title:
How much more bandwidth do we need in wireless?
Abstract:
The world is becoming increasingly digitalized and connected, and mobile broadband connectivity is the backbone of this development. The demand for capacity and expectations on service quality are constantly increasing, which calls for new wireless technology solutions. Much of the capacity improvements in past decades have been achieved by increasing the spectral bandwidth. 4G utilizes wireless channels with tens of MHz of sub-6 GHz spectrum, while 5G is envisioned to exploit hundreds of MHz in the mmWave bands. If we extrapolate this development into the next decade, it seems logical that 6G will require several GHz of bandwidth and operate in the sub-THz bands. But how practically viable is such a development and will it answer to the actual needs of society? Do we truly need more bandwidth or are there alternative solutions? These are the questions that will be discussed and answered in this keynote.

Title:
Accelerate Antenna Design Optimization Using Machine Learning
Abstract:
Antennas are a critical part of any wireless system for maximizing efficiency and data rates. Machine learning is a method of data analysis that automates analytical model building. Antennas are becoming more and more complex each day with increase in demand for their use in a variety of devices (smart phones, autonomous driving to mention a couple); antenna designers can take advantage of machine learning to generate trained models for their physical antenna designs and perform fast and intelligent optimization on these trained models. Using the trained models, different optimization algorithms and goals can be run quickly, in seconds, for comparison of different designs. This talk presents the process of fast and intelligent optimization by Design Exploration and machine learning. Examples to showcase the advantages of using machine learning for antenna design and optimization will be presented.
