Towards Extreme Band Communications

A rapid increase in the use of wireless services over the last few decades has led to the problem of radio-frequency (RF) spectrum exhaustion. More specifically, due to this RF spectrum scarcity, additional RF bandwidth allocation, as utilized in the recent past over "traditional bands", is not anymore enough to fulfill the demand for more wireless applications and higher data rates. The talk goes first over the potential offered by extreme band communication (XB-Com) systems to relieve spectrum scarcity. It then summarizes some of the challenges that need to be surpassed before such kinds of systems can be deployed. Finally, the talk offers an overview of some recent studies illustrating how different XB-Com technologies can collaborate to increase emerging and future networks' reliability and coverage while maintaining their high capacity.
