Rysavy: How will 5G compare to fiber, cable or DSL?

With 5G now officially on the drawing boards, an obvious question is how will new wireless broadband networks perform compared to wireline alternatives such as fiber, coax or DSL? An even better question is what will these networks need to look like to provide sufficient broadband capability for a majority of customers, one that lets them cut the cord to their wired broadband connection if they so desire?

Untethered is better. We love our smartphones, tablets, Bluetooth headsets, wireless keyboards and mice, wireless speakers, and ever more gadgets that connect us to work, family, friends, entertainment, and emerging applications in areas such as health, education, and energy consumption. With 4G offering fantastic performance, many users are cutting the cord to their wired broadband connection, electing for one monthly broadband bill instead of two.

Rysavy: Efficiency of spectrum use

Although technology has brought marvels in mobile computing, it has provided means to use all of the radio resources on which mobile computing depends. Wireless networks are a hundred times faster than just ten years ago, but their rich, interactive, streaming-oriented applications consume all available capacity and demand more. Managing this critical radio resource and determining the most effective spectrum-allocation policies require an understanding of what constitutes the most efficient use of spectrum.

Rysavy: Vehicles and mobility are converging but fragmentation, lack of standards may hinder progress

Two extremely common activities that people engage in are driving and interacting with their mobile broadband devices. Although sometimes people do both at the same time, these have largely been two separate industries. Now they are converging--one might even say they are on a collision course, although avoiding collisions is actually one of the primary objectives for people working in this industry.

Rysavy: Spectrum sharing with LTE is conceivable but not trivial

It sounds so appealing. You have a valuable resource but you don't need it all the time. Why not let somebody else use it when you're not using it? The resource in this case is spectrum, and the primary user for the bands under consideration is the government.
