It is too early to say, with precision, how new millimeter wave spectrum allocations around the world, to support 5G mobile networks and other applications, will increase the total supply of wireless communications bandwidth and spectrum. But millimeter spectrum is going to be released for use by communications entities.
Some might guess that the new millimeter wave capacity will equal or exceed all prior wireless allocations yet made. There are tradeoffs: distance for capacity, generally speaking.
That noted, millimeter wave capability will boost typical access speeds up to an order of magnitude from 4G levels, as 4G ultimately will boost capacity more than an order of magnitude over 3G.
In fact, that is likely an extremely-conservative estimate of capacity gains. “You can take all of the useful spectrum we now use from DC to 30 GHz and drop it into the lower end of the millimeter-wave region and still have 240 GHz left over,” said Lou Frenzel of Electronic Design.
“The unlicensed band at 60 GHz contains more spectrum than has been used by every satellite, cellular, WiFi, AM Radio, FM Radio, and television station in the world,” some would say.
