"Fixed" and "mobile" is something of an arbitrary distinction - or 
rather, a distinction that works in one direction only. You can deploy a 
"mobile" technology in a "fixed" configuration, but not the other way 

In other words, the blurring of the distinction in future will mean that 
"fixed" and "mobile" refers only to deployment decisions - is the base 
station communicating with devices that move around, or not?
