It won't be immediately obvious, but limited range isn't necessarily a disadvantage:  It may sometimes actually be an advantage.  The concept of "cellular" systems is that the same frequencies can be used 'nearby' (what constitutes 'nearby' depends on factors...).  A single city or suburban block could be served by one (or a couple) of cell sites.  
An old friend of mine (Who, like me, is a 'ham', an amateur radio operator) who was working on the problem for a company explained it this way:  There are certain frequencies which are fairly strongly absorbed by oxygen molecules in the atmosphere.  You'd actually benefit if you could place more (and very cheap) cells.   I'm talking about frequencies of about 60 gigahertz.    Extremely high frequency

Such frequencies, if used, won't interfere with terrestrial uses.
