Depends...if these areas are small and surrounded by places
where cell phones/pagers/etc flourish, there's just about no 
way. You're also going to have a problem with cellular 
detection in that only law enforcement is allowed to have 
devices that scan on those frequencies.  A better bet might 

not true.  if you have a business need for the equipment, you can get FCC permits easily.  examples of "business need" 
include cellular/paging service providers, "technical service organizations qualified to own such equipment as part of 
their legally authorized duties"**, infosec auditors / pen-testers, etc.  dealers like bander.com and grove-ent.com, 
and of course the FCC, can provide you with the necessary info.

you are more likely to meet resistance to use of scanners from local government entities.  ALOT of cities and towns in 
the US have local ordinances that prohibit the use of ALL scanners - especially while in moving vehicles.  most of 
those local ordinances do of course provide stipulations that allow permits for certain applications.  in practice, i 
have found that permits are rarely granted though unless you know how to apply.  you just need to talk to the right 
local officials, and make sure your permit application is properly worded and submitted.  

sometimes, you simply cannot get a local permit.  i hired a law firm to investigate the legality of these local 
ordinances, and they are convinced that the ordinances are unconstitutional (several times over).  they were more than 
happy to fight pro bono if the need ever arose.

merely be jamming them all, but that is also illegal under FCC
regulations.

again, not true.  lots of businesses in the US use jamming equipment, and it can easily be bought in the US.  check out 
Netline or Wireless Tech.  casinos commonly use "jamming technologies".  the FCC just has not yet specifically 
*legalized* jamming.

p.s.  I love the Internet.  great place to buy all sorts of neat electronic equipment.
