Secondly, it's not "cell phones". It's Nextel, a hybrid technology
system that emerged from Enhanced Specialized Mobile Repeaters
(ESMRs) which were legalized for-profit entities to sell local
repeater service to small or medium sized businesses on a multi-user
basis. The only relationship that it has to real cell-phones is
that it uses cellular digital technology and is used for "chatting"
rather than dispatching.

Nextel uses Motorola's iDEN system for their network - a good
technical overview is available he
