[FedCom] Federal User's Nextel/Sprint IDEN New Hybrid System

[Tom Greenwood]

Correct, Nextel IDEN is not any type of CDMA derivitive.  And you are also
correct that Nextel is an ESMR but only in the eyes of the marketers and to
the FCC for purpose of service classification. To those responsible for
monitoring network performance and the build out of these networks, that
distinction really does not matter.  They are just another wireless service
provider that is mass marketing wireless services to the general public.
Their only distinction which is quickly disappearing is that they have
historically served a niche market by providing push to talk type service.
Also, keep in mind that the term cellular has been terribly misused by the
marketeers.  The term is a definition that applies to how the network
topology is deployed, small "cells" covering defined areas and employing a
concept of resource reuse, be it either, frequency, timing, or a hybrid of
both.

I knew that CDMA uses "built-in" encryption but the Nextel iDen as I
know it, doesn't use CDMA. It's basically just like a regular trunked
system using TDMA and VSELP vocoder, etc. In fact, it's not even
considered a cellular company but an ESMR (Enhanced Specialized
Mobile Radio) system.
