CDPD: Sharing AMPS Channels
two types of channel hops:
n forced channel hop is the one described before: get out of the
way of voice channel that is about to be used
n planned channel hop: initiated by MDBS periodically. Timer
value typically set to a value less than an AMPS user’s
perception that the CDPD traffic is interference (“cross-
channel interference”?)
specifications are based on notion that CDPD users are
second-class citizens. However, if CDPD becomes
more popular, nothing prevents network providers from
dedicating channels to CDPD (except that as is, voice is
the big cash cow......)
