      It's not clear if you're entitled to monitor the cellular control
cqhannel under the ECPA.  Monitoring the voice channels is prohibited, but
the control channel may be OK.  An opinion here would be useful.

      Actually, it would be useful if someone monitored the control
channel in major cities and produced independent statistics on usage.
This would help in valuing cellular telephone properties and in
evaluating the validity of cellular operators requests for more
bandwidth.
