Hi Hannu,

Is "handover" a necessary part of a mobility system?

What about an add/drop model where a mobile device adds a new base
station when it comes into range and later drops an old base station
that's leaving range? Is it impossible to design a system where the
mobile device can normally determine 10 seconds ahead of time that its
leaving the coverage area of a given base station? Need a mobile
station receive on only one channel at a time?

Regards,
Bill Herrin
