Thread: New iPhone - It's Wonderful!

^ actually I understand it fine.
They don't handoff (at the expense of signal) to a nearby cell when a subscriber is trying to make a call and the channels are all full. In this case the strategy would be to dynamically borrow frequencies from nearby cells, however the more likely scenario is to block the call. If the QoS in that cell drops consistently (too many blocked calls) they sub divide the cell into micro-cells.

ps the textbook definition of "handoff" is "the procedure for changing the assignment of a mobile unit as the mobile unit moves from one cell to another"
