Traffic and Cell Splitting<br />
• The optimum size of a cell depends on the amount<br />
of traffic.<br />
• If all channels in a cell are busy, it is impossible<br />
for anyone to place a call to or from that cell. The<br />
user has to hang up and try again later. This<br />
situation is called call blocking and is obviously<br />
undesirable.<br />
• A more unpleasant situation occurs when a mobile<br />
phone moves into a cell that has all its channels<br />
busy. The attempt by the system to hand off the<br />
call to the new cell is frustrated by the lack of free<br />
channels, and the cell must be terminated, or<br />
dropped.
