Abstract
An antenna switching system for handling high traffic sectors in a cellular radiotelephone system. The system switches the cell'"'"'s base station transmitter to sectors that have more mobile traffic than they can handle. The additional transmitters increase the number of frequencies in the overloaded sector, thereby allowing a greater amount of mobile traffic to use the cell.
