Abstract
A cellular communication system is provided for transmitting a large number of highly directive personalized communication beams throughout an original geographic cell of the cellular communication system. The system advantageously utilizes a phased array antenna positioned at a center location of the cell in conjunction with a spread spectrum communications method which includes code division multiple access techniques for increasing user capacity. Each of the communication beams represents user signals assigned to specific users located within the original geographic cell and are adjustable in the user's directions. The total number of the communication beams may equal the number of users within the cell. An omnidirectional antenna is positioned in close proximity to the center location of the cell for transmitting and receiving an omnidirectional communication beam for communication with users located within approximately one half of a mile of the center location. A plurality of digital beam forming networks are employed for feeding the phased array antenna with the user signals forming the personalized communication beams.
