Abstract
A method and apparatus for a high-capacity cellular network by improved sectorization and interleaved channel assignment is presented. Data transmission over a cellular network is carried out by implementation of a sectorization scheme, called the Narrow-Beam Quad-sector Cell (NBQC) sectorization scheme, and the corresponding Interleaved Channel Assignments (ICA). The NBQC sectorization scheme calls for each cell of a cellular network to be divided into four sectors, with each sector covered by a 60 degree antenna. Use of the NBQC sectorization scheme allows for implementation of the corresponding ICA, in which assignment of transmission channels to each cell is based on a re-use factor of N=2. Accordingly, the interleaved channel assignments allow for the use of the transmission channels in cells which are adjacent in the cellular network.

12. An apparatus for a high-capacity cellular network, comprising:
-
at least one first cell sectorized into at least one sector; and
at least one frequency channel assigned to the at least one sector of the at least one first cell, wherein when the at least one frequency channel is assigned to at least one sector of an at least one second cell, it is assigned in an interleaved fashion to the assignment in the at least one sector of the at least one first cell.
