  • Point to multipoint cell plan and migration
    Publication number: 20060034207
    Abstract: The present invention relates to cell plans and cell plan changes in point to multipoint systems (PMP). A cell plan arrangement is provided comprising cells having four 90° sectors to which individual sector at least one of four orthogonal channels, such as channels distinguished by two frequencies and two polarisations, are allocated. A method is furthermore provided allowing gradual sector-by-sector migration into a 45° sector cell plan. The cell plan offers advantageous carrier to interference ration (C/I) improvements.
