A cellular communications network providing multi-hyperband capability comprises a mobile switching center acting as a data administration and call control center for a plurality of cells, each cell divided into one or more sectors. A plurality of communications links connect the mobile switching center to associated cells. Each sector is capable supporting one or more hyperbands. Entities representing sector-specific data are differentiated from hyperband-specific entities. Thus, a sector-related message transmitted via the communications links comprises a cell and sector number key and a plurality of parameters related to the cell and sector number, and a hyperband-related message transmitted via the communications links comprises a hyperband key, wherein the hyperband key corresponds to one of the supported multiple hyperbands, and a plurality of parameters related to the hyperband corresponding to the hyperband key.
