Even though WiMAX systems based on OFDMA employ the most advanced technology in terms of modulation schemes and advanced antenna systems, cell ranges are constrained by physical propagation characteristics in the aforementioned frequency bands. This is not an issue in high population service regions with high capacity demand where smaller cells are required to meet data density requirements. When subscriber densities are low however, larger cells would be ideal to distribute the sector capacity in an economically optimized way over a wide area. Larger cells can best be realized with the availability of lower frequencies. Access to spectrum below 1000 MHz for broadband wireless services would enable more cost-effective deployments in low-density areas.
