Answer:

Cell splitting achieves capacity improvement by essentially resealing the system. By decreasing the cell radius R and keeping the co-channel reuse ratio D/R unchanged, cell splitting increases the number of channels per unit area. However, another way to increase capacity is to keep the cell radius unchanged and seek …

• In cell sectoring a single omni-directional antenna at base station is replaced by several directional antennas, each radiating within a specified sector.

  • By using directional antennas power is transmitted in single desired direction decreasing number of interfering co-channel cells and co-channel interference.

  • The technique for decreasing co-channel interference and thus …
