The correct answer is: B. Cell splitting
Cell splitting is a technique used in cellular networks to increase the capacity of a cellular network by dividing a cell into smaller cells. This is done by installing additional base stations within the original cell. The smaller cells have a smaller coverage area, but they can support more users.
Sectoring is a technique used in cellular networks to improve the performance of a cellular network by dividing a cell into sectors. This is done by installing directional antennas at the base station. The directional antennas focus the radio signal in a specific direction, which improves the signal strength and reduces interference.
Micro cell zone concept is a technique used in cellular networks to improve the coverage of a cellular network in areas with a lot of buildings or other obstacles. This is done by installing small base stations in these areas. The small base stations have a shorter range, but they can provide better coverage in these areas.
Scattering is a technique used in wireless networks to improve the performance of a wireless network by scattering the radio signal. This is done by using materials that reflect or scatter the radio signal. The scattering of the radio signal can improve the signal strength and reduce interference.
In conclusion, the correct answer is: B. Cell splitting.
