Question

What are the techniques which are used in improving coverage in cellular networks?

Answer 1

by the using if this method



Cell splitting:

Cell splitting is the process of sub dividing a congested cell into smaller cells, each with its own base station and corresponding reduction in antenna height and transmitted power.
Cell splitting increases capacity of a cellular system since it increases number of times that channels are reused.
By defining new cells which have a smaller radius than the original cells and by installing these smaller cells between existing cells, capacity increases due to additional number of channels per unit cell area
In this D/R ratio is kept constant and entire system is rescaled.
