Cell splitting is one of the methods of increasing capacity of cellular system. explain briefly the method of cell splitting [2 marks] explain two (2) differences between hard handoff and soft handoff 4 marks] (ii) (b) a service provider is given license for total bandwidth of 5mhz and each subscriber requires 10khz bandwidth. determine the system capacity if the service provider implements a cellular system with 35 transmitter sites and cluster size of 7. [4 marks] consider a metropolitan city with total area of 2500km2 covered by a hexagonal (c) cell array with a 7-cell reuse pattern. the radius of each cell is 6km. the cellular system has allocated a total bandwidth of 25mh2 and a full- duplex channel bandwidth of 30khz. a total of 40khz guard band is used in fdma system, and there are total 16 control channels calculate (i) the number of cells in the service area hint: ap ao sin 30â°, op = ap cos 30â° area of a aob x ab x op and area ofhexagon = 6 x a aob] [5 marks] the number of channels without frequency reuse
