Answer 1
Cell splitting: Cell splitting can be described as a process which involves the division of
radio coverage of a particular cell site into a wireless telephone system into minimum two cell
sites. Cell splitting can be performed in order to provide additional space within a particular
region of the actual cell site. Cell splitting can also be described as a phenomenon of subdividing
a particular congested cell into various smaller cells (Gharipour & Liew, 2016). These cells have
their own base stations along with a corresponding reduction in the height of the antenna. The
implementation or execution of cell splitting helps inn increasing the capacity. Besides various
advantages, cell splitting provides some disadvantages as well, the limitations include handoffs
being very frequent, assignment of channels are difficult to perform and all the cells are not
allowed to split in a simultaneous manner, for this reason special care needs to be taken for
proper allocation of the problem.
In the figure that has been provided below, the zone that is attended by A has been
assumed to be overloaded with a huge level of traffic. Various new base positions are needed in
that particular area in order to gush the channels that are available in that region; this would also
help in reducing the region that is served by a lone base station. Appropriately, A has been
confined by six microcells that are new; these microcells are named as B, C, D, E, F and G.

Answer 2
N=12 BW =30 MHz R=2 km
The number of control channel per cell = 10
Number of users present per channel = 8
(i).
Reuse distance , D= √ ( 3 N )∗R
¿ √ ( 3∗12 )∗2=12 km
(ii).
Simplest channel=25 kHZ
el bandwidth=25∗2=50 kHz
No of channels per cell= 30000
50 − ( 10∗12 )=480 channels
