Question 1.
Cell Splitting is the method of apportioning a jam-packed cell into trivial cells, with every cell its
distinct base spot and a compliant reduction in antenna capacity, length and communication
power (Obaidat, 2017). This magnifies the size of a cellular structure as it rises the number of
intervals that channels are recycled again
In the image below, sector attended by A is presumed to be overcome by traffic (Obaidat, 2017).
New-fangled base spots are as a result required in the region to amplify the number of channels
in the area and to decrease the region attended by the single base spot. To be precise, A is
constrained by six new microcells; B, C, D, E, F and G.

Question 2.
N=12 BW =30 MHz R=2 km
Control channels for each cell=10 number of operators for each channel=8
(i).
Reuse distance is givenby , D= √ ( 3 N )∗R
¿ √ ( 3∗12 )∗2=12 km
(ii).Modest channel=25 kHZ
Channel bandwidth=25∗2=50 kHz
Number of channels for each cell=30000
50 − ( 10∗12 ) =480
On the other hand all channels are multiplexed in the midst of 8 operators, for that reason the
number of concurrent calls supported each cell is
¿ 480
12 ∗8=320 calls / cell .
(iii)
Regular no of call request for each hour =60
1hr=60 x 60= 3600s
ƛ= 60
3600 = 1
60 requests/sec
Regular duration of a call =5% of hour.
