Question 1.
The process of dividing overcrowded cells to inconsequential ones with these cells having
compatible drop in aerial height, separate base positions and power of transmission is called Cell
splitting (Andrews et al., 2016). As a result, the size of the cellular structure enlarges and
increases the frequency at which these channels will be usable time and again.
From the following figure, it can be understood that traffic at the zone of A will be very high and
saturated. Hence, change of base positions is required in such area for regularizing the channel
count in these regions as also in decreasing the regions that get served by that specific base
station. More precisely, six new microcells - B, C, D, E, F and G are surrounding A.

Nodes=12 Bandwidth=30 MHz Range=2 Km
Number of control channels∈each cell=10 user count∈every channel=8
(a).
Distance of Reusability−D= √ ( 3 N )∗( R)
¿ √ ( 3∗12 )∗( 2 )=12 Km
(b).
Simplest channel=25 KHz
Channel bandwidth= ( 25∗2 )=50 KHz
Channel numbers∈ every cell=( 30000
50 ) − ( 10∗12 ) =480 channels
All these channels get multiplexed between 8 different operators thereby making number of
supported calls for every cell
¿ ( 480
12 )∗(8)=320 calls /cell .
(c)
The Average of total calls requested hourly are 60
Since, 1 hour equals 3600 seconds,
ƛ=( 60
3600 )= 1
60 requests / second ,
the average time period of calls is about 5 percent of an hour Norris, (2019).
