WIRELESS NETWORKING CONCEPTS 2
Question 1.
Cell splitting is the process of sectioning an overfilled cell into minor cells. Every cell has its
own base point and a consistent decrease in antenna height and spreader power. Cell splitting
surges the volume of a cellular structure as it rises the number of times that channels are
recycled. By outlining new cells which have a reduced radius than the initial cells and by
mounting these microcells among the prevailing cells, volume upsurges owing to the extra
number of channels for each unit area (Barnes & O'Farrell, 2016).
The magnitude of the cell splitting is that the frequency task has to be reused again that disturbs
the adjoining cells. It also upsurges the handoff rate since the cells are now minor and a mobile is
probable to cross cell borders more repeatedly matched to the case when the cells are large. For
the reason of different signaling circumstances, this also disturbs the traffic in control channels
(Huang, & Gao, 2014).

(i). Cells with small radius.
The structure would be as displayed in figure 2. The minor cell radius describes large populace
in the region and so the need for extraordinary capacity. For example, town region. Base stations

are positioned at the three of the six cell pinnacles with sectoral antennas for intense volume
(Wright, 2018). With such arrangement, cell splitting can be effected with growing demand to
increase the size. Also low power is indispensable for broadcast lessening the co-channel
interfering due to high frequency reprocess. For that purpose, the best structure for urban zones.
(ii). Cells with large radius.
The arrangement would be as displayed in figure 3. The higher cell radius defines lower
inhabitants in the zone rendering to low volume. Base stations are situated in the center of the
cell with omnidirectional antennas for concentrated capacity. High power is crucial for broadcast
due to long distances tangled. Co-channel intrusive is trivial here as base stations are far away
from each other and also the frequency recycle is trivial. For that motive, the best structure for
rural area or even portions of sub-urban regions Wright, (2018).
Aims for the Design.
i. Budget: The execution and running cost is insignificant for the cellular assembly.
ii. Communication power: Municipal districts have low transmission power due to
occurrence of several base points in the zone that assist to avert co-channel meddlesome.
Country side zones have regulated base points hence transmits at a higher power to
warranty coverage.
iii. Frequency use again: Frequency recycle in municipal district is high equated to sub-urban
or country side counties owing to high demand for size Hardjono, (2015).
iv. Scalability: With intensifying demand for volume, its prudent to increase more base
points on the system deprived basically upsetting the prevalent base points Hardjono,
(2015).
