Abstract:
A cellular network is a mobile network that uses a large number of base stations with
limited power to provide services, each covering only a limited area or cell. Limited
power allows the same frequency of multiple cells from a base station to be reuse
without causing interference, allowing a large geographic area covered by a limited set
of frequencies. The operation of the cellular network carried out in accordance with the
GSM network standard. Base station subsystems (BSS) are one of the key areas of GSM
network architecture and it is responsible for handling traffic and signaling between
mobile phones and network redirection subsystems. The performance of BSS can be
hampered in a variety of ways, including coverage issues, scheduling issues, fading
effects, power constraints, bandwidth limitations, and different protocols and standards.
As a result, the customers of the remote areas are unable to receive expected services
in a day. There has been a many more parameter on availability in cellular network,
however availability analysis from the academia and the telecom industry have used
different definitions for availability and the related concepts. In this project, constructed
different scenarios and region across the country calculated to impact of cellular
network availability on BSS networks infrastructure. The main goal is determining to
figure out network availability in daily weekly basis based on 2G, 3G and 4G each
technology comparison. The service availability differences in daily weekly basis based
on 2G, 3G and 4G technology of different districts of Bangladesh were also determining
here. For the data collection Huawei could in Huawei RTN 380 V100R007C00, RTN
905 1E, Huawei U2000 were used. The screenshots of different operations were
included here. Microsoft Office tools used to simulate the performance data. This project has been conducting to background research, network availability and future
innovation methods for the measuring network availability and applicable to the
Bangladesh telecommunications industry.
