ACKNOWLEDGEMENT
I would like to appreciate and thanks Mr. Nizar Al Bassam for his support and help
during this period of planning stage. He guides me too much how to get the idea, how to
prepare the report, which books can be support my project& which internet source can be
support my project.
Also he is checking the format of report and each part which I wrote, always I
appreciated his time and patience as I have asked so many questions/ query. Also I would
thank Department of Electronics & Communication Engineering for supply the sources
which I required for this project (books, software).

ABSTRACT
This thesis discusses the In-building solutions which are implemented using the
IBS distributed antenna systems. These systems have been utilized in different sections
and proven to be quite efficient in optimizing the user capacity and quality of service for
a licensed spectrum. The implementation of the solution reduces the need for cabling and
power used during the transmission from one central antenna. RF coverage within
buildings is growing rapidly in telecom market in recent years. Demand for the wireless
users increased seemingly and now reliable communication is required in the offices and
residential buildings as per their business and personal requirements. Distributed Antenna
System (DAS) is used for the extension of and enhancement of mobile network coverage.
DAS is the topic of this thesis, the aim of which is to enhance DAS solutions for indoor
sites to improve the efficiency and maintaining the required Quality-of-Service (QoS).
Consider the radio part, it is indicating that by changing the antenna positions
with the help of simulation, efficiency can be improved. Ultimately, it appears that, both
radio and optical components, there is a higher limit of efficiency, that is, there is usually
the optimal number of antennas that provide the best results and consistent service quality
for the system. The objective of this project is to provide advanced coverage for the
buildings using different parameters selection and algorithm techniques. It will show the
real-time coverage for the proposed indoor antennas which will be connected through
different splitters and couplers using feeder cables. Gains and losses for each device will
be defined in MATLAB system to calculate link budget and EIRP (Effective Isotropic
Radiated Power) for the antennas. (Anon, 2018)
