First of all, all prays to Almighty ALLAH, who gave us the courage and patience to complete such an important task.
We are very thankful to our teachers, especially Col (R) Muhammad An war, HOD (FEAS) RIU. This project has been carried out under the kind supervision of Abu Bakr Khitran. .We found him a source of knowledge throughout the work. We would like to express our profound gratitude and special thanks to our project supervisor.
We are very thankful to our friends for their motivation and support during the work on this project. Finally we wish our entire class fellows, friends and our family members who extended their valuable support during work on this project and as well as those who remain unnamed.
The aim of final year project is to have solid hands on the practical work and to gain knowledge and expertise which would rather help us to do our outmost in our practical future life. It is a compulsory part for the completion of B.Sc Electrical Engineering. This script will provide an insight in to our project’s features, characteristics, its applications in our day to day life and enhancements that can be carried out. Along the way, it also provides its readers, a touch of GSM (global system for mobile communication) as the project is based upon the principles of GSM. This project is truly an application of GSM.
