Preface
We are living in the era of wireless communication. Everybody is rich or poor is using the wireless communication facilities like mobile phones. The difference is only in the type of handset and the services used by them but the basic concept of the technology remains same. EM electromagnetic waves which are used to establish the connection between two devices. Wireless communication technology has not only reduced the connection and communication time but also reduced the operating cost. When I was pursuing Bachelor of Engineering, it had been the topic of seminar presentation but today we are using that concept as a technology in our day-to-day life. This shows that how fast the popularity of this technology is increasing. Earlier wireless communication used to be a part in Communication System subject but now it is a complete subject in its own. The inspiration of this book comes from my teachers and questioning from my students enrolled in UG and PG programmes of engineering. The book contains the basic knowledge of wireless communication systems. This book is meant for the students who have basic knowledge of EM waves and their propagation. The book is as per the syllabus of some reputed government and private universities institutions. Readers are requested to give suggestions to enhance the usefulness of this book. Rajeshwar Dass

The subject of wireless communication has seen unprecedented growth within the last four decades and the trend does not appear to be anywhere close to so called saturation point. Every day the new technological developments are taking place in this field. This offers an ample scope to study, reflect and pursue for applications in teaching learning process and in pursuit of business enterprise. First and foremost being my firm in the Almighty for being a constant source of inspiration to me from the back of my head to whom I always beseech and seek his blessings. I thank the persons whose constructive suggestions during the course of development of this book helped me to crystallize the subject matter. My parents have been a constant source of inspiration for me. No words will be enough to express my thanks to them but I hope and wish to be always blessed by them. Seniors, peers and students contribute considerably to the development of the material for the book. They are too numerous to be acknowledged individually but I wish to put on record my gratitude to some of them. I am highly grateful to Er. Har Sarup Chahal, Hon ble Vice Chancellor, Deenbandhu Chhotu Ram University of Science and Technology DCRUST , Murthal, Sonepat for his support, guidance and blessings by agreeing to write the foreword for the book. I will be failing in my duty if I do not credit such personalities in the field of engineering like Dr. S.S. Pattanaik, Professor and Head ETV Department
