Apni University
India’s No.1 Digital Book Compay
Preface
The importance of Wireless Mobile Network is well known in various engineering
fields. Overwhelming response to our last year exam sutra series inspired us to create
this book. This book is structure to cover the key aspects of the subject WMN.
All the questions in the book are very important for the upcoming MSBTE summer
2020 exam. All care has beentaken tomake students comfortable in understanding the
basic concepts of the subject.
The most important part of this kit is, we are not only providing the books but the
exams too at three different levels (basic, intermediate & advanced). The students
only need to study the book and co-operate us till exam.
We wish to express our profound thanks to all those who helped in making this
book realty. Much needed moral support and encouragement is provided on
numerous occasions by our whole family. We wish to thank the entire team of Apni
University who has taken immense pain to get this book in time with this quality.
Any suggestion for the improvement of the books will be acknowledged and well
appreciated.
