Preparation Strategies: Advanced Communications

UPSC will conduct the ESE 2023 exam in the next few months. It makes the remaining months until the exam date much more significant from the ESE preparation point of view. It is especially applicable for the subjects such as advanced communications. The updated ESE exam syllabus ensures that aspirants learn the latest communication technology. Advanced communications are one of the latest added subjects in the syllabus of ESE for Electronics and Telecommunication engineering.

The best part is that ESE aspirants can acquaint themselves with the latest communication technology after they build a decent conceptual base in this subject area. So, if you focus on this subject, you will observe a significant increase in the final marks scored in the Paper II of the UPSC IES 2023 for Electronics and Telecommunication Engineering.

The question paper creators add a decent number of questions from this section. So, one needs to be very selective before starting with ESE preparation. Experts always recommended ESE aspirants follow study material designed for UPSC ESE 2023.

 

But, if you still face a problem with some specific concept, feel free to refer to the following books:

1. Electronics communication system: By Wayne Tomasi. The book explains all the concepts starting from the fundamentals through the advanced communications concepts up to the data link layer.
2. Introduction to data communication and networking: By Behrouz A. Forouzan. This book is useful to learn certain critical topics such as security, application, and protocols.

These two books are enough to cover all the concepts related to advanced communications. To explain the ESE preparation strategy for this section, we have divided the subject into the following subparts. You will also find the detailed description and preparation tips for each topic in the following sections:

• Communication networks: Principles/practices/technologies/uses/OSI model/security.
• Basic packet multiplexed streams/scheduling.
• Cellular networks, types, analysis, and protocols (TCP/TCPIP)
• Microwave and satellite communication
• Terrestrial/space type LOS systems, block schematics link calculations, and system design.
• Fiber-optic communications.

Now, let us talk about the expert-recommended ESE preparation strategy for each of the topics mentioned above.

1. Communication networks:

• Communication networks are an important part of Electronics and Telecommunications Engineering. It includes sub-topics such as principles, practices, technologies, and uses.
• Apart from this, the OSI model and security are the more important parts of this particular topic. ESE aspirants must note that these topics are relevant for both ESE prelims and main examinations.
• Recommended book: Behrouz A. Forouzan’s Data Communications and Networking. This book explains communication networks in an easy-to-understand manner. It helps aspirants to remember the concepts quite well until the time of the final exam.

 

2. Basic packet multiplexed streams/scheduling:

• The basic packet multiplexed streams are a crucial topic from the ESE exam point of view. Therefore, you must dedicate certain time slots in your study timetable to prepare and score well for the ESE Main.
• If you want to build a strong base in this topic, you must refer to Data Communications and Networking. The electronics and computer science expert Behrouz A. Forouzan has used his extensive experience to author this book. This popular book is now beneficial for ESE preparation.

 

3. Cellular networks:

• This topic is associated with types, analysis, with protocols (TCP/TCPIP).
• You can refer to the books such as ‘Wireless Communications’ by Theodore S. Rappaport and ‘Mobile Cellular Communications: Analog and Digital Systems’ by William C.Y. Lee. You can learn the concepts well for the protocols topic with the book ‘Data Communications and Networking’ by Behrouz A. Forouzan.
• The experts frequently ask questions related to cellular networks in both ESE prelims and main exam. This indicates the significance of this topic in the UPSC ESE exam.
• ESE aspirants with an Electronics and Telecommunication engineering background must balance their ESE preparation with consistent practice of a theoretical and numerical type of questions. This step is critical for the ESE prelims exam. Therefore, you must ensure that you create a study schedule that helps you practice both these segments. It will help you secure the best possible scores in this section of the competitive exam.

 

4. Microwave and satellite communication:

• You must prepare this topic properly as it holds a weightage for both ESE Main and Prelims exam.
• As this segment of the competitive exam comprises numerical questions, it is important to practice such questions throughout the ESE preparation
• Microwave and satellite communication covers nearly 30% of the ESE syllabus.
• Therefore, you must choose the books such as ‘Satellite Communications’ by Timothy Pratt and ‘Satellite Communications’ by Dennis Roddy.

 

5. Fiber-optic communications:

• This topic comprises both numerical and theoretical type of questions.
• You must keep in mind that this topic holds 35% of the entire ESE syllabus.
• Fibre-optic communications are relevant for both ESE prelims and main exams.
• The most beneficial books to prepare topics under this subject category include ‘Optical Fiber Communications’ authored by John M. Senior. Apart from this, Gerd Keiser’s ‘Optical Fiber Communications’ will also help you to create the base required for this particular topic.

Thus, you can manage and learn the subject of advanced communications quite easily with the help of smart short notes. Here, you keep all your summary and important formulae from all the topics in form of charts and tables. Revising these short notes on the subject and appearing for online tests alone can help you score pretty well in the ESE exam. Put in the required effort as per the marks weightage and see your marks improve for the best.
