|Webinar proceedings – In brief.|
5G mobile communication system is supposed to provide a perception of 99.99% connectivity. The essential requirements of 5G are higher throughput, enormous capability, energy efficient transmission, ultra-low latency, and support of rich multimedia applications. 5G cellular network has been tremendously used in automated vehicles, IoT applications, video streaming, mobile TV etc. To provide seamless connectivity, higher spectral and energy efficiency, device-to-device (D2D) communication has become a key technology in 5G. D2D communication helps in meeting various requirements of 5G. However, there are several challenges such as proper resource allocation, mode selection, device discovery, and mobility in D2D enabled 5G networks.
The event started at 10.00A.M with a welcome speech by Dr. Satheesha T.Y, Head, Dept. of Electronics and Communication. He welcomed the speaker of the event Mr. Pradip Kumar Barik, Honourable Pro-Vice Chancellor Dr. Suresh K.S, CMR University, Honourable Registrar Dr. Praveen R., CMR University, Dr. Jayaprasad M., Dean, School of Engineering and Technology, CMR University, Faculties and participants of the event.
The Honourable Pro-Vice Chancellor Dr. Suresh K.S addressed the participants with his inspirational words and briefed the importance this webinar during Covid-19 lockdown situation.
The Honourable Registrar Dr. Praveen R addressed the participants with his inspirational words and added a special mention to department of ECE for launching a wonderful program during this lockdown period.
Dr. Jayaprasad M., Dean, School of Engineering and Technology, motivated the participants by briefing the prominence of 5G in current technology.
Dr. Muralishankar R. Professor, Dept. of Electronics and Communication, who is the pioneer in organizing this event, briefed about the webinar to the participants and its significance.
The session was auspiciously started with an invocation song by Prof. Divyashree, Assistant Professor, Dept. of Electronics and Communication Engineering.
The speaker started his session by introducing the evolution of 5G. The basic differences between 4G and 5G architecture and features were discussed.
The webinar also included a discussion on the need of a new technology. The different applications of this new technology were discussed. The disadvantages of mmwave were discussed in detail..
The webinar also included key take way concepts such as channel models in 5G and signal to interference noise ratio (SINR). The simulation of SINR which was published by the presenter in one of his papers were shown and the explanation about the comparison of 4G and 5G SNR was given.
The participants were also introduced to LTE (4G) architecture and 5G architecture to bring out the main advantages of 5G over 4G. The presenter included two videos to show the difference between 4G and 5G technology which explained the comparison in more detail. Further, the session included the concepts such as efficiency, complexity and latency comparison between the two generations.
The types of D2D communication were outlined with the block diagram. The applications of D2D communication in 5G were discussed. The participants were introduced to a battery energy consumption model for active CUs and active DRNs. The results of his paper such as battery drainage of the users, receiving energy consumption, saved battery energy of the active CUs, saved transmission power of the base station, number of unserved users and comparison of energy efficiency were displayed and explained in detail.
In the end the discussion moved to the future research directions, the open issues in D2D communications, the challenges.
At the end of the session, the speaker addressed various questions from the participants on the topic of the webinar in Q&A session.
The webinar was concluded with vote of thanks by Prof. Swetha Vura, Assistant Professor, Dept. of Electronics and Communication.
