GUEST-LECTURE

IETE Students Forum at Dronacharya College of Engineering, Gurgaon organised a Guest- lecture on "Wireless and Mobile Communication" on 4th February, 2013. The invited speaker Mr. V. K. Arya (Retd. DDG, Ministry of Communication, Govt. of India, New Delhi) covered various aspects of Communication ranging from Analog, Digital, Satellite, Wireless and Mobile Communication.

Welcoming the speaker, Hon'ble Principal Prof. (Dr.) B. M. K. Prasad said that the field of wireless and mobile communication has a remarkable history that spans over a century of technology innovations from Marconi's first transatlantic transmission in 1899 to the worldwide adoption of cellular mobile services by over four billion people today. He reiterated that wireless has become one of the most pervasive core technology enablers for a diverse variety of computing and communications applications ranging from third-generation/fourth-generation, cellular devices, broadband access, indoor Wi-Fi networks, vehicle-to-vehicle systems to embedded sensor and radio-frequency identification applications. This has led to an accelerating pace of research and development in the wireless area with the promise of significant new breakthroughs over the next decade and beyond.

Presenting his views, the guest-speaker Mr. V. K. Arya expressed that wireless communication is the transfer of information over a distance without the use of electrical conductors. It is generally considered to be a branch of communications. It encompasses various types of fixed, mobile, and portable two-way radios, cellular telephones, personal digital assistants (PDAs), and wireless networking. As an expert, he also provided a perspective of the research frontiers of wireless and mobile communications, identifying early stage key technologies of strategic importance and the new applications. He discussed specific new radio technologies including dynamic spectrum access (DSA), white space, cognitive software-defined radio (SDR), antenna beam steering and multiple-input-multiple-output (MIMO) etc.

The lecture was highly informative and beneficial to the participants. More than 200 students from the Departments ECE and ECS actively participated. They understood the most important challenges related to the increasing use of wireless and mobile communication, and how this drives the need for advanced research. Through this lecture, they learnt various topics like Signal Processing, Channel selection, advantages and disadvantages of wireless LANs, Design Goals, infrared & radio transmissions, architecture of an infrastructure network etc. The student coordinators Ms. Saniya Puri and Mr. Kumar Rahul expressed their gratitude to the Guest speaker for sparing his precious time and enlightening them on wireless and mobile communication.
