RF Electronics & Wireless Communication

The lab is an integral part of ‘Prof. L. R. Gadre Wireless Complex’. A high frequency signal generator (4 GHz) and spectrum analyzer (6.7GHz) have been purchased through the donation from the Gadre fund for carrying out advanced research in RF Electronics & Wireless Communication. A Spread spectrum based modular Wireless link set-up at 2.45 GHz for Bluetooth, CDMA, WLAN applications, is being built at the lab. This will help in understanding  and characterization of each block in a wireless communication link for the best performance.

A modular system for a 'Telemetry link for navigational aids' has been developed. This link based on RF communication can serve as a low cost telemetry system for automated or semi-automated control of Radars on an air-base.

Research is also being pursued towards development of surveillance/counter-surveillance gadgets and in the field of RFID technology. Readers for RFID tags in the ISM band in UHF range is being developed.

On the Academic front:

The wide-range of experimental facilities, enable  the students gain a deep insight into the design and working of, various analog and digital modulation systems and signal transmission through various transmission media. The lab is an integral part of the course  'Communication Electronics' (course code-EE405). It provides the necessary infrastructure for the EE405 course projects, which are mostly in the area of RF/Wireless Communication.

The lab is also meant for teaching the fourth year undergraduate students of electrical engineering about the practical aspects in the design and working of basic and advanced communication systems through the course Communication Engineering Lab (course code-EE455).
