Abstract
The rapid growth of modern Radio Frequency (RF) and wireless communication systems requires experienced professionals in the RF and wireless areas. In the curriculum of engineering education, university departments are introducing courses on high frequency telecommunication or radio communication related courses to equip students for the needs of industry. Effective learning in education can only be achieved by combining theoretical course with the corresponding laboratory. Distant access of robot-supported laboratories through the Internet is an important and new issue in distance education. This study is an application of new technologies for active learning methodologies, in order to increase both the self-learning and comprehension of the students. This study aims to find out requirements and needs to be fulfilled in developing a robot-supported remote-controlled RF and wireless laboratory. Development and implementation of a robot-operated internet-based RF and wireless laboratory is described in detail.
Highlights
Wireless communications technology is one of the most rapidly growing disciplines in electrical engineering
The paper is organized in five sections: Section II introduces the problems and limitations of conventional Radio Frequency (RF) and wireless laboratory training and describes remote laboratory options to overcome these problems and/or limitations
Students need to measure the average noise power shown on the spectrum analyzer and calculate measure the signal-to-noise ratio (SNR) at the intermediate frequency (IF) output of the receiver (RX) Unit
Summary
Wireless communications technology is one of the most rapidly growing disciplines in electrical engineering. It is important to prepare both the undergraduate and postgraduate students for careers in wireless communication technology to meet the needs of the telecommunications industry. One of the objectives of the RF and wireless laboratory is to provide the students with hands-on laboratory experience which may include: Basic RF concepts. It is important to develop wireless and RF laboratory that will provide the opportunity to acquire both in-depth theoretical understanding and hands-on laboratory experience. A framework for the development and implementation of an intelligent robot assisted Java-based remote controlled RF and wireless laboratory, accessible via the Internet by means of a Web browser is described. The paper is organized in five sections: Section II introduces the problems and limitations of conventional RF and wireless laboratory training and describes remote laboratory options to overcome these problems and/or limitations.
