Abstract

Remote Educational Gateway for Radio-Communication Nowadays, experimenting with hardware in engineering laboratories provides students anopportunity to gain a valuable hands-on experience operating state-of-the-art devices.Hands-on experiments help students to efficiently digest theoretical concepts. It trains them torely on the facts according to physical evidence. Nevertheless, hands-on laboratories are oftennot affordable due to shortage of costly equipment and human resources for laboratorymaintenance and assistance. Simulators exploiting mathematical models can serve as analternative approach to assist students in theoretical principles; however, the vivid elementssuch as teamwork experience, real signal generation and observation, and operating withstate-of the-art electronic devises are eliminated from learning process. With continued development of information technology and mature communicationchannels through Internet remote labs may potentially overcome many constrains faced inhands-on laboratories (e.g., minimizing expenses, providing flexible lab schedule, and sharinglimited resources among multiple students). Even though only PC-controlled experiments canbe used in remote settings limiting experimentation options, however, the growing number ofcomplex hardware-based experiments with computer controlled features creates a niche forpotential use of remote experiments in various educational fields. This paper presents a comparison study among three different remote lab implementationoptions. The testbed is eComlab, a radio-communication remote laboratory system developedby authors. It has been offered in several courses at the department of Electrical and ComputerEngineering (ECE), University of Texas at San Antonio. The implementation options arediscussed as various evolutional stages of the eComLab, which changed from a simplesingle-user remote desktop application to a multi-user system architecture that operates as agateway connecting four remote sides: (1) PC-controlled experiment, (2) users such as students,(3) instructors and (4) system administrators. In its latest version, users may utilize regularweb-browser to access remote experiments, the gateway provides various popular modernnetworking media (e.g., discussion boards, chat rooms, and video streaming), it enables groupwork, automatic setting etc. The paper provides intervention data in classroom through the analysis of surveys collectedamong students. It also discusses challenges faced by users during remote experimentation.
