Hands-on learning system for Wireless laboratory courses

Alfred Breznik, Carlo Manfredini Emona Instruments

Challenge to be addressed:

The challenge for the teaching of Telecommunications in the undergraduate laboratory has always been how to cover the ever expanding field of important new topics whilst maintaining a solid grounding in the fundamentals, as well as how to do this without the need for excessive and ever increasing laboratory equipment.

Ideally the equipment needs to operate at a logical level which facilitates learning but without the need for lengthy setup time and without being too much of a ready-made experiment.

Methodology:

The ‘block diagram’ acts as the universal language of Telecommunications around the world. The math of telecommunications can be expressed in a block diagram representation. The elements of this representation can be readily understood as each component block of the system is a relatively simple specific function.

The same blocks appear over and over within block diagrams. The fundamental mathematical blocks: multiplier, adder, phase shifter, integrator etc appear in most block diagrams, and along with other more specific blocks are used to build up a complex mathematical system.

To address the above mentioned challenge and create some laboratory teaching equipment it was decided to have individual hardware modules which model the function of each block in a block diagram. These individual modules are patched together according to the block diagram of the experiment of interest. This would allow simple as well as complex systems to be constructed easily by simply following the block diagram.

The system can then model a block diagram of a communications system, or part there of, with real time electrical signals and the students can access signals at each and every block within the system. In this way they have control over every parameter and setting in the experiment. They also need to measure and adjust every parameter in the system.
