Wireless data acquisition in industry environment
Macura, Jáchym ; Kubíček, Michal (referee) ; Kolouch, Jaromír (advisor)
In the first part of Bachelor thesis is discussed selecting an appropriate standard for wireless data acquisition in industrial environments. In the next part are described the properties of the selected standard ZigBee. The next part is used to introduce and comparison of different ZigBee modules, which are available. In the practical part is represent transmission chain and its description. In the last section of Bachelor thesis are measured results.

Technology of Receiving of Very Weak Signals from Interplanetary Spacecrafts
Špaček, Jiří ; Bezoušek, Pavel (referee) ; Kovář, Pavel (referee) ; Kasal, Miroslav (advisor)
The work deals with the problematics of receiving very weak radio signals and it is focused especially on systems for low rate telemetry with carrier-subcarrier modulation. The part of this work is dedicated to calculation the link budget of typicall telemetry data transmission system between the Mars and the Earth in respect of the receiving equipment, which could be developed in the Experimental sattelites laboratory on the Institute of radio electronics BUT. The main part of this work is dedicated to developing and testing the low rate telemetry data transmission system model. The model is developed for the purpose of study the effects of AWGN and phase noise on the whole system and also on its component parts. The model has been developed and described in the way of easy parameters modification. The design for each parameter of the model is described carefully. With the developed model, the study of the effects of AWGN and phase noise on the whole system and also on its component parts has been performed.
