Safety communicator
Kuřímský, Lukáš ; Boušek, Jaroslav (referee) ; Šteffan, Pavel (advisor)
The bachelors thesis deals with the draft of a safety communicator and the prototype that is able to transmit a rescue signal from areas that are inaccessible or not covered with GSM signal. The project offers a detailed description of the functions of the individual components necessary for processing and transmitting of the signal. Furthermore, it discusses the methods of transmitting and focuses particularly on one of the forms of amplitude modulation – amplitude shift keying that uses a self-healing protocol. It partly deals also with the process of choosing and designing the test antenna and its tuning.
