Wireless lighting control
Pilmajer, Pavel ; Novotný, Radovan (referee) ; Levek, Vladimír (advisor)
Thesis deals with the issue of lighting technology control using wireless technology. Thesis includes a description of current possibilities of control light technology, methods of digital signal transmission using radio waves and protocols dealing with this issue are described. This thesis also contains a park aimed at the selection of suitable electronic components including the design of individual electronic blocks and printed circuit board. The conclusion of the thesis is the realization of electronic modules, including the creation of module software and measurement of achieved parameters under real conditions.

Properties of the physical layer of ZigBee
Humpolík, Tomáš ; Frýza, Tomáš (referee) ; Prokopec, Jan (advisor)
The ZigBee standart works on using physical and data link layer of IEEE 802.15.4 standart. Three bands were defined (2.4GHz, 915MHz and 868MHz). There was also number of physical layers defined, each of them using one of the three bands and number of modulation and spreading functions. This thesis is focused first of all on specification 2,4GHz physical layer, which is world-wide used because this band can be used (with observace of the local rules) without license. Thesis is in its first part focused on modulation function, as well on used spreading functions and number of channels for each physical layer. In the second part is paid attention to demonstration kit by ATMEL Corporation, which enables associate a simple network in star topology and using the network for demonstration of simple functions of associated devices, and kit by Radiocrafts corporation, which is used in laboratory work. Laboratory work is focused on characteristics measurement during data transfer.
