Signal processing in ZigBee system
Miloš, Jiří ; Bradáč, Zdeněk (referee) ; Hanus, Stanislav (advisor)
Master's thesis The Signal Processing in ZigBee System is focused on properties of Physical Layer of ZigBee (standard IEEE 802.15.4 - 2003). The work consists of three parts. The first part contains common view on using and properties of ZigBee. The next part focuses on the Medium Access Control Layer and in detail on the Physical Layer. There described signal processing in the Physical Layer in individual radio bands. The last part of the project contains the process of modeling in the MATLAB for both models of system ZigBee (bands 868/915 MHz and 2450 MHz). The last part of thesis deals with the simulations of BER depending on Carrier-to-Noise Ratio. Also examined the coexistence of systems operating in the same or a nearby frequency band. Based on the results of simulations there are given recommendations for the use of the ZigBee system in minimizing BER.

Human activity detection in indoor spaces via WLAN network
Sekanina, Tomáš ; Vašina, Petr (referee) ; Miloš, Jiří (advisor)
Bachelor thesis represents possibilities of use WLAN network and standard IEEE 802.11n for object or human detection in a room with different scenarios. Bachelor thesis includes a theoretical description of WLAN network and family of WLAN standards IEEE 802.11 with detailed focus on standard IEEE 802.11n and its physical layer. Attention is also paid to the wave propagation inside buildings. It also includes description of measuring Wi-Fi INTEL 5300 NIC, CSI Tool 802.11n and controlling measuring NIC in operating system Linux. In practical part is demonstrated analysis of high-throughput packets using standard 802.11n. Results of measurement of object and human detection in a room are exported to programming language MATLAB and there are analyzed. Results of experiments are discussed in conclusion of bachelor thesis.

Implementation of the Standard IEEE 802.11ah for Transmitting M2M Data
Masár, Marek ; Fujdiak, Radek (referee) ; Mašek, Pavel (advisor)
This diploma thesis deals with the implementation of standard IEEE 802.11ah into network simulator NS-3. The first part of the diploma thesis describes M2M communication for which the standard IEEE 802.11ah would be suitable. M2M communication is being more and more used in the society, that is why there is an effort to develop a new standard for this type of communication. The thesis contains a description of this standard based on technical specifications brought out by the Task Group ah (TGah). Some changes have been made in NS-3 for the purpose of this thesis in order to support this standard. In the next part there is a created scenario with basic topology in NS-3 with usage of standard IEEE 802.11ah, in which the functionality of the standard is tested. The result of this diploma thesis is a description of the changes which have been made and analysis of the output files from the simulation.
