Wireless sensor based on LoRa technology
Pospíšil, Jan ; Krajsa, Ondřej (referee) ; Troják, David (advisor)
The bachelor thesis in theoretical part is focused on wireless technologies used for home control and automation devices where low power consumption is required. There are mentioned possibilities of each technology, energy requirements, range and throughput. The result of practical part is design and construction of a wireless temperature sensor which uses LoRa technology to communicate with a gateway and is also capable to last on battery for years. Additional feature is user possibility to use GPIO pins in form of relays. The task also covers design and construction of a gateway which listens for LoRa packets and communicates with PHP application on server side. Last step of practical part is focused on design of PHP application, which is responsible for visualization of received data.

LTE-Advanced/WLAN testbed
Plaisner, Denis ; Staněk,, Miroslav (referee) ; Miloš, Jiří (advisor)
This thesis deals with the investigation and assessment of communication standards LTE-Advance and WiFi (IEEE 802.11n/ac). The EVM error parameter is examined for each standard. To work with different standards a universal workplace have been proposed (testbed). This universal workplace serves for adjusting transmitting and receiving means and for processing signals transmitted and interpreted. Matlab was chosen for this work, through which only control devices such as generators and analyzers from Rohde & Schwarz. This workplace also measures the coexistence of these standards. At the conclusion of this thesis, different coexistence scenarios were designed and evaluated through testbed results.

Data Processing of Captured Radio Parameters in LTE-A System
Kupka, Lukáš ; Hošek, Jiří (referee) ; Mašek, Pavel (advisor)
Diploma thesis is focused on an analysis of radio conditions of indoor LTE-A mobile networks. Measurements of the Huawei LTE-A radio access network were performed using the R&S TSMW spectral analyser. Results have been processed and discussed. The practical part of diploma thesis also consists of a development of a program for processing the data sets obtained from R&S TSMW spectral analyzer.

Measuring of Key Parameters of Experimental LTE-A Mobile Network
Bednář, David ; Mašek, Pavel (referee) ; Hošek, Jiří (advisor)
The thesis is about measurment of experimental mobility network LTE-A setwork parameters on BUT in Brno. In the first part there is born of LTE network, which continues with general architecture of mobility and experimental LTE-A network. Together with thesis there is a description of measurment machine, with which was measurement provided. The result of thesis is created web application, which behavior is compress of measured values of LTE network parameters and create universal graphs.
