Guarding and Securing of Objects and Areas Based on Arduino/Sigfox
Sadílek, Tomáš ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The aim of this bachelor thesis is to design and build a~guarding system using Internet of Things communication protocol. The system is based on the Arduino Nano developement board, the Sigfox communication module, and security sensors. The measured data are sent to the server, processed, evaluated and stored in MySQL database. When the alarm is triggered, the user is notified. The information is accessible to users on the web server.

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.

Implementation of Communication Technology LTE Cat-M1 Utilizing the Network Simulator 3
Drápela, Roman ; Jeřábek, Jan (referee) ; Mašek, Pavel (advisor)
Diploma thesis deals with the implementation of LTE Cat-M1 technology in simulator NS--3 (Network Simulator 3). The theoretical part of the thesis summarizes key terms concerning IoT (Internet of Things), M2M (Machine-to-Machine) communication, LTE (Long Term Evolution) and LPWA (Low-Power Wide Area) networks. The practical part summarizes the possibilities of currently available modules for cellular technologies for NS-3, ie. the LENA module and the subsequent extension of LENA+ and ELENA. Simulation scenarios offer a comparison of LTE/LTE-A and LTE Cat-M1 (also known as eMTC - enhanced Machine Type Communication) technologies for M2M communication. The results of the simulations are well-arranged in the form of graphs and discussed at the end of the thesis.

Mobile Application for Remote Measurement Support Using Sigfox Communication Network
Bulawa, David ; Strnadel, Josef (referee) ; Šimek, Václav (advisor)
The purpose of this project is the implementation of a mobile application for the operation system Android. The application supports remote metering via the Sigfox network and local metering via Bluetooth Low Energy. I implemented it natively in the Kotlin programming language using the Model-View-ViewModel design pattern. Measured values are collected remotely using the Sigfox REST API and locally using the Android Bluetooth library. The collected data are persisted in the local database on the mobile device. Then, the data is interpreted and visualized into graphs that the user can customize. The created solution provides a possibility to acquire, monitor and visualize data from sensors, including their historical values. The application is easy to use, but also allows configuring data interpretation and supports several different incoming message formats.

Implementation of the LTE Cat-M1 Communication Technology Using the Network Simulator 3
Maslák, Roman ; Možný, Radek (referee) ; Mašek, Pavel (advisor)
The Diploma work deals with the implementation of LTE Cat-M technology in the simulation tool Network Simulator 3 (NS-3). The work describe LPWA technologies and their use cases. In first are described the main parts of the Internet of Things (IoT) and Machine-to-Machine (M2M) communication. Subsequently are described and defined the most used technologies in LPWA networks. Technologies which are used in the LPWA networks are Sigfox, LoRaWAN, Narrowband IoT (NB-IoT) and Long Term Evolution for Machines (LTE Cat-M), where LTE Cat-M technology is described in more details. Simulations are simulated in simulation tool NS-3 and use LENA module. In NS 3 tool are simulated Simulations, which give us informations of Network state according to different Network set up. At the end are done changes of Radio Resource Control (RRC) states in NS-3 tool. These changes are required for correct implementation LTE Cat-M technology in NS-3 tool. Then we are able to simulate simulations, which meet to definition of LTE Cat-M technology.

Design of a current data logger for LPWA sensors
Mikulášek, Michal ; Možný, Radek (referee) ; Štůsek, Martin (advisor)
This Master thesis deals with the design and construction of a measuring device for measuring and the current consumption logging of sensors using LPWAN (Low Power Wide Area Network) technology. The theoretical part of the thesis firstly summarizes selected LPWAN technologies. Selected technologies, namely: LoRaWAN, Sigfox and Narrowband IoT (NB-IoT), are described more in detail. Further, the current measurement techniques are briefly discussed. The main focus is given to the current shunt measuring methods. The second half of thesis describes procedures conducted during the design and construction of a measuring device. The current measuring is based on the current shunt circuit complemented by the voltage amplification circuit, whose output is subsquently converted into digital form using an AD converter. The thesis describes in great detail the procedures for selecting individual components and important processes used in design of printed circuit boards. An integral part of the measuring device implementation is the design and implementation of control software, which is described in detail and supplemented by workflow charts underlining the entire description. The implementation of the entire measuring device is completed by the design and implementation of the cover box using 3D printing technology. Finally, the specifications of designed device are briefly discussed based on the limits of the used components.
