Car computer based on Raspberry Pi
Matula, Vladimír ; Dejdar, Petr (referee) ; Münster, Petr (advisor)
The main goal of this diploma thesis is to investigate the smart cars field together with the technologies linked closely to it. Further, the thesis offers an overview of options to extend the vehicle capabilities with the car computer created with the Raspberry Pi Zero W. The thesis provides hands-on experience and is stuctured into two parts. The first, theoretical section focuses on Internet of Things and Machine to Machine communication. It also describes the currently available smart car solutions on the market, their pros and cons. The practical part of this thesis describes design and creation of a smart computer based on Raspberry Pi Zero W with draft of self-made security system from vehicle containing a motion sensor and a camera. It also includes a development and integration steps with a mobile application capable of viewing the static information regarding the car state, such as Rotations per minute. Vehicle speed, etc. The created system also has the capability of informing the user about it's current location on request.

Universal Tester of Radio Conditions for Narrowband IoT Communication Technology
Možný, Radek ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
Technology Narrowband IoT is a representative LPWA (Low Power Wide Area) tech-nology that due to its promising features aims for demands of the Internet of Thingsapplications for autonomous data sending from sensors in areas of poor mobile coverage.For such applications, it is beneficial to firstly map properties of communication technol-ogy in areas of intended use and evaluate whether or not is this technology applicable.This Master thesis deals with the design of the hand-held measuring device for evaluationof Narrowband IoT properties. The output of this thesis is firstly comparison of LPWAtechnologies secondly, design of the mentioned device and verification of its functional-ity. And in last part description of measurement of transmission delay for delay-tolerantapplications. Transmission delay is a critical parameter for delay-tolerant applications.Such an application can be, for example, smart electrometers for which there is definedmaximal allowed transmission delay of 10 seconds and therefore it is desirable to evalu-ate whether or not is the deployment of the communication technology Narrowband IoTsuitable in the intended area for delay-tolerant or even for delay-intolerant applications.

Multi-radio Tester Utilizing LoRaWAN and Narrowband IoT Communication Technologies
Novotný, Jaromír ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
This Master thesis is focused on the design and consequential realization of the Multi-RAT communication device. The theoretical part describes a comparison of two promising communication LPWA (Low Power Wide Area) technologies that are available to use in the Czech Republic. These technologies are NB-IoT (NarrowBand-Internet of Things) and LoRaWAN (Long Range Wide Area Network). The practical part contains a description used components, their consequential fitting and testing of designed printed circuit board of the device. The thesis also describes the implementation of software and realized measurement. Technical documentation of a device can be found in the appendix of this thesis.

Implementation of M2M Data Generator Utilizing Communication Protocol Wireless M-BUS in Smart Grid Infrastructure
Hudec, David ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
V rámci této práce byl vytvořen popis bezdrátového komunikačního protokolu Wireless M-Bus, zaměřující se zejména na datovou část tohoto protokolu, strukturu jeho informačních polí, režimy komunikace a další specifika linkové a aplikační vrstvy. Na základě tohoto výzkumu byl vytvořen softwarový nástroj v jazyce Java, sloužící jako generátor dat zmíněného protokolu. Pomocí grafického i textového uživatelského rozhraní program umožňuje uživateli vytvořit Wireless M-Bus telegramy s velmi vysokou úrovní detailu a ty následně s využitím některého z podporovaných hardwarových zařízení periodicky odesílat do Wireless M-Bus sítě. Dále byla navržena dvě kompletní řešení, využívající buď samotného bezdrátového IQRF modulu nebo jeho spojení s řídicí deskou UniPi Neuron. Oba návrhy byly zrealizovány, otestovány a jsou v práci detailně popsány.

Experimental Evaluation of IEEE 802.11ac/ad Wireless Technology Properties
Jošťák, Matej ; Mašek, Pavel (referee) ; Zeman, Kryštof (advisor)
This bachelor work is about experimental verification features of wireless network, with focused on high speed transfers. For measurement was chose standard IEEE 802.11ac/ad. In the theoretical part, we describe the Internet of Things and communications between devices, especially the M2M communication. Then in work follows the chronological description of standard IEEE 802.11. The practical part is about describing the used hardware, after which follow the detailed describe of theoretical and practical realization of application and measurements itself. The last part of work is about measured values, its evaluation and makes conclusions. In the inclosure are source codes of our applications and graphs.
