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.

Laboratory Demonstrator for LPWA Technologies Enabling the Communication via the Lightweight M2M (LWM2M) Protocol
Dvořák, Radim ; Štůsek, Martin (referee) ; Mašek, Pavel (advisor)
As the number of wireless devices rises, so does the demand for reliable data transmission. To ensure the reliability of data transfers with such devices, suitable wireless technology, and a suitable transmission protocol have to be chosen according to the device capabilities and requirements. This thesis describes LPWA (Low-Power Wide-Area) technologies currently available on the market, both on licensed spectrum and non-licensed spectrum, focusing on licensed spectrum technologies (Narrowband Internet of Things, LTE-M) and also commonly used M2M enabled protocols for IoT devices. Furthermore, it compares those protocols from the communication parameters and data traffic perspectives with focus on overheads that further increase the amount of data transmitted but are necessary to ensure reliable data transmission. Lastly, it focuses on LWM2M protocol describing it to the detail and describes an LWM2M C++ library created as part of this thesis. In addition, a laboratory demonstrator was created utilizing this library.

Simulation of H2H and M2M Communications in Mobile Network LTE-Advanced
Číhal, Josef ; Mašek, Pavel (referee) ; Hošek, Jiří (advisor)
This bachelor thesis „Simulation of H2H and M2M communication in LTE-Advanced mobile network“ focuses on theoretical study of H2H (Human to Human) and M2M (Ma- chine to Machine) communication in fourth-generation of mobile network (LTE/LTE- Advanced). It also focus on the influence of M2M communication to compliance with the agreed terms of quality of service (QoS) for H2H traffic. Based on the theoretical analysis was created model of H2H and M2M communication using NS-3(Network Si- mulator 3). Last part of bachelor thesis deals with verification of the functionality of created model through simulations focusing on the key operational parameters such as delay, throughput and load of base station (eNodeB).

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.
