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.

Implementation of the LoRaWAN Communication Technology Using the Network Simulator 3
Mašek, Petr ; Pospíšil, Jan (referee) ; Mašek, Pavel (advisor)
The diploma thesis focuses on the description of LPWAN (Low Power Wide Area Network) technologies for use in IoT (Internet of Things) communication scenarios. The theoretical part compares communication technologies operating in the license-exempt frequency band, i.e. Sigfox and LoRaWAN (Long Range Wide Area Network). Furthermore, technologies using the licensed frequency spectrum are discussed, specifically, attention is focused on NB-IoT (Narrow Band IoT). Emphasis is placed on LoRaWAN technology and the properties of the unlicensed frequency band below the 1 GHz, which is utilized by this technology. The practical part of the thesis consists of the evaluation of simulation scenarios using an integrated module in the simulation environment NS-3 (Network Simulator 3). Attention is focused mainly on the analysis of data transmission success using selected communication parameters of LoRaWAN technology. The obtained simulation outputs with a focus on mMTC (massive Machine-Type Communication) communication scenarios confirm the relationship between the number of end devices and gateways, communication distance and transmission reliability, or the limit value for the duty cycle.

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.
