In the introduction of the thesis, the internet of things (IoT) is presented. Here, I indicate certain challenges of internet of things to which I provide and elaborate potential solutions. Following this, I present and compare various networks meant for IoT devices. I divided these networks into two groups, local area networks and wide area networks. The mentioned networks are as follows: Zigbee, Zwave, Bluetooth LE, 6LoWPAN, RFID, NFC, NB-IoT, LTE cat. M1, LoRa and Sigfox.
Following, is a presentation of the Narrowband-IoT network. I describe the properties of the networks, its possible Implementation as well as the network architecture.
Hereinafter I describe the operation of my application and all of its parts. The Application functions as a simple laboratory IoT platform with capabilities of expanding and connecting to other applications. Using this application, I have carried out measurements of the NB-IoT network in Ljubljana.
The results show the coverage of the NB-IoT test network in Ljubljana for a typical NB-IoT device. Because the NB-IoT network is supposed to have a better coverage than the LTE network, I compare the two in the following section. To make comparison of coverage simpler I have chosen to compare a NB-IoT device and a mobile phone with LTE network support. Form the conclusion it is apparent that the NB-IoT does not, as of yet meet the promised better coverage than the LTE network.
