  1. 26. A Study of Low-Power Wide-Area Networks and an In-Depth Study of the LoRaWAN Standard

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : LAGUSSON PETTER; NORDLÖF JOHANNA; [2017]
    Keywords : LPWAN; IoT; LoRa; SigFox; NB-IoT; Internet of Things; LPWAN; IoT; LoRa; SigFox; NB-IoT; sakernas internet;

    Abstract : Low Power Wide Area Networks (LPWAN) are able to combine long range communication with a low energy consumption sacrificing performance in terms of bit rate and message frequency. This thesis presents a general evaluation of the LPWAN characteristics and a description of the LPWAN protocols LoRaWAN, SigFox and NB-IoT. READ MORE

  3. 27. Unlicensed and licensed low-power wide area networks : Exploring the candidates for massive IoT

    University essay from KTH/Radio Systems Laboratory (RS Lab)

    Author : Daniel Sjöström; [2017]
    Keywords : LPWA; LPWAN; IoT; massive IoT; NB-IoT; eMTC; EC-GSM-IoT; SigFox; LoRa; LoRaWAN; LoRa Alliance;

    Abstract : In the Internet of things (IoT), many applications will require low-power and low-cost to achieve long lifetime and scale (respectively). These types of applications are referred to as massive IoT, as opposed to critical IoT, which emphasizes ultra-high reliability and availability and low latency. READ MORE

  4. 28. Wireless system design : NB-IoT downlink simulator

    University essay from Uppsala universitet/Signaler och System

    Author : Piotr Krasowski; Douglas Troha; [2017]
    Keywords : nb-iot; lte; lte-a; downlink; simulator; wireless;

    Abstract : The newly defined NB-IoT standard currently lacks a toolkit and simulator. In order to develop algorithms for this new standard there is a need for channels and signals as reference during tests. MATLAB is commonly used for testing LTE signals and therefore the toolkit was developed in this environment. READ MORE

  5. 29. Cell Acquisition and Synchronization for Unlicensed NB-IoT

    University essay from Linköpings universitet/Kommunikationssystem

    Author : Eskil Jörgensen; [2017]
    Keywords : Narrowband Internet-of-Things; NB-IoT; unlicensed; cell search; cell acquisition; synchronization; artificial fast fading; binary sequences; peak sidelobe level;

    Abstract : Narrowband Internet-of-Things (NB-IoT) is a new wireless technology designed to support cellular networks with wide coverage for a massive number of very cheap low power user devices. Studies have been initiated for deployment of NB-IoT in unlicensed frequency bands, some of which demand the use of a frequency-hopping scheme with a short channel dwell time. READ MORE

  6. 30. Designing Applications for use of NB-IoT

    University essay from Malmö högskola/Fakulteten för teknik och samhälle (TS)

    Author : John Tengvall; Dennis Wildmark; [2017]
    Keywords : LPWAN; Narrowband IoT; NB-IoT; Application Design; Software Development; HTTP; CoAP; Comparison;

    Abstract : IoT är en marknad som har växt fort under de senaste åren och skapat sig en egen industri. Kärnan i IoT är internetanslutningen och i många fall är mobil kommunikation den bästa lösningen för en IoT-produkt. Problemet är att det inte finns något självklart val av mobil kommunikation för användning i en IoT-produkt. READ MORE
