  1. 1. An evaluation of coverage models for LoRa

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

    Author : Felix Paulsson; Issa Bitar; [2021]
    Keywords : LoRa; LoRaWAN; IoT; Empirical models; Path loss; Attenuation; Coverage;

    Abstract : LoRaWAN is a wireless network technology based on the LoRa modulation technology. When planning such a network, it is important to estimate the network’s coverage, which can be done by calculating path loss. To do this, one can utilize empirical models of radio wave propagation.

    Keywords : Propagation Model; WiMAX; 3.5 GHz; Urban; Suburban; Rural area;

    Abstract : Nowadays the Worldwide Interoperability of Microwave Access (WiMAX) technology becomes popular and receives growing acceptance as a Broadband Wireless Access (BWA) system. WiMAX has potential success in its line-of-sight (LOS) and non line-of-sight (NLOS) conditions which operating below 11 GHz frequency. READ MORE

  5. 4. Methods for Path loss Prediction

    University essay from Matematiska och systemtekniska institutionen

    Author : Cem Akkasli; [2009]
    Keywords : path loss; methods; prediction; hata; walfisch; bertoni; large scale; radio transmission; urban; rural; models;

    Abstract : Large scale path loss modeling plays a fundamental role in designing both fixed and mobile radio systems. Predicting the radio coverage area of a system is not done in a standard manner. Wireless systems are expensive systems. READ MORE
