NB-IoT Coverage : Development of a measuring instrument for NB-IoT

Sammanfattning: This report is an exposition of the development of a measuring instrument whosetask is to map the physical coverage of the NB-IoT network. The measuringinstrument was developed on TietoEvry's initiative, as it was in their interest to obtaina measuring instrument that can be used to map the coverage in parts of VarmlandsNB-IoT network. Which in this way provides an assessment for any future projectsinvolving NB-IoT. The development of the measuring instruments you can carry withyou out into the field, uses a microcomputer for collecting measurement data savedin a log file using Python. The report also describes a complimentary program that inturn takes and visualizes the acquired data in the form of markers on a map, whichshows the signal strength of the NB-IoT network. The visualization program is writtenin Java and is based on the open source project: jxmapviewer2. However, themeasuring instrument as it is today needs further testing to ensure the accuracy ofthe measuring instrument. Something that can be looked over in the future.
