Greetings,
I am working to generate a coverage map for a LoRaWan gateway installed on a water tower. As such, I have created what I believe to accurate params for two devices acting on the 915mHz fequency for this simulation.
g1 = txsite('Name', 'GW1',... 'Antenna', monopole,... 'AntennaAngle', 0,... 'AntennaHeight', (48),... 'TransmitterFrequency', 9.28e+09,... 'TransmitterPower', 2,... 'Latitude', 37.71705,... 'Longitude', -97.29048)n1 = rxsite('Antenna', monopole,... 'AntennaAngle', 0,... 'AntennaHeight', (1.8288),... 'ReceiverSensitivity', -27,... 'SystemLoss', 0,... 'Name', 'Node1',... 'Latitude', 37.72107,... 'Longitude', -97.26081)
I defined a propagation model using longley-rice. And the only reason I can think such a thing is beneficial; according to my limited knowlege of this fantastic software. It should be able to account for terrain data to build a coverage map for the region which has fairly flat terrain (Wichita, KS).
pm = propagationModel('longley-rice','AntennaPolarization','vertical')
I get a warning on the right letting me know this will generate 78K+ triangles. When I run this section it takes ages. As a matter of fact it has been running for the last 45 minutes, still no results. I can hear the fans spooling up and slowing down. But nothing. The remainder of my code is as follows:
ss = sigstrength(n1,g1)margin = abs(n1.ReceiverSensitivity - ss)link(n1,g1)coverage(g1, pm)sinr(n1)
