#Discussion(IoTStack) [ via IoTForIndiaGroup ]
The simulation is based on a request in a thread a about LPWAN on LinkedIn. A simulation of an LPWAN gateway on Mount Arapiles in Australia was requested.
It can be seen that at a distance of approx. 30 km the maximum range for indoor coverage has been reached. The town Horsham (1) is located shortly before this imaginary 30 km radius. The zoom view is showing that the color of the simulation changes from green to red with the construction line of the village. In the simulation it was specified that the maximum link budget of 158 dB 28 dB should be subtracted from the maximum link budget for loss due to fading and the first wall of the buildings. Since the simulation software knows the vegetation and the buildings, it uses a higher attenuation for the simulation for towns. If we calculate the maximum theoretical visibility at the beach in Australia with 364 m eye height and 1 m height for the antenna of the node, then we get 72 km. But in the simulation the radio wave reaches further than 72 km (3). The software calculates with the so-called radio horizon, which is on average 1.33 times further away than the visible horizon.The height of the gateway antenna above ground was set to 25 m before in other simulations. The height of the antenna at the sensor was set to 1 m. This 25 m height and on 1 m height repeat themself again and again in other of our simulations. This makes the simulations comparable. 25 m is a realistic practicable height for an antenna for a gateway.
