Range can be affected by other wireless systems!
Other, more difficult to detect factors to be excluded influencing the range are
caused by interference from other radio systems or if the radio changes over time.
Such influences, for example, can be station movements (swaying of the mast
assembly in the wind) or other environmental changes (vehicles, movement of
stored goods, movement of people). These factors can make a precise prediction
of the maximum range extremely difficult.
Effective path of radio waves is more significant than the actual distance!
Overcoming of maximum distances for a line-of-sight link is a scenario
completely different from use inside rooms or in the direct vicinity to competing
wireless technologies. In these types of scenarios the decisive factor is frequently
not the actual distance between the devices, but, rather, the effective path taken
by the radio waves for multipath propagation, along with the actual interference
present at the exact installation location. Under some circumstances, signal
quality may even be enhanced by increasing the distance between the devices.
