Actual RF range performance is sugject to a number of installation-specific variables including, but not restricted to ambient temperature,
relative humidity, presence of active interference sources, line-of-sight obstacles, near-presence of objects (for example, trees, walls,
signage, etc.) that may induce multipath fading. As a result, actual performance varies for each instance.
