Do exceptional weather conditions significantly impact operation of radio modems in the 2.4GHz band?
It is a scientific fact that RF energy loss in free space (atmosphere) during exceptional weather occurring anywhere on earth is negligible in either the 2.4GHz or 900MHz license-free ISM bands. That said, customers do experience weather related communications interference such as antennas flexing with wind, moisture penetrating a coax cable, antennas encased with ice, moisture on foliage, etc.
