ePMP 4500 Access Point wind loading
Ensure that the device and the structure on which it is mounted are capable of withstanding the
prevalent wind speeds at a proposed ePMP site. Wind speed statistics are available from national
meteorological offices.
The device and its mounting bracket are capable of withstanding wind speeds of up to 200 kph
(124 mph).
Wind blowing on the device subjects the mounting structure to significant lateral force. The magnitude of
the force depends on both wind strength and the surface area of the device. Wind loading is estimated
using the following formulae:
Force (in kilograms) = 0.1045aV

Where:
Is:

the surface area in square meters
V
wind speed in meters per second
Force (in pounds) = 0.0042

Where:
Is:

the surface area in square feet
V
wind speed in miles per hour
Applying these formulae to the ePMP device at different wind speeds, the resulting wind loadings are
shown in Table 26 and Table 27.
