For the maximum rated output power of the transmitter not listed in the table above, the isolation distance d, in
meters (m), is recommended and can be determined by the formula in the corresponding transmitter frequency
bar.
Note 1:from 80MHz to 800MHz Frequency on，Formulas with higher frequency bands should be used
Note 2:These guidelines may not be suitable for all situations，Electromagnetic propagation is influenced by the
absorption and reflection of buildings, objects and the human body.
