Conducted Transmit Power; Figure 15-Transmit Power Specification, 3.3V Mode - Motorola Orthus Manual

Conducted transmit power

Due to the EVM and side-lobe requirements, the maximum transmit power will vary with data rates. The figures
below shows typical transmit power for each transmitted chain for both 2.4GHz and 5.2GHz operation. The transmit
power listed here are characterized based on EVM purpose only. The final AP transmit power depends on the result
of regulatory test for each country.
As mentioned in beginning of the document, the radio has two modes: 3.3V and 5.0V mode. The transmit power for
5.2G is the same in both modes whereas the transmit power for the 2.4G band is boosted. The two tables below lists
the difference.
The conducted transmit power is specified as the power measured at the Orthus radio connector and not at the
antenna chassis of the AP. Average transmit power is a number typically seen when measured on an arbitrary radio.
The conducted transmitted power is subject to vary as defined by transmit power variation specification in section
