Enabling ACM with Adaptive Transmit Power
When planning ACM-based radio links, the radio planner attempts to apply the
lowest transmit power that will perform satisfactorily at the highest level of
modulation. During fade conditions requiring a modulation drop, most radio
systems cannot increase transmit power to compensate for the signal
degradation, resulting in a deeper reduction in capacity. The IP-20 is capable
of adjusting power on the fly, and optimizing the available capacity at every
modulation point.
