At 64QAM speed the usable throughput will be <br />~54Kbps. Calculations based on 5 Watts TX power at all sites. 4RF radios do adaptive modulation and will try to run as <br />fast as possible. At the faster speeds the radio has to run at a lower TX power. At slower speeds it can TX at 5 Watts. At <br />the top speed of 64 QAM the radio sensitivity is -103dB. LMR400 & LDF4-50A Cable and 9dBd Gain Yagi \ 5dBd OMNI <br />antennas were used for calculations. <br /> <br /> <br /> <br />The information contained in this document is theoretical and should always be tested with the actual equipment intended for use to determine integrity <br />of the RF link and data quality.
