    2828I am currently studying the experimental effects of radio frequency attenuation on modulation coding schemes on the ORBIT test bed. I expect that coding schemes with greater spectral efficiency are, by nature, more susceptible to signal degradation. My current setup uses the ''iperf'' utility and establishes  one WiMAX radio node as a client and one WiMAX base station node as a server. My data seem promising, but I am trying to investigate how to raise the envelope.
