Abstract Adaptive modulation is implemented on a wideband OFDM transceiver prototype to quantify its performance in indoor wireless environment. Our measurements indicate that over a bandwidth of 100 MHz, the channel varies quite significantly. With a target uncoded bit error rate of 10 $^{-3},$ it is found that at link distances of 1.0 to 10.8 meters, the data rate varies from 395 Mbps to 76 Mbps. The measured adaptive average data rate is 2.88 times the average data rate without adaptive modulation. Furthermore, the adaptive modulation is 8.9% of the entire transceiver modem which means it is of low complexity
