Question: A wireless communications system can achieve a theoretical maximum data rate of 5 0 Mbps using 1 6 - QAM modulation in a 1 0

A wireless communications system can achieve a theoretical maximum data rate of 50 Mbps using 16-QAM modulation in a 10 MHz channel and using a single spatial stream. What data rate could theoretically be achieved if the same system used 256-QAM in a 160 MHz channel and using four spatial streams. Explain how you got to your answer.
