I think you are getting MHz and Mb/s confused. Based on the electrical characteristics, the IEEE uses modeling to determine the number of Megabits that can travel a channel which is based on several factors; one important one is encoding. The MHz rating simply states the electrical performance/impedance of the cable plant. The equations used for each speed of traffic can be found in the IEEE standards which include all of the pertinent information.
