Now imagine someone sending a signal 2 mhz wide on 447 mhz not really cool for the rest of the Ham community. That is why we need band with limitation
Just because a signal is wide doesn't mean it's causing interference for everyone occupying the same frequency range. You could for example have multiple spread spectrum users occupying the same range and using a very wide signal and not be stomping on each other. The bottom line is that interference is mitigated, and spectrum is efficiently utilized.
