Reduced quality results in reduced speed.  In the best case, you have a
technology like DSL that detects the reduced quality, and dynamically
adjusts transmission characteristics to adapt.  In other cases, you have
a technology like Ethernet where misdetection of bits results in the
loss of a packet, and ultimately requires retransmission.
