   There are multiple ways.   
      
   Things like DSL modems actually have different line speeds that you can   
   select between when subscribing to the service.   
      
   Things like cable modems combine different channels and different   
   numbers of channels to make different aggregate bandwidth.  The system   
   controlling a CMTS node tells cable modems what channels they can use   
   when.  They simply tell your modem to use fewer channels if you   
   subscribe to a lower speed.   
      
   It's possible to rate limit people on the router without any knowledge   
   of the connection technology.  This is done by keeping a counter of how   
   much traffic each IP address has sent in the last second / minute / hour   
   / day / week / month, and use that counter to decide if the next packet   
   to or from that IP should be allowed through.  If you're under your   
   speed limit, the packet goes through.  If you're at or over your speed   
   limit, the packet doesn't go through (yet).

   They don't need to know where your signal is.  They likely want to not   
   deal with that.  They only care about where to send the monthly bill to.

   Maybe.  Maybe not.  Maybe not in the way that you're thinking.
