Letters to the Editor Here’s a letter we received in response to a question posed in Pipeline’s "Broadband Soapbox." What to do with 100 Mbps? Because bandwidth needs have been so consistently underestimated in the past, there is a tendency to think that the need for more bandwidth is never-ending. However, the human body limits the maximum data rate that a subscriber can consume. The human eye is the highest bandwidth "input device." HDTV with 1080p is pretty close to filling this input device with the maximum bandwidth it can accept. In addition, after the long specification and adoption process (which is still ongoing) with HDTV, it is unlikely that we will see an even higher bandwidth HDTV standard than what is being adopted today for 20 years or more. Therefore, we can use the bandwidth of an HDTV channel as the maximum unit that can be `consumed’ by a single subscriber. The next question is how many simultaneous consumers per subscriber? Perhaps four simultaneous HDTV channels is enough. (Some have suggested that more is necessary to feed an HD-DVR while the subscribers are watching other channels; however, a DVR is not necessary with true VOD.) If we assume that one HDTV channel takes 20 Mbps, we obtain 80 Mbps. If we assume some simultaneous broadband netsurfing, music and VoIP, etc., we might add another 20 Mbps and we have reached 100 Mbps. It may be that we are coming to the end of the bandwidth road with DOCSIS 3.0. Hal Roberts
