One-line summary

Return path noise in CATV networks is dominated by "noise funneling" (addition at cascade amps) and noise sources inside subcriber homes that can be only partially attenuated, and will be reduced if <500 subscribers are on one segment. Return path characteristics suggest that FDMA or FDMA/TDMA hybrid will be better choice than CDMA or pure TDMA for MAC on this shared backchannel.

Main ideas

Requirements: Programming model issues:


Good example of taking an idea to its logical extreme; some convincing arguments that some kind of investigation is warranted, but several things are glossed over:
