My ISP has already tried 128K wireless spread spectrum radio modems, and they work fairly well. If the Telcos move to raise rates, the internet will cease using the Telco system. And then some telephone interface company will create an internet to POTS (Paleo Obsolete Telephone Service) interface. The problem as it was explained to me is the aggregation factor (I don't remember all the details so the following information is from my bad memory). Back when, someone decided that 8 lines could be grouped, and 8 groups would form a trunk (or at some level), so any of 64 stations could make 8 (or 16) phone calls simultaneously into the central office. Really bad things happen when the 8 people are on for several hours and a 9th attempts to use it. To the point where you can't get a dialtone. And redial. Which uses more CO resources. Which causes more people not to get a quick dialtone. Which causes them to redial too... And then it melts down. (The time it takes to get dialtone is apparently a measure of load on the system). Telcos are like modern Banks - they are based on fractional reserve bandwidth. When everyone tries to use their share at the same time, you have the equivalent of a run on a bank. Didn't Adam Back suggest bandwidth based financial derivatives... --- reply to tzeruch - at - ceddec - dot - com ---
