Maurice - Buildings are built to 'float' literally, in big concrete 'boats'. Perhaps your civil engineers were a little backward. The bullfighter isn't saying that it isn't possible; he's just saying it effects the economic crossover point. Certainly you would agree that it is less expensive to build a sky scraper on Manhattan (granite bedrock) than in Montreal (no bedrock at all - they literally freeze the soil and float the buildings (at least according to the tour guides ;))). Clark PS One point that needs to be made is that telephone poles ain't exactly easy to put up in sandy soil either, so sandy soil penalizes both options to some degree.

Maurice, Great rant, it was worth waiting for. Minor disagreement though. >>But you'll notice in the USA that the economics of PCS [=2GHz] is proceeding very happily. Capacity is the key. While the basestations are more closely packed, they provide access for more subscribers so they end up fully used anyway. As you tried to say, they also have higher data rates available for a given bandwidth.<< I don't believe data rate per bandwidth has anything to do with carrier frequency. The modulation is done at a lower "IF" frequency and then upconverted to the transmit frequency. You don't send any more information with 5Mhz of bandwidth at 2Ghz than 800Mhz. Please enlighten me if I'm wrong. I do have a degree in trees, but I've made my living in communications for the last 20 years. Pete

Your floating foundation is what the guys that are more engineers than civil, call a raft foundation. We used them for instance in the Niger Delta where the soil is predominatly soft ground. That's a cost justified for a self supported microwave towers not for a monopole. Maurice if we have to contract all those expats to build the damn poles' foundation we incur in severe costs. We have a profit motive as much as the tree man from Alaska have. Moreover we don't have in the Chechenia's of this world the subcontractors just across the street. Maurice I'm talking about the real world. You are not very successful in persuading me that CDMA will mena a different INFRASTRUCTURE than the TDMA thing.
