Way OT - Problems exporting technology: You know why WLL suffered in Asia? It has nothing to do with technology. The soil bearing capacity is 0.5 KG per square inch. Which means to construct the mast to put the antennas and the RBS for DECT, you would need a huge foundation. Not economic to do WLL. That's fascinating. I have read that the agricultural practices so wildly successful in North America don't work in Africa, in part, because of the different soil structure. Run a tractor over African soil and it compacts hard as concrete.

0.5 Kg/in2 are you kidding? You make it sound as though Asia is one big rice paddy of uniform soil strength. I can assure you they have multistorey buildings in many parts of Asia and those are not on floating foundations. If they want WLL they will be able to build it without much worry about soil mechanics. Neither are there trees everywhere, especially in towns where people live. Asia is a big place, not just the Mekong Delta, running from Istanbul at the most westerly, or maybe India depending on your preference, all the way to the tip of Alaska and down into the Pacific, usually to include Indonesia, Philippines and up to the Arctic circle. As you say, it is real life and each network has to be designed and built around geography, flora, buildings, people and economics. If the economics are there, big foundations are fine. Maybe where the subscribers can pay, the foundations are cheap too. It all depends on the real life situation in the particular location where WLL is considered. WLL doesn't have to be widespread like a cellular system. WLL subscribers use the system from one place. So a WLL system might be economic on one solitary rocky outcrop in part of Hong Kong and nowhere else in Asia and still make sense. It is very much a last mile technology as a wireline replacement. On the visual aesthetics of wireless towers, I imagine that locals in some countries might see having one as a source of pride. I remember when having a television aerial was a source of pride. Now they are just another nuisance in life. Same with cellphone towers. Soil mechanics? I thought you came to clean up the rot. What do you think of the chip rate argument? Maurice
