wrote: You see millions of cell phones; You see a LOT of problems? Oh yes, I certainly do see problems. They're well hidden and mitigated in various ways. For example, if the error rate climbs, the adaptive tx power control cranks up the power on both the handset and the cell site end. If it persists, you get disconnected. Rather than have the user sound like they're talking while gargling ball bearings, the cell site just pulls the plug. Incidentally, the tx power control algorithm is rather messy as it has to handle different data types, at different rates, all while doing its best not to drain the handset battery. One the cell site end, it's no better as the power consumption of a typical cell site is non-trivial. Problems? Well: http://www.roughlydrafted.com/2008/08/28/the-inside-deets-on-iphone-202-and-dropped-calls/ Hmmm... power control algorithm again. Todays typical cell phones run about 150mw max average power output (according to the FCC ID data). Some are even less. None are anywhere near the 600mw legal maximum. If they could, you would have a dead battery within about an hour. (Do the math). Back to wi-fi and your setup. Sure, you'll have fairly good preformance with a high power setup. 14 times the usual power is bound to do some good. However, I suspect your neighbors are not so thrilled and will probably also be shopping for higher power hardware. It will be like an arms race, where the biggest bomb allegedly wins. Dealing with mutual interference is no fun, especially with only 3 available non-overlapping channels. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
