一看你就是个半桶水。增加tx power确实可以改善range。但是一点点的增加基本没有 影响。us law怪定tx power只能在200mw以下,实际中要1000mw才会有明显改善。N66u 刚出来的时候就直接使200mw,后来asus改成了80wm,对range基本没啥影响,其实对绝 大多数人20wm就足够了。 ddwrt/tomato该tx power本来就是个噱头,developer搞这好玩的东西却你们给乱用了。 自己去看看tomato作者的解释吧 http://tomatousb.org/tut:increasing-wrt54g-transmit-power Now - first of all, let's get real about this "high power" crap. We are talking about a ridiculously smalll amount of power used in Wifi routers - I would normally even hesitate to refer to it as a transmitter - it is simply PUNY. The very term "HIGH POWER" to me conjurers up images of at least a 1, 000W transmitter, cooled by high speed centrifugal fans. That is 8,000 times more power than our little 30 dollar router, OK? Even a mobile phone runs 20 times the power! So - we are not talking here about running "High Power". We are talking about an increase from a puny amount of power to a *slightly less* puny amount of power. In this article I am not telling anyone to just go and use "higher" power, that would be against sound engineering principles and create a lot of problems in an already congested band. Higher power goes further and therefore potentially causes more interference to other people using the same channel. And not to mention in your country, it may be illegal. I'm just trying to dispel some myths which seem to have taken root over the years, which are just bloody ridiculous to a communications / RF engineer.
