Re: Remember "3 town wisp setup" ?
Throughput is a factor of many things.
If you take any combination of these radios on the bench and test throughput you could get a good idea of what they do in the field IN AN IDEAL RF ENVIRONMENT.
In other words, you are right. If you take a good link at 5' and do the calculations to get the right antenna for the proper signal strenght you can effectively get the same link. Not taking into account the environment.
That is what fade margin is for. If you over-engineer the link a bit and get 10db of fade margin for a typical 802.11b link you should be good speed wise.
The more speed the greater the sensitivity needs and usually the more fade margin you want. That's why it's not a linear slope to get higher speeds. More like an exponential curve. |
