Calculating Wireless Gain

[elie]

hey guys
this is very important to me to know how to calculate the distance that a access point can get. plus how many obstacles
in my house there is 4 obstacle and about 40 meters
what can i do ?????
plz reply very important

elie,

The thread (http://forums.practicallynetworked.com/showthread.php?threadid=7370) that you hijacked is dead. The last few posts where not even answered. This new thread as been started since your subject has no relationship to the other thread.

There are also "common courtesy" aspects for others using these forums. So what that means... Unproductive postings (cross-posting, double posting, thread hi-jacking, etc.) ultimately degrade the effectiveness of the forums as an information source for all others.

I'm not sure there's a way to calculate wireless range with any degree of certainty. Obvious factors would be frequency, antenna size and orientation, transmitting power... As for obstacles, that's an even tougher nut to crack. Size, composition, orientation, content (wiring, sound insulation, etc.). Sprinkle in other possibles like interference from other sources, above/below grade location, and so on...

It's probably safe to say that any range advertised by the equipment maker is an absolute max, assuming perfect line-of-sight conditions. And since there have to be at least two nodes, the max range will be whatever the weaker of the two transmitters can manage.

I think you've got yourself a trial-and-error situation, elie.

Good luck!
