[MLB-WIRELESS] WRT54G Bulk Buy - cheaper again!

[Rob Clark]

Nick,

The -83 (Minitar) vs -80 (LinkSys) means that the Minitar only needs
half (50%) of the signal strength that the Linksys does for the same
speed link. (-3 dB means 1/2 power).

So...as the Minitar also has 3dB extra TX power, that means on paper,
two Minitars will have double the range of two WRT54G boxes. Every extra
6dB buys you a doubling of range. The Minitars have 3dB extra TX and 3
dB extra RX so 6dB overall benefit.

However, don't interpret this as a black mark on the WRT54G: The primary
benefit of these boxes (to me) is the exciting firmware that can be
loaded in place of the manufacturer's original. That teaches them a
number of new tricks, and in many situations, that can be an
over-arching advantage. Maybe the ideal setup would be a (hacked) WRT54G
AP, and a bunch of Minitar clients? 

I am considering getting a WRT54G myself to experiment with.

Gday Rob
would the (-) 83dbm I got quoted by minitar sales seem like an accurate 
reflection of the receive sensitivity to you to you?

If so is that quoted 3dbm difference in theory mean double the 
sensitivity compared to the WRTs @ 80?

I ask because it might mean the minitars are still arguably a better bet

to use in making an AP esp in tough terrain

Regards
