[MLB-WIRELESS] WRT54G Bulk Buy - cheaper again! watch the version

[Simon Hall]

Rob,
Just bear in mind the versions of the WRT54G the version 2.0 has twice the
memory and a 200mhz processor I recall.  The v 1.1 has a 125mhz proc and
16Mb of ram??? I think that was the ram spec.  Obviously this limits what
software you can flash the unit with.  The subscribe version does all
versions of the WRT54G apparently.

Cheers
Simon Hall

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
