Topic: Power / sensitivity

The content of this topic has been archived on 4 Mar 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

We are very interested in using OpenWRT as it provides many useful benefits.

It is essential however that we find a box which is at least as powerful and as sensitive as the SENAO CB3+, which can put out 200mW AND has a sensitivity of 92dBM @ 1Mbs.

Can anyone tell me which of the available boxes are the most sensitive and most powerful?

And can you provide the figures.

Of most interest are the linksys wrt-54g(s) - anyone know how powerful / sensitive these boxes are?

Thanks a lot.

Why not just check the specs?. It's throwing an error right now but iirc -95dbm at 1mbs and output up to ~250mw, but note that you might fry the chip at that output. HW v4 uses the BCM5352 which I can't find the datasheet for but generally newer generations have at least the same sensitivity.

Having done wireless for over 10 years and run radios at up to 500mw, I've never found much advantage to going beyond ~100mw output preferring the more balanced approach of just increasing antenna gain if required.

the wrt54g(s) have ok xmit power but relatively poor rx sensitivity compared to other radios.

My adobe reader was v4 (ouch), ug'd to v7 and confirmed -95dbm.

Such as? -95 is not shabby. At least broadcom and marvell have the guts to publish their specs unlike atheros and prism (conexant).

The discussion might have continued from here.
