60mw vs 800mw no range diffrence?

[thescreensavers]

So yea I had a WRT54gs with the 7dbi antennas set at 60mw from the default 42mw. And Got good signal around the house, perfect.But If I go outside of my house right by the sidewalk the G router would die out. now with 740 more mw, it goes only 3 feet farther. The new router is a BUFFALO WZR-HP-G300NH.

I don't really care for the sidewalk having wifi but I thought I would have ton more signal. :hmm:

Doesn't work like that. The radios aren't are sufficient quality to output at that power. Also you're close to the legal limits at that. In fact off the top of my head you're over.

 

[thescreensavers]

^ It came stock like that I believe its 1000mw is the legal limit.

[spidey07]

But you threw a 7 db omni on it. At 1000mW that's an EIRP of 5000 mW. Outside legal limits.

 

[thescreensavers]

^ What? The 7DBI was on the Linksys router.

 

[spidey07]

It is your responsibility to stay within FCC limits.

 

[thescreensavers]

^ huh, do you actually want to explain instead of being stupid? The 7DBI antenna was on the Linksys which was at 60mw, the new router uses 2dbi antennas (most likely) with 800mw of power.

So again how come no range difference?

Dude you are being stupid, how about you dont break the law and expect help.

If you are using 800mw with 2dbi of gain thats 1.268 watts according to my calculations. Since the FCC limit from what i understand is 1 watt for wifi you are over that.

spidey07 correct me if i am wrong.

 

[spidey07]

It's under 4 watts EIRP. Sorry OP, I thought you were running 840mW with a 7 db omni.

Here's a handy calculator to check your effective power.

I already knew 40 years ago that the reall important variable of wireless' transmission propagation is Signal to Noise ratio (SNR) and Not the "Brute" force Power.

In current days, the vastly Ignorant society understands only Brute Power (even if it is a make believe as in the WWE).

In addition the MIMO enhancement to extending Power is a nice theoretical concept that does not really works well with the way it is implemented with the dud_N.

Thanks for not reading

Thanks for finally reading 😛

Thanks for the link, though I should not go over the Legal limit.

So I guess mw has nothing to do with the Signal length well maybe partly related? oh well, It gets all over my house I was just wondering why exactly.

So SNR and actual Antenna (dBi) combined with the mw relate to the distance? or is there something else to factor in other then walls?

 

[spidey07]

Signal to noise ratio is really what's most important. Signal power drops inversely with the square of the distance so it drops off rapidly. The main reason is the walls/bricks of the home will block most of it. It's also the quality of the radios.

I've got a Cisco 1252 at my home and I get good signal to noise 100+ yards away outside.

It the quality of the Radio which includes the basic circuits, the Output Amp., the Antenna and its matching impedance to the output stage.

All of these are not really designed "Badly" in the Entry Level Wireless hardware (as oppose to the real Cisco. Not Linksys Cisco).

Marketing Verbiage is Not a substitute to good technology, and as long as the End users will focus on the "Stupid social aspects" of the technology it will just get worse.

ubiquity i think sells a router with mini-pci-e cards run 400mw so you could do two 5ghz and 2 2.4ghz or 3 5ghz and 1 2.4ghz or 4 4.9ghz (if you are authorized emergency personnel).

Think about a pyramid 100000watt amp out see at the flea market, then think about the 35 watt ppi from days gone by. it is the quality of output not quantity that counts.

With multiple radios you can do a mesh network or just buy a mesh network rig (Cheap google it) it makes alot more sense.

you relay on multiple channels and/or bands to have the goodness of WDS but without the bandwidth decay
