If any one can help me please post or pm me thanks Quote Link to comment Share on other sites More sharing options...
SomeoneE1se Posted February 6, 2008 Share Posted February 6, 2008 it hates water more then metal so keep that in mind but it also depends on how far it needs to go past the metal dirt should have no tangible effect and WTF PM?! Quote Link to comment Share on other sites More sharing options...
Sparda Posted February 6, 2008 Share Posted February 6, 2008 how thick the metal can be before there is a problem with connections. Any thickness. Quote Link to comment Share on other sites More sharing options...
insert handle Posted February 6, 2008 Share Posted February 6, 2008 Could you drill holes in the metal at strategic locations to allow the wave through? How big is a 2.4GHz wave btw? http://en.wikipedia.org/wiki/Faraday_cage Quote Link to comment Share on other sites More sharing options...
Sparda Posted February 6, 2008 Share Posted February 6, 2008 Could you drill holes in the metal at strategic locations to allow the wave through? You would probably have to cut a hole so there is a 'line of no metal' between the wireless devices. You could drill holes of correct size for the 2.4GHz spectrum to pass through but, unless you drill many holes, there would not be enough of the signal left for it to be usable.

sideboom Posted February 7, 2008 Author Share Posted February 7, 2008 well the metal is up to 1' thich and cant have holes in it ... i am working on something for a gas pipeline it verries from 5 foot of dirt to 20 feet of dirt. Quote Link to comment Share on other sites More sharing options...
SmoothCriminal Posted February 7, 2008 Share Posted February 7, 2008 You may be SOL. Are there any options of running cables? You could install another AP on the other side of the metal? Can you offer any clarifications of exactly what type of environment you need this in. I am used to metal covered buildings. The school I work at has tons of metal lockers and metal windows which equals shitty wifi coverage. We have had to install AP's to almost every room that needs coverage (we have a large tablet pc with projector program) which means that we spend a shit load for our limited wifi. You are lucky to get a few mb connection in a room next to an AP.

VaKo Posted February 7, 2008 Share Posted February 7, 2008 If your considering drilling holes to allow wireless, then drilling 1 hole for a wire and sticking another AP on the other side would definitely be a better plan. Quote Link to comment Share on other sites More sharing options...
metatron Posted February 8, 2008 Share Posted February 8, 2008 If your considering drilling holes to allow wireless, then drilling 1 hole for a wire and sticking another AP on the other side would definitely be a better plan. Wouldn't it be easier and cheaper to just run a wire for an antenna above the dirt. LMR 400 is cheap enough. Quote Link to comment Share on other sites More sharing options...

beakmyn Posted February 9, 2008 Share Posted February 9, 2008 Plasterboard wall 3dB Glass wall with metal frame 6dB Cinder block wall 4dB Office window 3dB Metal door 6dB Metal door in brick wall 12.4dB source: http://www.wi-fiplanet.com/tutorials/article.php/1431101 Soil will have an affect on the signal. It depends on the composition of the soil (trace elements, moisture, etc). Are you using a directional antenna and aiming it at an embankment? Typical wifi's have omnis so the signal is traveling in all diretions. I wouldn't go drilling holes as you'll weaken the structure, since you probably don't know whether your signal is vertically or horizontally polarized.
