can i use two of this access point back to back (crossover cable)to work as a repeater attach to a 15dBi grid antenna.
This is only to provide a internet connection to a school on the other side of the hill???i know consumer grade access point tends to lockup ...i'm merely doing this for free to help those kids.i'm sure they wouldnt mind going up on the top of that hill once in a while to reset that thing  if you guys have any other ideas pls point me to the right directions...as i said low on budget middle of nowhere...thanks guys |

in the WDS mode. Of course, you still need something to send to this and something at the school to receive it.
Feel free to ask more questions if you need to...

Centerville, IN | Yes, yes the Deliberants. Worth the price and easy to setup. There is also a Deliberant forum at »www.deliberant.us/forums/ you need more help, or ask here.

thanks for the quick reply...wipop is a airpoint xo...the school has 2 computers,which ill probably just hook a wireless pci card(with 15Dbi antenna) and a network card and connect the second computer to that.
To save money i was also thinking of just buying a repeater with 15 dBi omni antenna...but i'm not so sure if the signal can be retransmit from the distance of 2km...deliberant is great but please keep i mind that $180us is alot of money...i know im asking alot but please just think basic...low on budget middle of nowhere..thanks everyone.

| You could use one Deliberant 2300 in router mode with a 20 switch and hook both PC's up to it. Simple and very cost effective. I am assuming you own the WISP and want to hookup the school. What are you using for your customers? Just use one of the radios you already use. I know it costs you a bit, but the money you spend to do it right will get you some customers in the end.

It probably has virtually NO output power...which is something that you will need for reliability. Look at the spec sheet...it says that it is for extending to the patio...or garage. How far is that?
Not meaning to be "harsh and cruel"...but if you expect a "toy" to do the job...well, it just isn't going to cut it. I understand that the Deliberant is $180 but if you but if you use the Dlink and it doesn't work, then you have spent $101 for nothing.
The real truth is that you should be using a Smartbridges device for this task. Everyone will tell you that it is best to stick with the same brand equipment throughout a network, as "interoperability issues" are sometimes a problem. But that is even more money...
That being said...you came to the WISP forum looking for advice...we gave it to you. Feel free to try your solution. It might work. Regardless of whether or not it works, come back and tell us what you did and whether it worked on not. Feel free to prove us wrong...there are others in this forum that use Dlink and make it work. Our objective here is to help you make it work...regardless of what hardware you use.
Believe me, we have all tried these things before and we know better than most the "grind" that it can be to get things to work. The bottom line is that you have to stick to it and make it work...no matter what it takes.

my dillema is not the school..I'm trying to come up with a solution that enables me to send signals over the
top of a small hill, and down the other side.Repeaters cut the signal strength in half and im afraid that the consumer grade repeaters are not strong enough even with a 15 dBi omni antenna.The distance between my ap to the hill is about 2km and from the hill to school is about 2-3km.Is there a repeater that would do this task using only an omni antenna???im kinda repeating myself,i'm not too familiar with repeaters...thank you again. |

From the help of this forum i was able to put up a 40 feet tower on a top of a building using a 2" pipe with 12 cables for support.Set the airpoint xo and a 15 dBi antenna on the top of it.Mounted a satellite on the top of that building,while working,no safety nets ,no safety cables and it's about 45 degrees hot outside..connected 20 clients using only a pci wireless card using a 14 dBi backfire antenna.Being said all that...is because i like what John has just said..."The bottom line is that you have to stick to it and make it work...no matter what it takes."
Thanks John lol!!! |

Actually, they cut the data rate in half...
You can do what you want to do, as long as both of the antennas "look" at the repeater and have sufficient signal strength.
Where is this school located? Town? City? Coordinates?

You need to take a picture of this "arrangement" and post them here so we can see.
While I support the "do-it-yourself' way of doing things. I am concerned that you may be getting a bit ahead of the "power curve" here.
Forty feet of two-inch pipe falling down is NOT a trivial matter...I know this for a fact!
So POST!

| yes i would love to post some pics here...i'll show u some of the crazy things we tried to achieve hehe!!! oh did i mention while putting up that tower and all that cables...there are power lines around us this kind of working conditions i can probably get sued in US if someone get hurt...but this is a third world country people don't mind get a shock of electricity sometimes in conclusion i think ill try to buy a repeater use a 15dBi omni, hopefully both side will be able to catch the signal...bytheway just to make u guys laugh a little...the repeater is going to be powered by a 2x20amp battery it will give us a few days to power it..since there is no power on the top of the hill,the battery needs to be replaced every few days by a newly charged battery..lol...no solar nor windpower(too expensive)
Always Live Life to the Fullest...Don't ever quit believing in yourself,
As long as you believe you can,
You will have reason for trying.
Thanks again guys. |

A high-gain omni is usually a very POOR choice due to it's thin disk of high-gain. It's only a few degrees thick so it's easy to be under or over that plane and not be getting good signal.
It is usually preferred to use directional antenna and 2 radio units at repeater stations.
If you must use a single radio and omni, then use a medium-gain omni since it gives you a broader beam. Then use high-gain directionals on the other ends to hit the omni. |

| We have had some successes with Dlink 900 + APs but not without modification (getting the soldering iron out). Have found much better results with Osbridge units for the extra money they make the service really work properly.
I would have thought that running an access point from a car / truck battery you would be able to get a week or more. I'm sure John G will chime in with some calcs
Good luck with your endevours

I was imagining that there was a road to the top, all the hills round my way are <70m |

The old 900AP+ was a good unit, 5V operation sipped power pretty lightly.
Recommend you look for "deep cycle" batteries. Car batteries are not built to be discharged very deeply, and will go bad quickly if you do that. For a dollars more you can get ones that can handle lots of full discharge cycles and you will save money in the long run by not having to replace them so often. Even your basic trolling-motor battery from WalMart would be a better buy than a car battery. They make gel-cell batteries for alarm systems and the like, those are also very good as far as money and light weight. |
