Long range wifi?

Question

I would like to transmit a wifi signal 0.33km (as the crow flys)from my house to a other building. The houses altitude is 410ft whereas the buildings is 381, however there is still a large old building in the way (see picture). Is it possible to transmit this far with a cantena on the house and wifi cards in the building?

Answer 1

Well, probably not with the building in the way. You can use some decent OUTDOOR point to point units.
Like the ones found below

These allow you to mount the radio and antenna outdoors, like on the roof, bring ehternet into your system and then you will have a solid point to point connection. You configure one as an access point and one as a client poof coverage is done! No coax loss and very solid connections. We have used these at 2-3 miles with no problems, so 500 feet shouldn't be an issue.

You do need "Line of Sight".
You could try some 900 mhz radios which have slightly more "penetrating" value but not much - buildings (and trees) still have a blocking effect.

Answer 2

Firstly you need a clear line of sight so if the building is in the way it will not work. You could put a repeater on the building in the middle to receive and then send on the signal. Even if you have a cantenna on one end the other end with wifi card will receive the signal but not have the transmision strength to send it back again. Need cantenna on both ends. If you go down the repeater route you should use all the same brand of wifi routers to make sure they can use Wireless Distribution System (WDS). Some of the older Linksys routers can use the free firmware upgrades that support this. Search google for linksys firmware to find it and lots of helpful information.

Well you could use 2 parabolic or yagi antennas or even 2 homemade Can antennas but I don't know what to say about the obstacle in the way.How tall is it?
I think it may at least waken the signal.
The distance is not a problem because with e high gain unidirectional wifi antenna you could reach far greater distances.

Or you could install a solar powered wifi repeater un the building thet is in the way.I've seen a diy guide somewhere.

Answer 4

in case you're employing USB, the flexibility is constrained by employing the USB familiar itself. It in basic terms places out lots electrical energy. I even have an Alpha USB dongle that plugs into 2 USB ports for further ability, and an extremely large earnings antenna on it, and that i could be tricky pressed to make it attain a hundred and fifty yards except it replaced into throughout the time of an open container. My suggestion is to no longer USB for bridging the hollow, yet get something else. additionally, in case you're procuring from yet another united states, make beneficial what you purchase operates in a on the spot frequency it relatively is criminal on your united states. I stay interior the US and our Wifi is constrained to particular channels particularly 2.4ghz and 5ghz selection, as a results of fact some frequencies are reserved for government use, and employing them is against the regulation.

As a trucker, I spend the night at truckstops most of the time. A lot of them have wi-fi in the parking lot. They have equipment on the roof of the building that covers the whole parking lot, which can sometimes be as big as 5 or 6 acres.
They use equipment like this:

Answer 6

maybe you should try the idea that you have, it is the best yet the most effective way for you to discover if it is possible or not. but if the signal cant pass through the building, try bouncing your signal to the other building on the signal path.
