    Question Extending Wi-Fi by 800m to Sports Hut

    Hi

    Currently running a staff wi-fi network using 50 x Buffalo routers running DD-WRT which gives 100% site coverage and a smaller student wi-fi network on a different VLan.

    The PE department are now asking if it's possible to extend the staff wi-fi to the sports fields which is about 800m away as the crow flies. It's mostly fields between the two and if you stand on tiptoes on the roof of the main site you can see the hut so a fairly good line of sight.

    What do the fellow geeks of this fine forum suggest as the cheapest way of extending the wi-fi that far? The hut is secure and has it's own electric supply so no issues with putting in a cabinet or leaving equipment powered on. All they want to do is run a RDP connection back to do the registers either on their ipads or netbooks.

    Any ideas gratefully recieved
    Thanks
    Andrew

    Use a simple powerline adapter connect it to a port on the switch and connect the other side into the sports area then the one from the sports area could have a wireless array connected to the other powerline adapter?

    Obviously as long as the Sports hall shares it's electric with the main building and isn't on a separate electrical circuit!

    Hi

    Sadly, totally separate supplies.

    I'd say your "best" option is to get a fibre cable run between the 2 buildings. I'd guess that the landowners between the buildings wouldn't put up a huge fight to having such a cable buried along hedgelines or similar.

    However, that will not be the cheapest.

    Other than that, you're looking at point to point wireless, which would require something like this - Liberator-V320 | 60GHz Point to Point Wireless Ethernet Bridge | Sub10 Systems.

    Every installation is different though, so you'd probably be best speaking to a network specialist like @Net-Ctrl.

    Xirrus arrays may be of use here, as they have a massive range on them (and can handle a large amount of users). If I remember there is an xirrus account on here who could help.

    Failing that, you could also look at wireless repeaters.

    Neither an ordinary wireless 'repeater' or a Xirrus array would be any use as far as I can tell, as you're talking about nearly 1km distance.

    Best 'small' units I've seen are Unifi devices which will work over 600ft outdoors.

    I have used Xirrus arrays before and yes they're very good but don't think they will reach up to 800 meters away and are very expensive bits of kit (rightly so!) To have that many wireless repeaters he'd need a socket every 50 meters to plug one in and the connection would be so unstable he wouldn't be able to use it. @AJWhite1970 If they're on separate circuits fibre might be your only option as any other cable that length such as Ethernet you would loose too much power and wouldn't work properly I completely agree with localzuk!! Hope this helps mate!

    You could speak to someone like 4gon about point to point wireless if there is line of site. Point to Point Wireless - 4Gon Solutions

    Hi Andrew,

    Are you looking to provide wireless access across 800m stretch or to an areas that is ~800m from a building?

    If it is to provide coverage locally to an area 800m from the building then an option (using mostly existing kit) is to use directional antennas and create a MESH (WDS) link between two APs.

    There are mainly out of the box solutions that would do the job nicely too. Ruckus have a PtP solution, the 7731, that comes as a pair. Its a transparent layer two bridge. One AP at each location.

    Hmmm I don't know. I've never heard of this company myself either and if you don't use them then their "up too 15km" wouldn't satisfy me I've also never heard of the manufacturer :/ but that's just me!

    The manufactuer is well known, the company is a reseller.

    Ubiquiti are the ones that make Unifi that people use, I think they started off doing point to point wifi though.

    They're relatively new (in the education arena at least), but there's a pile of people on here who swear by Ubiquiti's equipment. Supposed to be very good, and very cheap for what it does.

    As much as I love Ruckus gear, the 7731 is very expensive from what I've looked at.
