Apologies if this has been asked before.
I have just moved into a house with 'up to 2 mbps' service. My parents, who live about 5km away, have 100mbps cable. Can I get a wireless signal to their house using something like one of these building-building wireless kits? They state up to 80mbps over 15km.

Anyone tried one?
Thanks

Not sure I have the technical knowledge to build my own. Just wondered if these kits work for the consumer, i.e. on a house and not a 100m mast.

getting good line of sighed between them will be key so depending on the view your house has a mast may be required.

OK apart from the LOS and mast height are they easy to install? How do you line them up as by eye will not be possible? What height for the mast is suggested when the land is flat? I need to check about buildings and trees etc but if this thing needs a 10m mast, planning permission and neighbours are going to get in my way.
Thanks

Line of sight is the key, and some googling shows that for 30km you need a 17m high mast to get line of sight, so standard roof TV aerial pole if there is real line of sight should suffice.
As for aligning, careful use of compass and GPS Hence why there is the option of a install service with the kit too.

Can I suggest you look at Deliberant APC-5M-18-KIT. Range is quoted as up to 20km, and in my application up to 100Mbps was anticipated.

@MrSaffron So I would guess a standard roof aerial at about 10m from the ground would suffice barring obstacles such as buildings or trees? I guess if they are in the way I need to go higher  Thanks
@anonymous Any reason why you suggest a Deliberant APC-5M-18-KIT?
|

|

Primarily cost - I identified these for a project last year and they come in much less than the alternative model mentioned.

Great thanks. Sorry for the newb questions but I am really struggling to find much online about how to install these things. Happy to have a go myself and comfortable with networking etc. Just some tips and suggestions would be great as I am a little unsure about what I should be buying to bridge a 5km gap and then how to install it! Reading a few very simple and brief online reviews and they just say chuck it on top of the house and with trial and error get a signal. Much like installing a Sky TV dish.
So how do you install the antenna at source address? Does alignment have to be exact? etc etc.
Does anyone have anything?
Thanks

Are there any WT Licences required?
What about RFI, from the link and also from microwave cookers etc?
|
|
|

Think there is a £50 yearly license cost. Dont know about anything else. That's why I am searching for information.

MIcrowave ovens - 5GHz is well outside their band, and easy to spot if an issue locally, as would wipe out the 2.4GHz band. 2.4GHz is not a good band to use for long distance due to the amount of networks already using it

Yep was looking at the 5Ghz models only as its 5km away. Back to my other point, does anyone have any tips or suggestions of fitting these things? Can anyone recommend a company to help that doesn't cost the earth? Thanks

OK I have used the finder it just lists a description and doesnt give you a name or any contact details! Not much use I'm afraid. Thanks anyway. I can't believe there is so little information online about this stuff.
|

|

Well it works for me, giving names, description and website addresses. I suppose it depends where you are.

Ring these people.http://www.solwise.co.uk/networkingwireless-outdoor.htm
The Technical Help Line is very good and they stock all the kit. I have used them for a number of years for my village wifi system.
Line of sight is the key to it working
|
|
|
|
Great thanks will give them a buzz. What equipment did you use? Is yours just a mesh around the village? How do you connect to the net?
|
|
|

lol

I use the Engenius 2611. One, set as an AP, feeds a mast at my house and then the other houses have the same unit set as a Client, no need to use mesh.
Feed comes from a BT landline
Details on setting up here http://www.solwise.co.uk/video-eoc-2611p.html
Basically you mount one unit on the first house and run a long CAT cable down the wall then inside and plug into the router. You then do the same at the second house and plug the lead into your computer. Height isn't important but VISUAL line of sight between the units is essential. You point the units at one onother but alignment isn't critical.
I have run to 2km but Solwise will tell you if 5km is ok.

A mast may be needed for line of sight because the Earth is curved http://www.radiodata.co.uk/faqs/line-sight

Great thanks this is very useful. So alignment isn't exact (like a Sky TV dish for example)?. Just set up the Access Point at my in-laws and then a client at my house roughly pointing in the right direction? Trial and error with height I guess? These 2611s are not mini-dishes so how does it receive unless the alignment isn't exact? Sorry for the continual questions! Thanks

An aerial radiates in an arc not a straight line so alignment isn't critical. Height is more important due to the Fresnel zone.

Sat dishs are aimed at something that is a few metres across 24,000km away.
So a basic compass and a map with both houses on it, should be enough to align them, then a little tweaking to ensure best signal.
Sat needs a dish arrangement to concentrate signal as it is such a low level, over the 2 to 15km wireless kit is seeing bigger signal levels, so flat antenna can cope. If property already has a satellite dish up, then do check the local planning rules as if you exceed certain height limits you might need permission, not sure of exact rules.

Of course that makes sense. I have a few companies preparing some quotes, I suspect some of them will be very expensive. From this it seems so long as you are comfortable with the hardware, software and climbing on top of a house its a DIY job? I could get a TV aerial guy to mount the AP and I can do the rest.
Will it work with cable broadband - does it just need an ethernet connection?
|
|
|
|
Yes, just needs ethernet.
|
|
|
How do people rate the ease of installation? I have had one quote come in at approx £3000 which seems high based on the costs of the some of these 5Ghz APs. I am more than happy configuring hardware and software (worked in IT for over 20 years) its just the physical install I am concerned with. Thanks again for all your help so far.

According to the table in the link, you need 8m height for 5.8Ghz over 5Km so the TV mast should do it. What is line of sight like - can you actually see your parents' house, or is there some large obstruction like a hill in the way?
|
|
|
A digital camera with a good zoom and video mode on the end of an appropriate height stick and a blinking torch at night held out of upstairs window at other property would be a simple crude test of line of sight.
Not sure what neighbours would make of it.

I am wondering if planning permission is needed for it, especially as there may be local by laws stopping the erecting of large poles.
May need to phone the local planning department before buying anything.
|
|
|
|
I think planning depends on height. 8m might be pushing it, most houses are about 6m with a chimney. I guess most TV aerials are <1m, they don't need planning. A quick call to the local council would be best I guess.
|
|
|
|
I think you can add the heights of the 2 masts together, if both houses have a TV mast of course.
|
|
|
|
Not sure I know what you mean? Do you have to add all the masts together to get total height?
|
|
|
It's mentioned in the link I posted.
Note that the antenna height means the height of both the transmit and the receive antenna i.e. for a link distance of 20km both the transmit and receive antennas must be 22.5mtrs above ground level (at 5.8GHz). The two antennas do not have to be at the same height. As a rough guide, if the transmit antenna is at 16mtrs the receive antenna should be at about 29mtrs giving a total height of 45mtrs. Or maybe not

just re-purpose a couple of sky sat dishes, no one will ever know.

Anyone know what the difference is between the antennas that are dishes and the ones that are not? Much like this

and then this

Cool thanks chaps. I reckon I am going to give two of these a punt http://www.wifigear.co.uk/ubiquiti-airgrid-m5-airmax... 27dBi should give me the best chance with a few trees in the way.
|
|
|
Trees get wet, so might lose signal when raining

Agreed, trees are the biggest problem on my village system. One year everything fine, next year no signal and a tree has grown higher and is blocking.
|
|
|
|
Leaf Growth in the Spring may also block the signal.
All of those UHF/Centimetric band devices can encounter that sort of trouble.
To emphasise what others have mentioned, a CLEAR Line of Sight is required at all times, otherwise it may become the "Line of Sighed" posted earlier.

Hi,
My thoughts...
1) Go for 5.5GHz to 5.7GHz rather than 5.8GHz as then there is no need for the Ofcom licence
2) 5km is easy with line of sight and aliging units is also easy at that distance (just use a pair of binoculars to spot the other end, then point in that direction)
3) For ease of use, I would tend to suggest a couple of Ubiquiti units like these: http://www.wifi-stock.co.uk/details/ubiquiti_nanosta... Just set one up as AP and the other as Station/Client and make sure you select correct frequency band.
cheers
Peter
