Can I Set Up A Canopy For Adsl For 2Km ?

[haveaniceday]

So 3BB say, no, will not run a line, TOT say it may work but not well.

Has anyone done or know how to do in Thailand to have a decicated personal 'beam" of ADSL between your place and near a box?

What I mean is to ave 3B plumbed into a friends place, that is connected to a line of sight set up to my place up to 2km away?

Any Ideas?

[surayu]

if it's in your line of sights as you wrote, have you thought about a wi-fi/radio link?

[haveaniceday]

I know nothing about the subject, well enough to know I know nothing might be the more correct way of saying things, after further reading, it looks like "canopy" may refer to a Motorola product, point tot multi point upload and download, commercial system, I have every reason to believe I can make it line of sight, up to 2km.

Please tell more about wi-fi/ radio link please?

Rough cost and is it effected by rain if you can be so kind please ?

[surayu]

Have a look here, they sell stuff like this in Bangkok too (Pantip).

2KM is definitely not too far for a ADSL line. Heck, I'm a little over 2KM from the TOT central station/DSLAM bank and my TOT 6Mb package works fine/very reliable with very good Signal to Noise and Attenuation values...and I get full sync speed. At a 2KM distance you should be able to go up to around 8Mb ADSL no problem. I can understand why a phone company like 3BB may not want to run a line due to cost, but I wonder why TOT said it wouldn't work too well if they were talking about the line...maybe that's just their way of saying they don't want to run a line either due to cost. Maybe there are not enough trees to hang the line on.

You can Google "Point-to-Point Wireless" to get a feel for the options. 2 km seems fine; I've heard of some installations of 5 km. Not sure what happens during rainy season though. Also this topic may have come up before here so a search might yield local experience, and equipment.

Come on guys the OP never tells us how far his friend is from the DSLAM, just that he is 2 KM from his friends place, maybe the reason TOT says " it may work but not well " is due to the fact that the additional 2 KM from the DSLAM may degrade the signal too much

I just wonder how much the egenius device that surayu posted would cost

Unfortunately i can't remember it, however i think it was something around 3.000 Bahts? not sure, maybe somebody going to Pantip can report back? One thing i can say it's that i have no complain to made since the purchasing, finally something that works!

Yeah, wireless can be done, but not with that antenna ^ above.

Not enough gain and the beam angle is too large

TP-Link has a wireless calculator page,

good enough to give perspective to the issue.

I used the following params...

Transmitter/Receiver TD-WR741ND (802.11n)

Antenna TL-ANT2424B (hi-gain and tight beam width)

Distance 2.5Km (a little xtra distance)

I'll just paste the contents of a text file I created a while back...

has the links and some info, check it out, play around.

Best of luck to the op...

Not enough gain and the beam angle is too large

According to the manufacturer it can reach up to 30km, the OP is talking of 2km....

[howto]

Apologies surayu, no offence intended.

Note that I did not suggest any particular antenna.

That engeniustech antenna will not be "usable"

in this application at that distance.

Perhaps it will reach out 30 Km,

but only give one perhaps 33kbs bandwidth,

and drop if a dog farts nearby.

Perhaps it would be ok at 500 meters.

Very likely they will have a unit that is ok.

I noted that TP-Link has a unit

that looks identical with the same specs.

Not surprising as they are all from China.

The calculator does allow one to see the

effects of using antennas with different specs.

Just pick a different antenna from the drop down.

The results will be very clear.

That was the purpose of my post.

For the money and effort,

I would prefer a rock solid, >54Mbs connection.

Cheers
