Long range wireless.

[marivize]

I need to get a long range adapter to get optic fiber from my grandparents cause it can't get to my house.
It's about 0.67km, x miles
I'm thinking about getting two CPE510, but I don't know much about this subject, and IDK if I only need these 510's.

Thanks!

is these a straight line of sight between both houses?

you might be able to get signal if you use a high power directional antenna

but it definitely not going to be close to the speeds at your grandparents house

if you like overkill

This antenna supports only 470 to 700 MHz

The antennas you found are not bad actually, but lets do some math:

- I suspect you have a direct line of sight, no reflection, no shadowing

 

The path lost can be calculated with - 20 * log(wavelength / (4 * pi * distance)) = -20 * log(0.06 / (4 * pi * 670)) = 103 dB dB

 

The allowed transmitting power of WLAN is around 100 mW (Switzerland law!!!) -> 20 dBm (I know the antenna can do up to 27 dBm, but check the low in your area.)

A receiver can work at the lowest data rate with minimum signal strength of - 95 dBm

 

So path lost allowed: 20 - (-95) = 115 dB

Path lost required: 103 dBm

-> you are going to make it with a speed of 6 - 24 Mbps, IF:

- you have a direct line of sight

- you have no nearby network on the same channel

- your antennas are positioned high enough: multiply the height of the both antennas > 20 m ( to avoid reflection)

- you have additional attenuation like rain, trees...

 

When you are lucky you may reach a 36 Mbps connection, but you will not benefit from the fiber connection!

 

By the way I'm studiing this topic^^

[Stefan1024]

Lower frequency will lower the path loss, but with a 2.4 GHz system you have only 7 dB more receiving power. And you can't lower it more because of the data rate.

No way, sorry!

Thanks to everyone who posted in this topic!
Do I need any router or something like it?

Can someone recomend any?
in portugal you can get all the power u want I guess.

if it aint powerfull enough I'll get something like a 2424B  ...

[marivize]

By the way:
There are a few (lots) of trees.

It's a 30Mpbs network.

I also have my uncle's place with the same network, but with a hill covering everything up...

[Blebekblebek]

unfortunately you probably won't get that speed

back when I use that antenna the range was 2km

I'm using it just for internet accessibility (and it was very slow, kinda 5-15mbps max)

 

you need both antenna to broadcast and receive

and my device was internal access point converted with poe, and the broadcast router also using poe it just WRT54GL.

 

well I'm not dealing with this stuff again, since nowdays internet are common, actually I need lot of stuff back then

tower, lighting protection, ups, pipe for cable,coax cable etc,... it's a lot of work, but you might just do well with setup like regular antenna on roof.

[Stefan1024]

Only 30 Mbps on fiber? OK, I was expecting something like 100 Mbps...

 

The 2424B is only an antenna therefor you need also a good low noice RF amplifier. The CPE510 has everything you need on bard.

 

A hill can easely cause 20 - 30 dB of attenuation ( you only have a margin of ~10 dB). Trees are not that bad.

 

Literally every second or first world country has some limitations on transmitted power. And remember 20 dBm = 100 mW, 27 dBm = 500 mW. But as long as you don't overpower your neighbours network you may get away with it.

 

Without extem detailed information about the area I yan only make some approximation. It's no a garantie you will make it. And your margin is quite small. If there is an option to use your "normal" internet connection. This migth be also cheaper.

I don't know much about the CPE510s but a pair of Ubiquiti NSM5s (https://www.ubnt.com/airmax/nanostationm/) should do the job and wouldn't be that much more expensive. UBNT even have the AirLink calculator (http://airlink.ubnt.com/) which will give you a rough idea as to whether it would actually work due to obstructions and relief.

[marivize]

Actually a friend of mine used 2 NSM5s and then trade them to the CPE510, dkw, but I would prefer the 510's

I actually need kind of a How to, so that I can setup this...

Do I need another router for me, or just the emissor needs one?

It works more or less like a long ethernet cabel when you cunfigure it as a point to point connection. You don't need another router. But you may need a switch / hub when you don't have a free port on your router.

 

There is a lot of documentation on the TP-LINK webside. Just read the quick installation guide (before you buy it).

if you cant see the house you are connecting too wireless i would recomend some of these also using wireless that far can be degraded when it rains and could lose connection

and plot out a route along fences

 

also using wireless that far can be degraded when it rains and could lose connection

it could be a sad rainy day

[mineblaster]

and probally find somthing suitable but all i can find in 5min
