Wireless network advice needed

My friends office is almost 1 KM away from his home (direct measurement from google map), The PTCL land line option is not available in his Office Area. currently using witribe but its very expensive and have a limit. He has a PTCL line in his home. so the idea is to get a broadband connection there and install some equipment for wifi network and get internet working in the office. I need your recommendation about what kind of hardware will require for it and how much will it cost? I dont know any thing about wireless equipment or network.

Hmm.! in this scenario a little expert and technical approach is required. First of all get an 'N router' with a Detachable antenna option. Buy a 12dbi or above range "omni antenna" costs around 2500-3000Rs. Place a pole, either wooden(bamboo) or steel pipe on your roof. The higher the better. To make it problem proof use POE. attach the antenna using a subtended WiFi wire to the router. You can use an AP(access point) on the receiving end to receive better signal strength. make sure higher the range of antenna higher is the penetration power. Another thing that go for 2.4ghz antenna! they are now readily available in computer shops(in Lahore).!

So the things required are:

1. Wireless N Router

2. Omni Antena 2.4 ghz

3. WiFi wire with POE

4. may be an access point.

so what brand should i go for and what will be the cost of this equipment.

Ah correction a bit.

1. Correct.

2. 12db or higher 2.4Ghz Omni Antenna.

3. WiFi extended wire. this doesn't work with POE.

4. Access point.

there are two methods

1. you place the antenna on the top of the pole and attach a WiFi extension wire till the router. This method is discouraged as it increases the line attenuation between the two devices and the signal penetration gets weaker.

2. You place the antenna on the top of the pole and place the router besides the antenna few feet away. Now to power the router you'll need the POE(Power Over Ethernet) injector and receiver. Wat it does is that it help you to power the router without using an extra power cord. And the router takes its power from the Ethernet cable which works as an Uplink for it.

So you've got both of the layouts and i prefer the 2nd one its more sturdy and neat.!

Tp-Link is cheap and has all of the above said products available. Its soo far giving gud performance too.

so that means its gonna work even in long ranges area.. as mentioned in 1st comment about 1Km...? what are th odds of getting signals strength week or getting frequent disconnections..

For such links I would recommed using http://www.ubnt.com/ products such as bullet M http://www.ubnt.com/bulletm although it will cost a bit more.

For better range use a 16db+ range antenna...i was looking for 24db omni antenna but couldn't find in local market....best is 24db antenna!

I don’t think 24db Omni even exist, such antenna are usually directional. Try so me yagis

@ennay

Above given solutions may work, but i assure you that its a headache even after successful installation.

So dont waste your energy and money.

No offence just an opinion.

^^if done with technical expertise it will surely work otherwise above post says it all. And yup yousaf465 is right 24db antenna doesn't exist as yet..but experience says that 12db or above covers a pretty gud distance...900m easily.!

BUT is it legal? I don't think such experimentation is allowed without PTA's approval or am I wrong?

^^for WiFi there aren't any restriction anywhere..every thing is legit in this matter. You're not transmitting WiMax its simple WiFi. If it was to be illegal then every coffee shop or internet hotspot needed to get license from PTA.

I doubt wifi will work over a kilometre. Just make do with witribe.

Wifi with the right hardware works over distance upto 300+ km. Why could require a license from PTA ?

I already have a tp-link Model No. TL-WR740N router, also my friend have a 8dbi usb modem with some cable, so i think we should first purchase just an 12dbi+ omni antena and give it a try if thing didnt work properly we will buy another antena for reception.

Instead of 12Dbi+ omni go for a 16dbi+ directional antenna, your application is a Point to Point non-LOS if I understood correctly.

This might be a good starting point http://www.radiolabs.com/Articles/wifi-antenna.html. Find something similar to this http://www.radiolabs.com/products/antennas/2.4gig/2.4-aluminum-parabolic.php.

ok so i have to buy a 16dbi, but what are the advantages of directional antenna over the omni one. also i have just noticed that there is a mobile tower and some high trees between the two buildings, would it be an issue?
