Default WiFi outdoor coverage issue

Hi folks,

I am not a wifi guru but have a decent knowledge of computer networks (LAN & WLAN). I live in a place where access to the internet is still little expensive thoug I have an Internet (DSL) at home and office.

But the people those who don't have it and live near by my home keep asking me to share my wifi with them and they will pay there half. In the beginning I weren't comfortable with their request but my other close friends encourages me to do it as they are doing the same. Now I'm sharing my wifi with 3 other people.

Couple of weeks before I came up with an idea of "why not to share my wifi with more people of the block and other surrounded blocks". For this purpose I scanned my neighborhood for my wifi signal but the results are not satisfactory and the coverage of my wifi is around 30-40 meters only.

Anyhow it's not the end of the story but beginning. I search the Internet for outdoor solutions and how to boost the signal and bla bla. after some research I bought:

1. TP-Link outdoor 15dbi 2.4Ghz omnidirectional antenna
2. N connecter pigtail
3. TP-Link Acces Point 54mbps high gain (recommend by the TP-Link)
4. TP-Link Coxal cable 12 meter

Note: I live in an urban area and my target to cover 300 - 500 meters.

After installing this stuff high enough on rooftop of my home I am only be able to get wifi signal around 50-70 meters only and also unstable mean sometimes signal strength high/low/gone...

After struggling a lot I doubted it might possible that my AP is not powerful for the antenna and bought Cisco AP WAP200 to give a try but without any luck signal coverage is only limited to my home.

Do you guys have any clue what I'm missing?

Any help would be appreciated.


Thanks,

4ukh

There are so many things wrong here......SO MANY THINGS.

First...WISPs operators are loath to tell people how to share out their internet connection, because that's how we make money - by selling individual internet accounts.

Second...It will certainly violate your residential TOS about sharing your connection. Business grade may be a little more flexible, but internet providers are even prohibiting that now.

Third...You as the account holder will be responsible for anything that happens. Do you want a multi-million dollar copyright lawsuit or the FBI seizing your computers for kiddy **** - that one of your neighbors was downloading?

Fourth...An omni antenna more than 15 feet in the air overshoots close in street level clients. That's was municipal wireless deployments are no higher than light poles.

Fifth...Laptops and smartphones are very weak and won't be able to connec back to you.

It will very likely work up to 500 feet.
It might work past 500 feet, or it might not.
It might work up to 1,500 feet, or it might not.
It will very unlikely work past 1,500 feet.

This is all assuming you have a clear line of sight (no trees or buildings in the way), and outdoors. If indoors, you will be very lucky to get 500 feet.


Example - Where customer is outside, like in a park, and you can see the AP with nothing in the way.

Less than 100 feet, you will have have good signal.
From 100 feet to 500 feet, you will very likely have good signal.
From 500 feet to 1,000 feet, you will likely have good signal.
From 1,000 feet to 1,500 feet, you might have good signal.
Over 1,500 feet and it will *likely not work*.

If there are trees in the way, you may get one half of the above distances.
If there is a building in the way, you may get one tenth of the above distances.
If you are inside, you may get one tenth of the above distances.
If you have a smartphone, you may get one half of the above distances.

Sixth...As an internet provider, you would have to file your FCC/FBI compliance statement and semi-annual FCC service reports.

Seventh...As your clients are standard 802.11b/g radios, a single AP will start to choke past 30 to 35 actively connected users - the "hidden node" contention barrier.


Bottom line...Let your neighbors get their own internet connection.

Desperate to see it working and effective results are mutually exclusive.

Sorry, but this spells failure from the start.
