802.11b Wireless ISP CPE: How To Build?

Need Info On 802.11b Wireless Isp Equipment

I work with a wireless ISP in Lagos, and I have been assigned some R & D task: finding out modalities of a cheaper Customer premise equipment.

At present we use the airBridge TOTAL from smartbridges.com, but it costs $300 (approx. 44,000 after shipping).

Is it possible to build your own, using antenna, cable, pigtail and PCI card? I know some ISP's use a similar setup.

If you get this message, then you are very lucky to be among those saving and accumulating cash for themselves in 2009. Money you would also use to have a wonderful time this festive season, is being wasted away in the hands of greedy cyber café owners and internet service providers that charge you a fortune just to browse the internet. Come to think of it, if you are a regular cyber café visitor like I was, spending a minimum of two hours daily for seven days, then I would advice you to sit down, take a pen, and make a simple calculation of your monthly expenses in the café, surely you will be alarmed at the result. Same with you who is using the private or home internet connection because we are all victims of the same exploit. But that ends today! because a new revolution has come to stay in Nigeria "TOTAL FREE BROWSING". It's a pity many people still don't believe that free browsing exist in Nigeria, but I can tell you that this message you are reading is sent to you using my laptop, configured with the free browsing softwares and settings. No regrets for the money spent in cafes and with home service providers because you won't be spending a dime anymore to browse the internet. Presently I have configured over 20 laptops and phones to browse for free and the beneficiaries still see me on the road and shower big smiles of "thank you" on me. To be among the big smilers, call today to order for a package of the connection settings to configure your laptop or desktop to use the free browsing for life. Order before Jan. 10th and get the configuration settings to browse free with your phone free of charge.

Hello Chrisblack, as for Realtek, I have used some of their items and i feel they are good and strong, but you will have to consider distances and climate, They come out with Chipset 8186, which we have hacked here in philippines and can reach a power of 4watts, thats roughly more than 30dbm,

I can make a link for you, Please email me  bimbo@abimbolaadewoyin.com

I run a wisp in a rural area here in Philippines and i have also installed a link in Ibadan in a rural area, i normally use realtek CPE, depending on budget of clients and Wireless Radios like motorola Canopy, Mikrotik , Cisco. we can setup something cheap for you and affordable,

please email me and give you list,

bimbo@abimbolaadewoyin.com

Hello Gridlock,

Are you only looking for CPE solutions or APs as well. I am manage and partly own an ISP in Nigeria. We are currently using CPE solutions with antennas, site survey and installation fee to the client at N50k. If you're interested, I could probably work out a good deal for you in whatever quantity you require.

Let me know if you're interested,

Okay, i am narrowing down my search. I think i can get a pigtail and LMR cable here. Main problem is antenna and PCI cards.

Does anybody know where i can buy parabolic grid antennas or yagi antennas (minimum of 14 dBi) in nigeria? I have a payment and shipping problem with outside countries (they always say we dont ship to nigeria, anybody wonder why!). I aslo need wireless PCI cards, like, somewhere i get to buy in bulk.

Thanks.

[building the CPE myself gives me more flexibility: my mini-accees point has been up for 2 days, no hitches, and i can switch channels, auth-mode and tx speed (a, b or g) without rebooting. when it was running on dlink's firmware, i couldnt do that]

I seriously advise against using amplifiers. This is the problem every ISP is facing presently. When you amplify, you kill everyone as well as yourself. Remember amplifiers do not only increase signal but also increase your noise. Stick to Sector antennas with whatever radio you use and your CPE units and try and balance out your channels. DO NOT, I advise, use amplifiers unless you are causing more harm than good for yourself and others.

Like I stated earlier, if you contact me offlist, I will probably have a solution for you to do the job you are looking for.

Hi Gridlock, The cost of your CPE will be determined by the wattage of radio and the antenna gain you intend to use.

Your best bet is to have enough gain at your base station so that you can have less power requirement at the CPE end. Use sectorial antenna and a powerful radio in the range of 1 to 2 watts, you can achieve this using amplifiers.

With the above, a 65mwatts and 14dBi antenna will go as far as 3km while a 200mwatts of the same configuration. Note also that some modern antennas comes with pouches which houses your radio and allows you to make it outdoor. That saves you the cost of IF cables.

If you care, I can provide you with 65mwatts CPE radios(ethenret radios with POE support) of the above configuration for only N40,000.00 and 200mwatts with 14dBi for N50,000.00

I am assuming all the way that you are operating in an ISM permitted environment and not acting illegally against NCC standards.

hi Gridlock,

If the base station unit support PCI Card, "that's nice" but the distance it will connect at 500ft is another issue, but i can give you a suggestion on weather you can extend the coverage area with a pci card, You will do more of the work, go internet and make a researche on verious kind of ant that can work with Pci card, i guess you will find one btw 12 and 19dbi you wanted, the manual of that ant will instruct you on how to make the connection but to be precise what you will do is to remove the small ant that comes with the wireless PCi card and insect the one of the ant, with this you will be able to design a cost effective CPE but i dont no how far your base station unit signal can go, that will determin how far your CPE can be situated.

You are right by saying wireless g card cannot go far but they work effectivily than B card, the reason why hunter i advice G card is for futuer purpose and when there is more request on bandwith from your customers and large data is required to pass through,

Gridlock, let me put a tip in your mind now, if you are not consdering Wimax systems now, dont think your system can go far as 12km radius (you are assuming theoritiacally), in achieving 12km or more, try considering about 4 sectorial ant backing themself so that you can achieve feather distance just like the way the telecom guys does, check any terminal station of any telecom company, they dont use an omi directional ant but sectorial cos the secotrial look at one end and go farther than omni, If only your base station unit can go farther for about 12km radius or more with an omi ant then go for it but follow the directive of your base station unit vendor.

Before finalizing on your decision let your company setup a test wireless network and conduct a proper survying in testing the solution from your base station to about 12km radius or more if you use the right CPE trying to connect.

Thoeritically it should be possible, but wether you can do it for cheaper (and better) than a purpose built unit, is somewhat doubtful.

Hunter is right!

i also advice using G-class instead of B, the cost difference is not that much! very soon wireless vendor will stop production of wireless B b'cos of the invent of Wimax promising about 25miles coverage capabilities, by this time next year, Wireless B will no where to be find if you dont deploy G-class. So look into your consideration. when Wimax system will be much in the market or very popular, it might be diffilcult for wireless B client to connect or wimax systems might not supprt it b'cos of it's limited data rate transfer of 11mbps. you can imagine a base station in a distance of 20miles away and you want to use wireless B client to connect and B data rate speed is 11mbps and again now where voice, video and large data are going to send throught wireless media, so you can see how the connection is going to be poor or it will never work at all compare to G where you have total connection thruoghtput from 54-108mbps. another consideration is the security perspective of it,

one advantage I can see is that you could potentially get a speed and security (limited security) by using a directional arial in your CPE.

Also wouldn't you be better to deploy 802.11g, it's cost isn't exactly high and you've got backwards compatability anyway.

In building your on CPE, there lots of option you will have to consider. If you talk about using a Pci card with ant and some other devices, you will ask yourself if your base station system will support that i no of one system that allow the CPE to be either a brigde or a wireless PCI card, A friend of mine that work with an internet wireless provider like yourself use a system of a very simple brigde that is not that cost but built it in a kind of way that suit much like a CPE. i don't have the picture of one here i would have show here. the one you said your company use which am seeing here, !! too big, or probally it work fine,
