how to design a wireless network.where 2000 km and 200 network nodes. any one know answer or from where i can?

Check the wireless networking forum at dslreports.com.  Also, rephrase your question so that it makes more sense.   What do you mean by 2000 km and 200 nodes?  Do you mean each node needs to have a range of 2000 km?

A typical router can handle about 128 computer or other device connections.  \n\nI would not worry about attenna parameters, unless you are a total geek.   But then you would have done a search at google and learned already. \n\nIf one of your computers has a low signal strength, then look for solid obstructions.  Brick walls, chimneys and other solid stone or brick wil STOP the signal cold.  It needs straight Line Of Sight to work well.    Also, a cheap cordless phone can interfere with the signal.\n\nGood luck and Happy Computing!

first u have to build a LAN with 20 systems using a switch/hub then conect both the rooms network with the centralized server.

If you are talking about a home network or lan just buy the wireless equipment. In the longrun it will cost less than a wired network and you wont have all that wire running everywhere.

Standards.  Actually, there is a 802 standard (100BaseT4) that uses all eight wires, but it's not commonly found.

Check out this site here It gives step by step directions. He says it will give you a 3-5km range. That should give you roughly 1.5 miles or so.\n\nhttp://www.usbwifi.orcon.net.nz/\n\nBy the way it isn't omnidirectional, so you have to have a pretty good line of sight between antenna 1 and antenna 2.

buy a satellite dish and a linksys router and go online and find the directions, and build it.. it had a range of .5 miles wifi

When I do a design I use the three basic things to define a network. Physical connections, logical (ie network routing and switching, IP address schemes, etc...) and finally application information (usually I use tcp ports to define what is where since quite a few customers do not have a list of running apps). Once you have that information,  start from what you would consider your data center. Define it as above and start working your way out. Wireless presents an inetersting problem if the system is not strictly point to point. I typically use Visio to do my work in and then save it to pdf since alot of folks do not have visio as a viewer. Hope this helps, TX

By using Google.\n\nhttp://www.google.com\n\nSearch for WiMax and also 802.11.N

Setup up a network where all your electronic equipments are connected to one central hub. It is kind of tough, but it sure will be one hell of a project.

Depends on where you live, if its a densly populated high tech area i.e. Downtown with highrises, all you need is a USB WLAN Network Adpter b/g, preferably with a speed booster.\n\nI have a limit on how much stuff I can download a month...so sometimes I borrow extra bandwidth from the neighbours that way :)\n\nOf course no one can guarantee the presense of "AN OPEN WIRELESS NETWORK" but the better wireless adapter you have, the more chances u get to work with.\n\nNow you can go even further, and invest into a "Yagi" directional antenna (which will cost you ~200$) But you can get the same results with a "Pringles can" and 10$ worth of supplies from RadioShack. With Yagi antenna you can pick up further wireless "hotspots" with good signal amplification, and almost no interference - due to the directional aiming.\nWith Yagi's you can sometimes pick up networks 1.5-2 km away from you - compared to conventional 500feet (166 meters)

You may just need to look into some really good UHF amps, and some form of filter to narrow the input range to the part of 2.4ghz consisting of Wi-Fi. \nYou also have to be careful about other electronics that share the band. Bluetooth is right next to 802.11B/G, and I think cordless 2.4ghz phones share that side as well. Microwaves also emit some radiation at 2.45, which is also right next door to wi-fi.\nI have never seen a schematic for the Wi-Fi hotspot finder online, and I think the most obvious reason being the relative complexity, and the fact that you can get it for $20 like the other guy said.\nIf you're determined you can make it work. You need that UHF amp and filter/tuner.

Setting up a home network??\nYou are rather vague perhaps a little more info might get you what you need.\n=)

Don't forget, wireless is a shared medium.  Like a hub.  If you're running two clients full speed to a single access point, each can only use half the rated bandwidth.\n\nAnd just having a second host turned on could be throwing out packets (NetBIOS discovery, virus updates, any amount of chatty traffic spewing out of the modern laptop) that are slowing down the other device.\n\nAlso note that because 125 isn't a part of the real spec, any number of oddball things could be happening behind the scenes.
