wireless distances & recommendation

Postby dve83 » Sun Sep 26, 2004 6:46 am

hey everyone,

1) what is the longest distance any of you've reached with Wireless networking (that is: with standard out-of-the-box and non-modified hardware)?

2) is this any good? anything else to recommend.

note: looking for distance with acceptable transfer rate (not the fastest). will be between 2 buildings.

thanks a mil

The effective distance between two buildings is highly dependent on the building construction. For example if the outside walls are steel reinforced concrete vs. wood frame, I would expect significantly higher performance in the wood frame situation with identical equipment.

With my SMC "g" technology I can recieve signals in my car and connect to the router located inside my home at distances around 1,000 feet. Someone else in my neighborhood has an unsecured router that I can use pretty much at will ... don't know how far away it is. I suspect it is a Linksys product.

Usually, the wireless router comes with additional signal boost which can be purchase optionally, which in your case will help you.

The best cards out there with the longest range are made by a company called Senoa, with the next in line being SMC. They have model's branded "High Power" which have exceptional range.

You'll have to descibe the "two buildings" you are reffering to.
If you are taking about 2 houses side by side, then commerically available equipement at Staples or some place like that would be ok, but if you mean two office buildings, you are going to need some directional antenna's and other heavy duty equipement.

hi,

the two buildings are about 100-120m. Unfortunately weve got stuff inbetween. This would be a field of about 30m less than the full distance. And we have a few trees in the way.

Another thing: i heard about senoa. but apparently there is a international legal limit in signal strength. Correct me if im wrong. It should be something less than 120mW if im right, and a guy from one of our local suppliers told me that some of these long range thingys have a rating of about 220mW.

true?

me and a buddy are just looking to try out wireless. obviously if it starts getting way to expensive, it wont be worth it. Also we want to stay within legal boundries as far as we can help it.

With that kind of distance, you are looking at purchasing some directional equipement to help transmit the signal.

Stuff like this.

I am not sure of the legal limit of those products - I am sure its different depending on your state, I just know they have the best strength on the market.

Or else playing with some old satelite dishes, heard something about that, from a workmate, will see if I can get some URLs for you.

Ive got wireless from downstairs, and it has to go through several walls, even main ones with the steel beams through them, to get to me. best thing is to try and see if it works, its not like your wasting money on cabling

You can make antenna's out of cardboard and stuff like the Cantenna. But in an office type community, you can't be fooling around with toys. You need stuff that just works.
