Effects/distance on wireless connections?

I just recently asked about connecting two computers to the cable high speed internet. I wondered whether the wireless would have troubles travelling the distance. The computer downstairs sits at one end of the house. We built an addition onto the other end of the house. So, the wireless connection would have to travel 45 feet across and 15 feet up. Will this be able to be done? It seems the wireless would have to travel through the roof into my room upstairs. It seems like a lot, but I don't know. Help!

    Hey Dude,

    Wireless distance and signal strength is sort of a black art. Not many people really understand how it all works, and for those of us who do, well, we are a bit strange.

    MANY things affect signal strength and distance. Concrete, wood, people, and believe it or not, metal screens (like screen doors.)

    The best way to see if it is going to work is to DO IT. Install the wireless access point and see if it works. Do a site survey; walking around from room to room and see how it performs.

    Now, do not forget we have 3 variables. 1. the environment. 2. The wireless access point. and 3. The wireless device(s) itself.

    Different wireless devices have different signal strength as outlined by the FCC regulations. A Dell Axiom is different than a laptop in signal strength.

    Hope this helps a little.

    I see no reason why it shouldn't work. I have a wireless network and I can detect 3 different networks from the surrounding houses. With one being 4 houses away. If you do have a slight trouble you can buy a cable to extend your aerial out or buy another aerial which comes with a base and about 2 feet of cable for about $30 to $50 from your computer store.

    If you use pre-n (or 802.11n) wireless hardware then it should work just fine. If you can't afford that, use 802.11b or g, as it does better with corners and places where you don't have line-of sight. 802.11a has a long range, but doesn't work very well when you don't have line-of-sight. One more consideration is what type of phones you use in your household. If you have coordless phones, there probably will be a spectrum identifier (such as 900mHz Technology!) on it somewhere. If you use 802.11 a, or b/g, then make sure you use one that is not in the same spectrum band as your phone. 802.11a uses the 5GHz band, 802.11b uses the 2.4GHz band. If you have 900mHz band phones, this is not a problem. Also, if you use 802.11n, then you don't have to worry about the phones interfering.

    A lot depends on the make and model of your transmitter, and what type of building material your home is made of.

    As an example, my neighbor that lives some 600 ft. away, has a wireless that I can use upstairs but not in the basement.

    Most units are ultra high frequencies (UHF) and are basically line of sight.

    You will never know until you buy and install it. Keep your receipt and if it doesn't work, make sure you can return it!

    what type of wireless is it. B/G/N if B then it might not travel that far. I have G w/SPeed boost with regular antenna I get about 150-200 ft from the house to the workshop. I installed it to a outside omni directional TV antenna and I have picked it up my signal with 2 bars out of 6bars strength @ around 4000ft with that. Of course I have it encrypted so no one can use it but who I want to..Thanks

    Forty-five feet isn't that far. However, you would have to pass the signal through the ceiling. You can defeat that with a signal booster. What you really need to do most is locate the router upstars. It is easier to get the signal down than it is up. The next thing you can do is get signal boosting antennas. They cost about 30 bucks. Good luck.

    45 feet should be okay but since the signal Will have to travel through walls you might want to get a high gain antenna. that should boost the signal far enough to get a good reception.

    Hope this helps!!!

    Its possible if you buy high quality equipment. I cant recommend a specific brand to you, but I would look for a brand that sells range extenders and possibly high gain antennas. It may be easier, however, to run a cable in a discreet area.
