    Hey guys..

    Well.. basically i am looking to put wireless in a 6 story hotel/motel building..
    The building is probably... 20 x 20 meters... 6 stories high.. about 8 rooms per level..

    what would you suggest? what antennas... i read the new LinkSys wireless-N router is suppose to be good.. but id rather want some answers from people that know what they are talking about

    Any advice would be appreciated..

    Thanks

    okay this is what you do, you run a neutral z x-5 linksys router package from the base lobby to the upper maint. shaft, run glow sticks the whole way for easier travel, setup a wifi smart top 3000 in the elevator for increased speed on the shaft and then put dummy cameras in each room.. it will work perfect

    you can either buy a couple repeaters, or what i would do it buy a couple wireless routers for cheap. here' sthe schematic:

    modem -> router -ethernet cable-> wireless router -ethernet cable-> wireless router...etc

    for each wireless router you have to disable dchp. you just have to daisy chain the wireless routers and they should act as access points. downside is that you need to run cables up the building.

    It goes without saying that we'll need naked pictures of the women staying in your hotel in order to say for sure.

    But seriously, Rob is right.. we need more information about structure, layout, etc. :dunno:

    Haha.. Thanks guys.. really the walls are made from.. cement/bricks... and are approximatley 15cm thick..

    What i was thinking having the router in the office.. and doing a few antenna's? or would repeaters be a better bet?

    Linksys Routers running Sveasoft and WDS running on all of them.. That way they are all hooked together..

    This would be the worst option. 15cm of cement/brick would effectively kill a signal pretty quick. Also, you'd add so much attenuation from running an antenna cable 6 floors from the AP that it would be useless.

    My opinion, pick up a 24 or 36 port switch, buy 4 (linksys/whatever) access points, put the 4 on the same floor and see what kind of reception you get in each room (basically, mock it up). 60m x 60m with walls and shit is going to take at least 4 APs, maybe 5, but you'll never know until you try.

    Then, go one floor above and see what kind of reception you get there. It may be that you can skip a floor (put APs on floor 1, skip 2, put APs on floor 3, skip 4, etc) because the bleed through from the floors above and below may cover it.

    What I bet you'll find is you can get decent enough coverage if you put.......wait...

    Say your building is diamond shaped with corners at North, East, South, and West. You may be able to get away with putting APs at N/E/S on floor 1, then E/S/W on floor 2, then S/W/N on floor 3 (rotating around the "missing" AP from floor to floor). Again, signal bleed-through from floor to floor should cover the missing spot.

    In my opinion you're going to need a switch and at least (6 x 3 =) 18 access points, but you're probably going to end up needing (6 x 4=) 24 APs to cover the building.

    You can configure WDS if you want but you probably won't need to (link to what is and how do do it).

    Lastly, I'm not saying put the AP in the N corner. Put it in, away from the wall...think about the signal as being a 50' circle around the antenna and place them accordingly. If you put the AP against the wall then half the signal is going to end up outside the hotel, not helping you, while leaving a coverage hole in the middle of the floor.

    No....if the floors are concrete then they were probably poured in a metal pan. It's possible an AP may shoot through one but highly unlikely it'll go through two floors.

    If it won't go through one floor on the stock antennae... an antennae with more vertical attenuation would do the trick.

    vertical annuation wouldn't do anything........ it can't penetrate the steel pans used to make the floor. *If* it can get through one (somehow, that's why I said test it in my first post) then it definitely won't go through two. A "stronger" antenna won't matter.
