1200 acees point

[feline78]

as per my previous post, i am designing a wireless lan for a ten floor building, each floor has an area of 530 sq m, i am presuming that a 1200 access point is suffice for two floors. the total no. users for all the ten floors is 300 hence i am taking an average of 30 users per floor. anybody can advice me if i am thinking right about the ap's?

My opinion: NO. One 1200 for two floors probably won't be enough.

The long(er) answer: "It depends." Building composition (wood, brick, steel, drywall, etc.), type of antenna, type of client (and the client's antenna), other potentially interfering signals .... and many other factors all add in to the mix.

The only way to be sure is to do a site survey and map it all out.

At work, I have an AP1200 that covers nearly the entire floor (~200 ft square box with elevator lobby in the center) for clients with the Cisco a/b/g NIC .... but doesn't even cover 1/4 of that for clients trying to use laptops with built-in / internal NICs.

Without a good site survey, any specific answer (good or bad) is pure speculation.

What it boils down to is: "Are you willing to put your butt on the line for a "good guess?" (or worse ... a good guess by someone that has never seen your location?)

FWIW, from the systems I've done .... No, I don't believe it'll work according to the design presented.

Good Luck,

Scott

thanks that was surely helpful

however i have one more thing to ask, if we deploy an access point on each of the ten floors, how to do the channel settings (considering that we use 802.11g standard) since we have only 1,6,11 channels that do not interfere.

the answer still is it depends. If there is false ceiling u might not be able to communicate between floors so u can have channel 1 to one floor , chanel 6 to 2nd floor ,channel 11 to 3 floor and again hanel 1 to floor 4 and so on. generally i have seen that buildings with wide open areas and without false ceiling let the signal upto three floors , otherwise not still u can go by this method.
