designing wireless network

[feline78]

hi all, i am newbie with wireless and i need to design a wireless network that shall act as a backup to the wired network in a building.

the building has 10 floors.my opinion is that a 1200 (g standard) AP on each floor is suffice with a radius server for central management of the clients.

am i correct or do i need to take something else in consideration. your opinions will be appreciated.

thanks in advance

You need to consider both coverage and bandwidth when deploying wireless- i.e. can you get signal at all desired locations, and how many users will be sharing a channel?

If your floors are relatively small and you will have relatively few users, your solution may work well. But, you can never be certain you'll have coverage until you actually put an access point into place and walk around with a client to make sure.

Bandwidth is a separate issue. If you're deploying this as a backup to a wired network, then that means that when your wired infrastructure breaks, all your users will be hitting the wireless. You don't want more than 20-30 users on a single access point, depending on their usage needs; how many people will you have per floor, and is one AP adequate to handle that load?
