set wireless in office building.

hello, i need to setup wireless in an office building with 4 floors. it
comes from one internet connection. my plan is to use one access point
with a bunch of repeaters(range extenders?). its there a better way to do
it?

Yes, get a switch and run ethernet to some APs on each floor.

If feasible to run cat5 wires to the other floors, look at a wap router on
the first floor, with a hardwire going to each other floor (WAP Routers have
4 hardwire outputs), and the wap's on the other floors having the same
ssid/channel, so the users can go between floors and stay connected.

its going to be really tough on my end to run any wires through other
floors. what's the purpose of having waps on every floor instead of
having a range extender on every floor? can/does range extender run in
series? something like wap on first floor, then range extender on 2nd
floor feeds range extender on 3rd floor and so forth?

No sympathy. Do you have telco conduit running between floors to a
common phone room? Every office building built to code since the
stone age has such an arrangement. Run CAT5. If that's also
offensive, I've successfully used *TWISTED* telco wire (25 pair) for
ethernet. Use the existing phone wiring.

You'll see a reduction in available wireless bandwidth. A store and
forward repeater, range-extender, distance stretcher, WDS bridge,
packet regurgitator, or whatever can only transmit and receive one at
a time. This effectively cuts your available bandwidth in half every
time you repeat the signal. One access pont and 3 repeaters will cut
your bandwith by a factor of eight.

Yes. Watch out for chipset mixes as it's considered a good idea to
have all your devices run the same chipset.

By the time you get to the 4th floor, you'll have 1/8th the available
bandwidth left. For example, if you have a 1.5Mbit/sec DSL connection
available at the initial access point, 3 repeaters later will show
166kbits/sec.

Run the CAT5 cables and forget about repeaters.

To roam, do u have to use the same channel?

With repeaters, EVERYTHING is on one channel.
With multiple access points, they can be on different channels.

The access point determines the channel in use. If the client loses
the connection, it will start to scan all the channels looking for the
same SSID. If it finds the proper SSID, it stops on that channel. It
can be any channel, but the SSID (and WEP/WPA crypt key) must be the
same for the system. Multiple channels works fine for multiple access
points.

The repeater configuration must be on the same channel and have the
same SSID as the sole access point. Since the single radio is
half-duplex, it can only transmit on the same channel that it receives
on. Similarly, it can only deal with one SSID at a time, which must
be the SSID of originating access point. This effectively puts the
entire system on one channel.

Note that the client configuration does NOT ask for the channel number
in infrastructure mode. That means that it will connect to the SSID
on any channel that it finds an access point with that SSID. However,
in ad-hoc mode, the channel must be specified by the client.
