bandwidth dimensioning

["Eduardo Gargiulo" <ejg-debian@wifi.hn.org>]

Hi all,

this is my first message to this list. I would like to know if there is a
formula or method to calculate the minimal bandwidth requirements for a given
network. I'm thinking to pay a data link to feed a debian box and from there,
via wireless links (802.11b), give internet access to aprox. 15 users. I want
to guarantee 128 kb/s for every node. Which is the best way to calculate this?

Any hint would be appreciated.

Thanks in advance, and sorry for my english (i'm from Argentina).
