Question : Wireless Usage

Hi everyone,

I am doing a feasibility study for a company that wants to install full wireless in a building that houses 1500 people. I have chosen to go with ruckus wireless, but my questions becomes about dedicated bandwidth. I am thinking of running a 30 Meg fibre into the building (all we can afford), but then I was thinking if 80% if the people at that site are simultaneously connected and downloading, I was wondering if that would cripple the network by saturating the link.

If I wanted to acheive a minimum of 256 K download per connection? What kind of a pipe would I need for it, expecting that there could be 1300 simultaneous connections at one time? I did my calculations the 30 Meg pipe for a dedicated 256K connection is a max of 120 people. THis is FAR too short. Is there other technologies out there, other methodologies? For example, a way of shaping each users download like a bubble, so if one use is only using 100K, then 156K can be given to other connections? Kind of like the way VMware shares memory across different vm's when resources are stretched?

Answer : Wireless Usage

Actually, if you want to provide 256K'Bytes'ps speed for each connection on a 30 meg line (usually it will be 30m'bits'ps), you'll be able to support only 15 users, max.

You can use a bandwidth manager / Packet shaper to provide reserved and dedicated bandwidth for critical applications such as the email. The rest of the application will share the remaining available bandwidth.

I personally don't think all users will require dedicated 256Kbps, unless they are using VoIP or streaming constantly.
General email and web browsing should provide acceptable performance even at around 64Kbps.

Hope this helps.

Warm regards,
