VoIP WLAN – Capacity planning of voice networks + traffic planning

Hi,

I’m learning about the topic of Capacity planning of voice networks & traffic planning (home applications & network demands) and hence I?m looking so some good, easy to understand information on the topic and even better if any one can give me an overview of what the topic is really ?about?? I was hoping to find some experts in the field?

For example what sorts of things are involved in planning for VoIP for WLAN, for a small business or home network..?

Also are there any apps out there that can assist with this planning process???

Also what is the difference between traffic and capacity planning?

Any help would be much appreciated!

Cheers,

NW
