You can always determine the Bandwidh requirement for WAN connectivity well in advance. The followings points are to be considered to decide the requirement:

1. What are services you are looking at i.e Voice, Video and data. Voice can be hotlines, VoIP, IP Telephony, etc. Video can be Video using Web Camera or dedicated video communcation using video conferencing equipment. Data services can be FTP, Internet sharing, e-Mail, etc.

2. How many clients or nodes in the LAN would be sharing the WAN bandwidth, like is it shared equally by all the nodes or only server will be sharing the bandwidth.

3. What are the data applications? The bandwidth needed depend on the type of applications you want to implement, like sharing or transfering of Database files, text files, media files, GIS data, etc. Also it depends on the response time you need, if the applications depend on response time then you have to go for a higher bandwidth to have a quick response time.

Based on the bandwidth decided and the budget you have planned for the project you can go for a dedicated Leased line Network or WAn using ISDN links or VPN from any of the ISPs in your location.

I think now you can determine the Bandwidth using the above input. If you still have a problem, please furnish the details as mentioned in the above queries, so that I will calculate the Bandwidth required.

Please mail me back incase you need any more clarifications.

All the best.
