Hi,

You can use the new SNMP service to monitor the bandwidth at your hotspot and see if you need to increase or reduce the existing bandwidth: http://hotspotsystem.blogspot.hu/2012/08/introducing-snmp-monitoring-service-beta.html

I suggest you use this bandwidth calculator to get a good estimate of your bandwidth requirements: http://www.bnecomputers.com/network-bandwidth-input.html
