Simulations require high-speed Internet access (DSL/cable modem quality). In general, the bit-rate supported should be higher than (or considerably higher than) a 56 kbit/s modem. If you're accessing it wirelessly, you need to make sure you have enough ports on your end to support the number of users who will try to access the simulation at the same time.

Our simulations are web-based products. They cannot be hosted locally. If your institution does not have adequate bandwidth to support access to the eProducts, your ability to use the simulations would have to be reconsidered. Please ask your IT group to enable any and all access (regardless of file size) to the '' and '' domains. You should also check with the service provider to make sure that it can handle several hundred users.  There are other factors, such as IP address allocation, that need to be large enough capacity to support a multi-hundred person group.

There should be no issues with multiple concurrent teams and bandwidth using a simulation. The issues we have seen are local (at the school) issues concerning the school’s own bandwidth limitations. If multiple students are playing the videos at the same time, since the videos are by-far the largest bandwidth element of the simulation, there can be performance problems. There are ways to mitigate this risk, such as assigning the ‘Prepare’ section as homework the night before play or projecting the videos in front of class to minimize how many individual students play them. It is recommended to work with your IT group to assess bandwidth constraints and wired/wireless capabilities.
