About bandwidth usage

The Scientific Learning programs vary in the amount of data transmitted and received based on multiple factors, such as the current exercise or reading selection, the protocol or schedule, and the current status in the program. Also, bandwidth requirements vary during an individual session, with larger data transfers occurring during the first few minutes of a session, and in the case of Reading Assistant/Reading Assistant Plus, after a recording session.

Tip: A good way to improve network bandwidth usage is to use a content sever. Content servers help reduce WAN traffic and increase performance by providing content at a local level. On average, a content server at the district or school level will allow 3 to 7 times more concurrent users where available bandwidth is a limiting factor. For more information see About content servers. Note that content servers are not currently supported when using Reading Assistant Plus (on any device), and are not needed when using the Fast ForWord program apps on iPad.
