Published purpose

Satellite operators lease out bandwidth for uses like cellular networks and internet services. The bandwidth provided by a satellite becomes fragmented over time, as leases expire and are replaced by new leases that do not always use exactly the same bandwidth. This results in portions of the bandwidth being unattractive to new users, because it is not sufficient for their needs. This project will explore how to use channel bonding to combine this under-used bandwidth and improve satellite operations. It will design and produce a prototype of a channel bonded modem that gathers under-used bandwidth on satellite modems to produce high output signals to increase communication performance. This project will benefit satellite operators and end users by allowing under-used bandwidth to be sold at preferred rates, which in turn would provide a cost-effective option for remote communities that are reliant on satellite communications. In addition, extra communication security will result from spreading signals across multiple channels and satellites, which makes it harder to intercept sensitive government or defense communications.
