Communication system with multi band gateway
First Claim
1. A method of operating a satellite, comprising:
- using a first frequency band for a feeder link between a gateway and the satellite while using a user frequency band for a user link between a set of user terminals and the satellite in order to send information between the gateway and the set of user terminals;
using a second frequency band for the feeder link between the gateway and the satellite while using the user frequency band for the user link between the subset of the user terminals and the satellite in order to send information between the gateway and the subset of the user terminals, the second frequency band has a lower capacity than the first frequency band;
in response to identifying a problem with the first frequency band, switching from using the first frequency band to using the second frequency band for the feeder link between the gateway and the satellite while using the user frequency band for the user link between the user terminals and the satellite; and
the using the first frequency band, the using the second frequency band and the switching are performed by the satellite.

Abstract
A satellite includes a first communication path for communicating with one or more gateways using a first frequency band while communicating with a set of the user terminals using a user frequency band and a second communication path for communicating with the one or more gateways using a second frequency band while communicating with at least a subset of the user terminals using the user frequency band. The second frequency band has a lower capacity than the first frequency band. Communication between the one or more gateways and the satellite can be switched between the first communication path and the second communication path for any of a number of reasons including as part of an incremental roll-out of services, in response to degradation in link quality or other reason.
