Abstract: Two devices can be connected for communication by a wireless connection, where those devices will function as master and slave devices with respect to that connection. A slave device to a connection can perform changes to the connection on behalf of an application, subsystem, or other such source on either the slave device or a master device. These changes can include changes to connection parameter values, or can include state changes such as to perform a disconnect action. Enabling the slave device to perform these actions can help to bypass any restrictions that would otherwise prevent these actions being performed from a master device to the connection.

The optimization process considers the spatial distribution of all cochannel users in the footprint of the satellite. The user beam adapts to the user's location and co-channel interference environment.
