摘要： A hybrid satellite-mesh network including a ground segment, a mobile segment and a satellite segment provides high bandwidth communication between mobile platforms and the Internet. The satellite segment is used only when mesh network communication links between mobile segment nodes and ground segment nodes are unavailable. Mobile segment nodes can function in either an access terminal mode or an access point mode to communicate with other mobile segment nodes according to a routing algorithm in a mesh portion of the network. Mobile segment nodes employ adaptive frequency reuse, link level date rate adaptation, link level power control and adaptive beam forming antennas.

摘要： Systems and techniques are disclosed relating to wireless communications. The systems and techniques involve wireless communications wherein a process, module or communications terminal schedules communications. The scheduling function may include scheduling an inter-piconet transmission between first transmitting and receiving terminals including scheduling a power level for the inter-piconet transmission that satisfies a target quality parameter at the first receiving terminal. The scheduling function may also include scheduling an intra-piconet transmission between second transmitting and receiving terminals, including scheduling a power level for the intra-piconet transmission that satisfies a target quality parameter at the second receiving terminal. The intra-piconet transmission may be scheduled simultaneous with the inter-piconet transmission.

摘要： A first network node may include a wireless transmitter, a wireless receiver, a user interface and a controller. The controller may be configured to cause information that is received by the receiver to be delivered to the user interface, if that information is encoded to be delivered to the user interface of the network node. The controller may also be configured to cause information to be transmitted in a format encoded for a first target node by the transmitter, if that information is encoded to be forwarded by the network node. The controller may also be configured to cause information from the user interface to be transmitted in a format encoded for a second target node by the transmitter. Related processes are also disclosed.
