Abstract: A node may include a receiver configured to receive signals transmitted from a gateway and a logic device coupled to the receiver. The node may also include a memory configured to store label information identifying a data packet stored in the node. The logic device may be configured to receive a message from the gateway, where the message includes label information, and access the memory to identify a data packet based on the label information included in the message. The node may also include a transmitter configured to transmit the data packet to the gateway over a channel shared with a number of other nodes.

Abstract: Methods of operating a transceiver including an antenna having a plurality of antenna feed elements are presented. The methods include defining a plurality of antenna gain constraint values gk associated with K geographic constraint points within a geographic region, iteratively generating M antenna feed element weights wM that result in antenna response values fK at the K geographic constraint points based on the corresponding antenna gain constraint values gK, forming an antenna beam from the antenna to the geographic region using the antenna feed element weights wM, and communicating information over the antenna beam. Related transceivers, satellites, and satellite gateways are also disclosed.
