Systems, devices, and methods are described for formatting packets for downstream satellite links. The generation of a broadband wireless signal is described, the signal to be transmitted between a gateway and subscriber terminals via satellite. Respective data link layer addresses for the subscriber terminals may each be associated with one or more shortened identifiers for use in lieu of the associated data link layer addresses. This addressing may be included in a stream encapsulation header for an appended data packet. One or more such headers and their appended data packets may then be encapsulated in a baseband frame for transmission within a physical layer frame. Data packets may be fragmented across physical layer frames, and a range of novel formatting techniques may be used to implement the fragmentation.
