An apparatus and method of communication in a network includes a hub having a burst time plan generating section to generate a burst time plan including time slot allocation information that allocated transmission time slots in a subsequent frame to remote terminals. The allocation information identifies at least one time slot in the subsequent frame as a dummy time slot assigned to at least one remote terminal already acquired in the network. The hub also includes a transmitter to transmit the burst time plan including the allocation information. A corresponding remote terminal and computer readable media are also discussed.

A rain diversity switchover system includes a diversity Satellite Access Station (SAS) including a transmitter modem and a receiver modem in communication with a satellite. The system further includes a primary SAS including a transmitter modem and a receiver modem in communication with the satellite via a second satellite antenna, where the transmitter and receiver modems of the primary SAS are synchronized with the transmitter and receiver modems of the diversity SAS via a common time source. Further, a hub data processor adjusts a timing of transmissions from the diversity SAS to the satellite relative to the common time source in accordance with a difference between a time of flight from the diversity SAS to the satellite and a time of flight from the primary SAS to the satellite. Additionally, a switchover controller controls a rain diversity switchover between the primary SAS and the diversity SAS.

Method and apparatus for satellite communication with baseband switching over an IP network

A resonator filter assembly is provided having a first wafer (), a second wafer () and a third wafer (). A plurality of pits are etched in the first and second wafer () and arranged such that a plurality of resonant cavities () are formed with a coupling cavity () disposed between the resonant cavities (). By altering the dimensions of the resonant and coupling cavities (), the frequency characteristics of the filter can be adjusted as desired.
