      [Via Satellite 12-19-13] ViaSat has successfully demonstrated full-mesh multi spot beam (fan in/fan out) operations over the government-owned WGS 1 satellite with LinkWayS2 equipped Earth terminals configured with the WIN-T software baseline. This demonstration was a collaboration between the U.S. Army and ViaSat aimed at improving the efficiency of multi spot beam operations over the Wideband Global Satcom (WGS) constellation.

      Earth terminals in the Guam, Hawaii, and West Coast WGS beams that were equipped with LinkWayS2 participated in the weeklong demonstration. Using a single TDMA carrier, full-mesh connectivity was demonstrated between all traffic terminals, both interbeam (e.g., Hawaii-to-Guam, Hawaii-to-Roberts, etc.) and intrabeam (e.g., Hawaii-to-Hawaii, Roberts-to-Roberts, etc.). ViaSat and the Army set up the same connections using multiple TDMA carriers configured in the same bandwidth segment on WGS 1. The system is scalable from one TDMA carrier to multiple contiguous crossbeam TDMA carriers and multiple non-contiguous in-beam carriers.
