GERMANTOWN, Md., June 25, 2012 /PRNewswire/ -- Hughes Network Systems, LLC (HUGHES), the global leader in broadband satellite networks and services today announced that its HX System employs the new IP-over-Satellite 1008-B air interface standard (IPoS-B), which was recently approved by the Telecommunications Industry Association (TIA).

        mesh-specific timing synchronization
    --  Direct sequence spreading to small antennas in a mobile environment
    --  Video Broadcasting - Second Generation (DVB-S2)-compliant modulation and
        coding
    --  Adaptive Coding and Modulation (ACM) and Constant Coding Modulation
        (CCM) on the outroute
    --  Adaptive Inroute Selection (AIS) of coding rate
    --  Mobility support
    --  Inroute control signaling security
    --  Closed Loop Timing (CLT)
TIA is accredited by the American National Standards Institute (ANSI) as a standards developing organization. Hughes also adheres to standards set by the European Telecommunications Standards Institute (ETSI) and ITU.
