Speed ​

​1. Outroute: DVB-S and High Speed DVB-S2

Implementing DVB-S2 on the new system will result on better performance and network system efficiency. Some features available in the Hughes VSAT-IP System to support bandwidth efficiency and system reliability include:

  • Low Density Parity Check (LDPC), which is more efficient than Forward Error Correction (FEC)
  • Adaptive Coding and Modulation (ACM), which can make changes dynamically and automatically on FEC coding rate and modulation according to the weather condition and geographic location of each site, allowing stable communication network by minimizing the disturbance.
  • DVB-S2 with 8-PSK Modulation can let through greater data throughput.
  • Outroute data rate support up to 121 Mbps. Outroute symbol rate: 1-45 (in 1 Msps steps)

 

2. Inroute: High Speed ​​Inroute

Using highly efficient turbo-coded that can support up to 3.2 Mbps information rate

Inroute symbol rate: 128, 256, 512, 1024, 2048 kbps

3. Hughes HX remote terminal is standardized with ETSI, RTTE, ITU-R and TIA.
