Comtech EF Data


Our Advanced VSAT Solutions portfolio provides high-performance satellite-based communication solutions for a diverse range of applications, including mobile backhaul with RAN optimization, IP trunking and backhaul, maritime and offshore networks, corporate and enterprise networks, emergency and disaster recovery. Incorporating advanced technologies developed by Comtech EF Data, AHA Products Group, Memotec and Stampede, the solutions provide unmatched performance, industry-leading bandwidth efficiencies and network optimization – while minimizing Total Cost of Ownership.

The Advanced VSAT hub provides:

  • DVB-S2 outbound transmission with ACM/VCM
  • VersaFEC® return channel reception with ACM
  • ACM / VCM controller
  • Packet processing and optimization including quality of service (QoS), header compression and lossless payload compression
  • E1 aggregation and RAN optimization
  • WAN optimization
  • Network management system
  • Dynamic bandwidth management (dSCPC)
  • Redundancy

The remote terminal provides:

  • DVB-S2 outbound reception
  • VersaFEC return channel transmission with ACM
  • Packet processing and optimization including QoS, header compression and lossless payload compression
  • RAN optimization – integrated E1 RAN optimization or external RAN optimization
  • WAN optimization

The remote terminals are based on the CDM-840 Remote Router or the outdoor versions, the ODM-840 and the ODMR-840. The CDM-840 and the ODM-840 support integrated E1 RAN optimization for one E1. If required, the Memotec CX-U 1010/1220 can be used to support multiple E1s. The Stampede FX-1000 can be used to add WAN optimization and application acceleration. And, the Vipersat Roaming Oceanic Satellite Server (ROSS) adds global roaming capability for maritime users.

The Advanced VSAT Solutions are designed to minimize the total cost of ownership. The combination of advanced forward error correction with ACM/VCM, header and lossless payload compression, RAN and WAN optimization, advanced QoS and dynamic bandwidth management:

  • Reduces OPEX by minimizing leased bandwidth
  • Reduces CAPEX by reducing antenna size and BUC size
  • Reduces OPEX and CAPEX by minimizing power consumption
