iDirect Technology – Evolution Platform: iDirect, a company’s satellite-based IP communications technology enables constant connectivity for voice, video and data applications in diverse and challenging environments.

iDirect use DVB-S2, ACM, DOCSIS, Ku and C-Band technologies. Furthermore, they integrate proven third party applications with RASCOM-QAF1R satellite communications equipment if necessary, to satisfy customer needs.

iDirect offers a full line of satellite remote routers to suit any business requirement. The iDirect router is a single box solution that includes a satellite modem, IP router, optional encryption and TCP optimization over satellite and QoS/Prioritization. This below, you can find a list of the proposed products:

Evolution® X1 Satellite Router:

The Evolution X1 is optimized for use in large networks with small inbound channels such as SCADA (Supervisory Control And Data Acquisition), pipeline monitoring, point-of-sale and ATM. The X1 features DVB-S2/ACM, TDMA, basic routing and VLAN functionality at a cost-effective price point.

Evolution® X3 Satellite Router:

Evolution® X3 is the next generation satellite router featuring iDirect’s highly efficient implementation of the DVB-S2 standard. The Evolution® X3 Satellite Router is ideally suited for broadband requirements such as Internet and VPN access to enterprise networks, as well as real-time VoIP and video conferencing.

Evolution® X5 Satellite Router:

The Evolution® X5 features dual mode operation of DVB-S2/ACM or INFINITI® TDM on the outbound and deterministic TDMA on the in-bound. With fast processing capabilities, the X5 supports high speed, high-efficiency applications such as enterprise connectivity, mobile cellular, maritime and other mobile applications.


Newtec Technology: offers extensive industry’s solution set across three product lines consisting of Professional Equipment, Broadband Systems and IP Software Solutions.

Newtec use the FlexACM technology that allows for the implementation of the DVB-S2 Variable Coding and Modulation (VCM Mode). In VCM, each service is modulated with its own set of fixed parameters; chosen in according to the characteristics of the corresponding receive station.

FlexACM is a unique end-to-end solution for implementing ACM technology, IP shaping, compression and acceleration in a very efficient way for IP truck and IP backbone satellite segment while also guaranteeing a 100% link availability.


Datum Systems Technology: is a small, but highly respected company in the heart of Silicon Valley that designs and manufactures innovative satellite communications ground equipment for SCPC, MCPC and VSAT point-to-point or point-to-multipoint networks.

They specialize in reliable high performance satellite modems for a variety of Government and Commercial applications, including IP data, VOIP, cellular backhaul, banking, distance learning.

The PSM-500 is Datum System Systems latest modem series intended to replace and surpass the features and performance of the very popular PSM-4900, while being completely backward compatible.

The PSM-500 modem uses all of Datum System Systems proprietary design implementations to achieve the best performance and reliability in the industry. The PSM-500 is a variable data rate programmable satellite modem with 70 MHz or 140 MHz IF options. It is available in 3 firmware upgradeable feature sets, the M505, M511 and the M523, which also includes data rates up to 29.52 Mbps. In addition to standard BPSK, QPSK or OQPSK, the PSM-500 can be upgrade via firmware to add 8PSK, 8QAM or 16QAM. This modem is capable of having a wide variety of FEC configurations, including Viterbi (standard), Turbo and super performance LDPC.


Comtech Technology: There Advanced VSAT Solutions portfolio provides high-performance satellite-based communication solutions for a diverse range of applications adapted to any costumer.

They propose mobile backhaul with RAN optimization, IP trucking and backhaul, maritime and offshore networks, corporate and enterprise networks, emergency networks.

The 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 combination of advanced forward error correction with ACM/VCM, lossless payload compression, RAN and WAN optimization, advanced QoS and dynamic bandwidth management permit to:

  • Reduce OPEX by minimizing leased bandwidth;
  • Reduce CAPEX by reducing antenna size and BUC size;
  • Reduce OPEX and CAPEX by minimizing power consumption.
