  • Overview

    Today, Evolution remains the #1 platform in the high-end corporate networking segments of the market and is installed on more vessels, airlines, tactical military vehicles and drilling rigs than any other*.

    The fundamental value of Evolution lies in the extremely tight integration of the hardware and software architecture with a dynamic feature set that makes it highly flexible in its ability to handle diverse market needs — enabling everything from basic Internet and VoIP, to highly sophisticated application suites such as video conferencing and digital signage in fixed and mobile environments alike.

    ST Engineering iDirect is advancing the Evolution platform by continuing to innovate in three key areas: increased remote performance, RF efficiencies and scalability. With Evolution, customers can invest in an innovative technology mindset aligned with a long-term business strategy.

    Evolution is the leading platform in:

    • Maritime with 60% market share
    • Aero with 46% market share
    • Military/defense with 41% market share
    • Enterprise with 36% market share
  • Features

    Flexible, Efficient Core Architecture

    ST Engineering iDirect hub can connect to any frequency band on all satellite architectures. Evolution is built on DVB-S2/S2X with ACM with Adaptive TDMA and multiple efficiency technologies such as reduced Roll-off-Factors and enhanced waveforms, to allocate bandwidth efficiently over distributed networks, while automatically adjusting to dynamic traffic demands and changing network conditions.

    Modular Design for Scalability

    The modular hub and line card system enables operators and service providers to minimize initial capital costs, offer multiple service types from a central hub, and scale business one network at a time in a “pay as you grow” manner. It also allows Service Providers to operate across all business models, including VNO and managed service models and easily add new capabilities with over-the-air software upgrades.

    Integration with Terrestrial Networks

    Evolution mirrors the quality and reliability of terrestrial services, ensuring an enterprise-class user experience, and can operate seamlessly as part of an integrated global IP network. ST Engineering iDirect’s VLAN and Layer 2 over Satellite (L2oS) features enable a satellite network to behave like a mainstream access network.

    Advanced Quality of Service and Reliability

    ST Engineering iDirect’s QoS technologies allows for countless possibilities of quality of service levels, bandwidth management and traffic prioritization. GQoS provides network operators a significant increase in bandwidth management capabilities when prioritizing traffic for customers in a shared network environment. This results in more flexibility with traffic configuration and prioritization, more savings over conventional QoS, and improved customer service quality.
    Evolution’s hub diversity and redundancy and seamless network failover protects overall network integrity and delivers carrier class reliability.

    Data Security

    Evolution supports Advanced Encryption Standard (AES) for commercial applications, as well as advanced military security standards, such as TRANSEC and FIPS 140-2 compliance.

    Mobility Capabilities

    Industry-leading mobility functionality lets operators and service providers capitalize on emerging maritime, government and defense, and land mobility markets. The platform includes a number of features to support deployment of mobility terminals such as on trains, buses and vessels. These features include automatic beam switching (ABS), Global NMS, spread spectrum waveforms, fast reacquisition after blockage, skew angle mitigation, handling for the Doppler effect and OpenAMIP.

  • Evolution 4.1.3 software rounds out the advanced capabilities of ST Engineering iDirect’s iQ Series remotes with 16QAM modulation for ATDMA return rates up to 40 Mbps, link encryption and Multicast Fastpath encryption for secure transmission, and support for the new iQ LTE Series for hybrid VSAT-LTE use cases.
