GVF HTS Round Table Event

Denis SutherlandExcitement levels surrounding High Throughput Satellites (HTS) deployments remain high throughout the globe, as confirmed last week with a very impressive turnout at the GVF HTS 2015 London Roundtable.

The theme of the event was High Throughput SatellitesGame-Changer or New Game? The event explored a range of issues relating to the growth opportunities in the market for satellite-based broadband solutions.

Many conversations focused on a look forward to such future satellite constellations and large-scale satellites as:

  • Inmarsat GX: A seamless global platform for high-speed Ka-band satellite services, covering virtually everywhere on Earth and targeted at both the mobility and fixed markets.
  • IntelsatOne Flex: A high-performance wholesale Mbps managed service on Intelsat EPIC as well as wide-beam Ku-Band capacities. Service providers will be able to control their networks across multiple spot beams through customization of their own service plans and QoS prioritizations.
  • Telenor THOR 7: This will deliver a Ka-band HTS payload of up to nine Gbps of throughput across 25 spot beams over the North, Mediterranean and Baltic Seas.

These exciting programs represent the first global deployments of iDirect Velocity, which is designed to enable the global delivery of high-performance capacity over spot-beam satellites. We’ve addressed new HTS challenges such as spot-beam architecture, high-speed mobility, global coverage, higher throughput performance and carrier-class redundancy.

By Land, By Air, By Sea I had the chance to jump firsthand into these conversations during the panel discussion titled: HTS Mobility Application in the Air, at Sea, on Land. The discussion gave me the opportunity to talk about global bandwidth management, which is one of key features of iDirect Velocity. This allows satellite operators to stitch together multiple spot beams as one unified bandwidth pool, then offer managed Megabits per second (Mbps) services to customers across the total bandwidth pool, rather than operating strictly within individual beams.

Service providers can manage their own bandwidth pool, or can offer pre-defined Service Level Agreements (SLA) to service providers. In turn, service providers can operate simultaneously on both Evolution and iDirect Velocity, managing a blended portfolio using dual-mode remotes.

Of course, not to be overlooked are the RF enhancements that are being made on the iDirect Evolution® platform.

Forthcoming innovations in this area will involve the introduction of higher MODCODs, such as 32APSK, a subset of the new DVB-S2 standard, and enhanced, more granular FEC rates. Implemented in concert with both linear and non-linear pre-distortion, this innovation will enable iDirect partners to realize impressive efficiency and performance gains when operating on fully saturated transponders.

RF Efficiencies

In summary, the GVF HTS 2015 London Roundtable had some very meaningful future-looking discussions around HTS. However, many in the industry are still considering the near-term opportunities that HTS will bring. As a partner iDirect has much in store to ensure our partners have a seamless effort when it comes to bringing HTS to market.
