Technical Information

RedVu prides itself on being technically advanced and yet easy to use. We offer state of the art communications solutions that help put your mind at ease when you are underway.

RedVu’s services and solutions are compatible with most of the existing Ku-band Vsat antennas presently installed, including Sea Tel’s 4006, 4009, 5009, and 6009 systems. 

There will be some hardware changes to the indoor equipment to allow automatic beam switching and remote management, and allow the system to connect to our network.  Please contact us if you have any questions about converting to a RedVu services plan.

If a Ku-band maritime Vsat system is not installed we offer great deals on new Sea Tel equipment; the majority of our satellite coverage area supports the use of antennas as small as 30 inches in diameter, so for most applications Sea Tel’s Model 3011 systems or larger are appropriate.  Operation in the Pacific Ocean Region currently requires somewhat larger antennas, so if you are planning a trip to this area our recommendations would be slightly different than if you were staying in the Americas or European areas.

RedVu’s broadband services are sold thru our dealer network.  Please contact us for a dealer in your area.  If you have a marine electronics dealer that you are happy with, please let us know and we will try to work with them to provide RedVu products and services.

RedVu’s service plans are flexible, cost effective and affordable.  Ship in-bound speeds range from 256 to 3072 kbps and ship-outbound speeds of 128 to 1024 kbps are availabie. 

Our customers can easily move between our plans when their communications needs increase or decrease.  As an example for the yachting market, our speeds can be increased, CIR (guaranteed and unshared bandwidth) can be added, and contention ratio decreased when the owner or guests are onboard.  When the owner or guests depart, the speeds can be reduced to their normal contracted rate. 

For new Vsat antenna installations RedVu is a Sea Tel / Cobham stocking distributor and offer great antenna pricing.   Plus we have antennas in stock, ready to ship!

RedVu’s network is based on iDirect’s Evolution architecture.  This technology offers significant benefits to the end user.  These features and benefits include:

  • DVBS2 coding on the ship-inbound data service.  DVBS2 coding uses less bandwidth to support given data rates than prior technology.  This efficient use of bandwidth results in lower costs to the end user.
  • The Evolution network uses Adaptive Code Modulation on the ship-inbound service.  ACM helps maintain ship-inbound speeds to maintain connections, or use smaller antennas, during heavy weather events.  This makes the service more reliable for the end user.
  • Frequency hopping on the Ship-outbound channel helps reduce contention-ratio issues.  Frequency hopping is allowed between all the available ship-outbound carriers and it spreads the loading evenly between the outbound carriers.  In the past, the modem was assigned to a single outbound carrier, so you could have a situation where one carrier was fully loaded, and another carrier was only lightly loaded.

Frequency hopping doesn’t solve contention ratio slow-downs completely, as the only real solution is to lower the contention ratio or add CIR (Committed Information Rate).  This is why we offer two different contention ratio plans; 10:1 and 4:1, and offer the ability to add CIR, which is unshared-bandwith, as required.

The iDirect network groups end-users together in ship-outbound channels, with each channel having a fixed bandwidth.  512 kbps outbound channels are common, with a number of clients sharing this outbound channel.  This number of clients sharing the outbound bandwidth is the contention ratio.   10:1 offers a good compromise between speed and cost.  At times there will be congestion on the outbound channel.  This means it may take a little longer than normal to send that email with attachments.   Normal VoIP telephone calls will not be affected as the VoIP hardware we use does not use much bandwidth. 

Skype uses a significant amount of bandwidth which is not supportable in loaded network conditions.
