iDirect VSAT Networks
Evolution modem | Automatic Beam Switching ABS | Virtual Network Operator VNO | Adaptive Coding Modulation ACM |
ABS allows the remote modems to sense, via iDirect's OpenAMIP protocol with the antenna, when it is necessary to switch to another satellite. The modem then sets the antenna parameters and commands the antenna to target and track the new satellite, without any intervention from the onboard personnel.
With this feature, satellite operators can seamlessly join together several regional beams into contiguous, multi region coverage areas.
With iDirect/s Global Network Management System GNMS, the IP addressing scheme can be maintained, making the transition completely transparent to the user.
This VNO model also facilitates providing services in remote ocean regions uplinked to a different satellite from a different continent.
With Adaptive Coding Modulation the modem dynamically changes the modulation scheme to a more robust FEC, as the weather deteriorates, allowing communications to continue in the worst conditions, albeit at a lower rate.
For customers that cannot tollerate reduced speed, iDirect has a GQ0S that allows setting of a Extended Information Rate(EIR) that guarantees throughput at a certain level in the worst conditions, at a fee. Resources are taken from lower priced links, that are not being disadvantaged by the weather at that time, to boost the premium link to the required level.
ACM results in a substantial savings of bandwidth and money for the network operator and the customer while maintaining quality links.
