Hub Side Fade

In the last blog, we left off discussing about rain fade and the possibility it could hit on the hub side.

Adaptive will help mitigate rain fade on the hub side of things, but from a hub reliability and redundancy standpoint these are becoming even more critical. The centralized nature of having all of your hub equipment in a single feeder link, typically at a single teleport or multiple teleports in different feeder links, leads to larger network sizes, and the need to have a lot more redundancy and reliability of the link, in general.

Utilizing Ka band as their uplink frequencies from the feeder links, this provides a challenge in being able to handle rain fades on the hub side. iDirect is introducing a feature that actually will allow a complete hub switchover from one hub to another hub located at a different location, seamlessly, that will allow the ability to overcome Ka band rain fade on the feeder links.

The battle of the bands will no doubt be decided by the service providers that deliver service with the HTS satellite. They will be the ones who buy terminals, with smaller or large reflectors, higher or lower data rates, and offer SLA that offer guarantee connectivity.

It is interesting to see service providers like Airbus and its strategy towards HTS; they are using Ku, Ka and L Band. End customers will focus on the data delivery, SLA and maybe the terminals SWAP, but probably not the Band.
