Throughout the past two decades, the telecommunications industry has transitioned from delivering dedicated circuits to now providing end-to-end services. Access networks are converging onto a common architecture, and satellite is following a similar course with full network convergence in its sights. However, when it comes to the defence and security sector, the idea of full network convergence becomes a bit more complicated.
The access landscape for defence looks like such: defence satellite Ka, Ku, X, commercial satellite Ka, Ku, C, and terrestrial access networks. Add to this the variety of infrastructure of secured teleport and commercial teleport, and you begin to see where things get a bit more complicated.
Let’s paint the picture with a common scenario. A national ministry of defence wants to launch a Ka-band defence network. It may wish to operate on a commercially available platform to cover the areas of operation that are not covered by its own satellite network. Roaming onto the other satellite networks might be an ideal choice.
However, this requires a level of management and control across satellite networks of various operators. This level of interoperability doesn’t quite exist today.
Of course, interoperability challenges are coupled with other challenges, including the high cost of capacity, no common management plane and interface, and ease of use and performance.
