«Satellite trunking» is referring to very different services and usages. Here, we define trunking as the provision of high data rate point-to-point links for professional use.
Up to now satellite trunking services (including mobile/cellular backhaul) are only provided by GEO satellites over regional coverage, with the notable exception of the equatorial O3B MEO constellation.
Mega-constellations are developed to provide Internet access services to private customers.
The future would be to rather use LEO/MEO constellations for the provision of high speed trunking services to professional customers.
The question is : will be LEO/MEO constellations the right solution for the next generation of high speed trunking services
