Giga Is ITU and UNICEF's School Connectivity Project

They want to spend $429B to link up 6M schools. That's a cost of $71K a school.

It looks like Starlink is $17,000 for ten years of service, so even if you were to add a few thousand dollars for installation, there's a lot of overhead there.

It does strike me that a top-down approach seems more costly than a model that allows schools to get grants.

This reads as extremely centralistic and patronizing. Just provide a web form where schools can apply for funds. Have a local representative visit them and describe the local situation to allow a small central team to allocate suitable funds.
