Starlink-based ones have enough bandwidth for the whole plane to have workable bandwidth (just rate-limit based on client so no single heavy user hogs the entire bandwidth).
There's also an European one whose name currently escapes me which uses a custom flavor of LTE and special ground stations that also happily provides hundreds of mbps.
Capacity is primarily an issue on the legacy BGAN-based ones where you have a handful of mbps for the entire plane.
EAN is a joint venture between Inmarsat (now Viasat) and Deutsche Telekom. The system uses a combination of ground based LTE and satellite connectivity.
