Yes, inter-satellite links (ISL) can be used for networking and routing between satellites. However in Rel-17, the focus has been on bent-pipe satellite payloads, i.e.. satellites that act as relays where the ground-station is the actual base-station – so first the focus in a future release needs to switch to regenerative payloads i.e. base-stations onboard the satellite – and then to ISL later. Nothing hinders ISL at the moment – it is just not standardized.
