Apple cluster control is a technique for centrally managing and batch-operating multiple iPhones from one computer, with no jailbreak and no signing.
This one answers: How Should Apple Cluster Control Connect? USB vs WiFi.
When USB makes sense
- Central rack management and long mirror sessions
- You want the most stable wired link
When WiFi makes sense
- You don’t want cables on every phone
- The phone and cluster PC share the same LAN
See the comparison in the connection guide. If unsure: connect one phone over USB first, then decide whether WiFi is worth the convenience.
