Is cell data communication more secure than a public but password-protected wifi connection


@brandon WPA2 encrypts everything using the WiFi password, so everyone on the network can see what you do. WPA3 fixes that, every client is encrypted seperately. Cell data (like for example LTE) encrypts it for everyone seperately as well. Of course this is all pretty irrelevant since you shouldn't trust the network regardless of which you use (which is how the internet was designed)

@Matter @brandon WPA2 statement is correct for personal, not entirely correct for enterprise. Granted for say a coffee shop you are dealing with WPA2 personal. WPA3 brings the personal and enterprise profiles more in line so things are more consistent regardless of profile.
