WPA3 enterprise support

Hello Team,

This is a question related to Wi-Fi connectivity and authentication support for the same.
In the web site it mentioned that,
Authentications support as defined in 802.11i:

  • Open
  • WPA (Wi-Fi Protected Access)
  • WPA2 personal and enterprise
  • WPA3 personal and enterprise with 128-bit encryption suite (192-bit encryption not supported)
    Can you please explain the difference between 128bit encryption and 192bit encryption. How does this matter for the connectivity of devices?

Thanks in advance
Dipin
