Infrastructure mode is a wireless network framework that has a central WLAN access point / router at the heart of the network.
If you configure your Brother machine, it can connect to a WLAN access point/ router.
In infrastructure mode, wireless devices communicate with each other through a WLAN access point/router.
When the Brother wireless machine is part of infrastructure mode network, you can see and delete the scanned image from Smartphone, PC and mobile device via a WLAN access point / router.
