-The Wireless Wide-Area-Network interface provides access (through a wireless
-modem/wwan) to wireless networks provided by various cellular providers.
+:abbr:`WWAN (Wireless Wide Area Network)` interfaces provide access to cellular 
+networks via a cellular modem or card. 
 
-VyOS uses the `interfaces wwan` subsystem for configuration.
+Configure these interfaces under the ``interfaces wwan`` node.

-All available WWAN cards have a built-in, reprogrammable firmware. Most vendors
-provide regular updates to firmware used in the baseband chip.
+WWAN modules include reprogrammable firmware, and most vendors regularly 
+provide updates for it.
 
-As VyOS makes use of the QMI interface to connect to the WWAN modem cards, the
-firmware can be reprogrammed.
+Since VyOS communicates with these devices via the QMI interface, you can 
+update firmware directly within the system using the ``qmi-firmware-update`` 
+utility.
 
-To update the firmware, VyOS also ships the `qmi-firmware-update` binary. To
