Carrier Aggregation (CA) is a technology to deliver high downlink data rates by combining more than
one carrier in the same or different bands together.

Ethernet WAN
If you have another broadband modem or router available, you can use the Ethernet WAN port and
then connect it to the broadband modem or router. This way, you can access the Internet through an
Ethernet connection and still use the Firewall function on the Zyxel Device.
See Section 1.1.1 on page 17 to see if your Zyxel Device supports an Ethernet WAN port.
