Carrier Aggregation (LTE7480-M804 / LTE7490-M904/ LTE5388-M804 / LTE5398-
M904 / LTE3316-M604)
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.
Figure 2 Zyxel Device’s CA Application
Ethernet WAN (LTE3301-PLUS / LTE5388-M804 / LTE5398-M904 / LTE3316-M604)
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 via an
Ethernet connection and still use the Firewall function on the Zyxel Device.
Note: For LTE3301-PLUS, convert LAN port number four as a WAN port first. See Section 6.4 on
page 90 for more information about the Network Setting > Broadband > Ethernet WAN
screen.
Note: For LTE5388-M804 / LTE5398-M904 / LTE3316-M604, convert LAN port number one as a
WAN port first. See Section 6.4 on page 90 for more information about the Network
Setting > Broadband > Ethernet WAN screen.
