What You Need To Know - ZyXEL Communications LTE3311 series User Manual

6.3 What You Need To Know

The information in this section can help you configure the screens for your WAN connection, as well
as enable/disable some advanced features of your LTE3311.
3G
3G (Third Generation) is a digital, packet-switched wireless technology. Bandwidth usage is
optimized as multiple users share the same channel and bandwidth is only allocated to users when
they send data. It allows fast transfer of voice and non-voice data and provides broadband Internet
access to mobile devices.
4G
4G is the fourth generation of the mobile telecommunications technology and a successor of 3G.
Both the WiMAX and Long Term Evolution (LTE) standards are the 4G candidate systems. 4G only
supports all-IP-based packet-switched telephony services and is required to offer gigabit speed
access.
DNS Server Address Assignment
Use Domain Name System (DNS) to map a domain name to its corresponding IP address and vice
versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely
important because without it, you must know the IP address of a computer before you can access
it.
The LTE3311 can get the DNS server addresses in the following ways.
The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you
1
sign up. If your ISP gives you DNS server addresses, manually enter them in the DNS server fields.
If your ISP dynamically assigns the DNS server IP addresses (along with the LTE3311's WAN IP
2
address), set the DNS server fields to get the DNS server address from the ISP.
