Definitions for network terms
APN (Access Point Name)
APNs are provided from the Airtime Provider. They may also be defined on the SIM
card. The APN is used by the network user to establish a connection to the required
external network. This means that the terminal must know the APN in order to be
able to connect to the external network.
Header compression
The Header of a data packet contains control information belonging to that packet.
The information in the Header can take up a considerable amount of bandwidth. In
order to save bandwidth, you can use Header Compression, meaning you compress
the header information, leaving some of the information out.
You can select whether or not to use Header Compression for your data
transmission.
NAT (Network Address Translation)
NAT enables a local-area network to use one set of private IP addresses for internal
traffic and an assigned or static IP address for external traffic. The built-in NAT
module in the terminal makes all necessary address translations between the local-
area traffic and the external traffic.
If more than one user is connected, you must select a network user group with
Router mode
to use the NAT of the terminal.
