Definitions for network terms<br />
APN (Access Point Name)<br />
4444<br />
The APN is used by the network user to establish the connection to the<br />
required destination network. This means that the terminal must know the<br />
APN in order to be able to connect to the destination network.<br />
APNs are provided from the Airtime Provider. They may also be defined on the<br />
SIM card.<br />
Header compression<br />
The Header of a data packet contains control information belonging to that<br />
packet. The information in the Header can take up a considerable amount of<br />
bandwidth. In order to save bandwidth, you can use Header Compression,<br />
meaning you compress the header information, leaving some of the<br />
information out.<br />
You can select whether or not to use Header Compression for your data<br />
transmission.<br />
• Header Compression enabled: Recommended for low-noise applications.<br />
If you select Header Compression enabled, you will be using less<br />
bandwidth on header information, leaving more bandwidth for the actual<br />
payload.<br />
However, if the environment is noisy, the system will have to retransmit<br />
information, and you may end up using more bandwidth than without<br />
Header Compression.<br />
• Header Compression disabled: Recommended in noisy environments.<br />
If Header Compression is disabled, the system will be less sensitive to<br />
noise.<br />

Profiles<br />
A profile is a collection of Quality of Service (QoS) settings and other settings<br />
defining the mode in which data is transmitted on an interface. For example, a<br />
profile is used to define whether a connection should be a Standard or<br />
Streaming connection.<br />
