Packet data service
The BGAN network supports different classes of data connection to the Internet.
• Using a
Standard IP
connection several users can share the data connection
simultaneously. This type of connection is ideal for e-mail, file transfer, and Internet and
intranet access. The user pays for the amount of data sent and received.
• Using a Streaming IP connection you get an exclusive high-priority connection that
ensures seamless transfer of data. This type of connection is ideal for time critical
applications like live video over IP. The user pays for the duration of the connection (per
minute charge).
Circuit-Switched (dialed) service
The following types of circuit-switched connection are available:
• Standard Voice. A low-tariff connection for voice only. The voice signal is compressed to
4.0 kbps, which reduces the bandwidth use and consequently the tariff.
•
3.1 kHz Audio
. A high quality connection which can be used for Premium Voice or G3 fax.

that the 3.1 kHz Audio service may have a much higher tariff than Standard Voice.
