Packet data service
The BGAN network supports different classes of data connection to the Internet.
• Using a Standard data 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 data connection, you get an exclusive, high-priority connection, ensuring
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
Two 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, G3 fax,
analog modem or ISDN.
The signal is uncompressed 3.1 kHz audio, which allows for optimum voice quality.
