• A Packet-Switched (PS) connection to the Internet
• A Circuit-Switched (CS) dialed connection for voice
• Short Messaging Service (SMS)
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 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
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. The
signal is uncompressed 3.1 kHz audio, which allows for optimum voice quality.
•ISDN. A high quality connection which can be used for voice (3.1 kHz Audio), G4 fax or 64 kbps
UDI/RDI data. This service is not available with the EXPLORER 325.
SMS service
The BGAN system provides a Short Messaging Service (SMS) for sending and receiving SMS
messages to and from the terminal.
Note
The BGAN system supports maximum 11 concurrent PS connections at a time per
