3.7.4 Data Services
The five types of Packet Switched data connections (Network Connections) consist of a Background data service,
and four Quality of Service (QoS) Streaming services.
Background Service : A Background connection shares the bandwidth of the satellite spot beam with all the other
active background connections in the spot beam, minus all the bandwidth allocated to streaming connections.
Background connections can reach up to 492 kbps for the RF-7800B-VU104, and up to 432 kbps for the RF-7800B-
DU024. For usage such as Email and Internet browsing, usually a Background connection operates at a higher data
rate and less cost than a Streaming connection. Background service rates are charged by the amount of MegaBytes
transferred across the network.
Streaming Service : A Streaming data connection acquires a dedicated amount of bandwidth from the satellite spot
beam to ensure a minimum amount of guaranteed QoS of data throughput for that connection. The Streaming
Service allows the ability for data rates of 32 kbps, 64 kbps, 128 kbps, or 256 kbps. The RF-7800B-VU104 can
operate at Streaming rates of up to 256 kbps, whereas the RF-7800B-DU024 can operate at streaming rates of up to
128 kbps.
Streaming channels may be preferred when transferring video teleconferencing across the network. Streaming
service rates are charged by the amount of minutes the connection is up on the network. Refer to your BGAN Service
Provider for associated costs.
It should be noted, that International Marine/Maritime Satellite (INMARSAT) guarantees the QoS of the stream up
to where their private network meets the public Internet. It is up to the customer to make arrangements to maintain
the QoS over the Internet to the final destination.
Each device connected to the BGAN terminal can have its own primary Network Connection (e.g. background or
streaming connection). Up to 11 devices may be connected to one BGAN terminal at a time. Each device will have
a separate global IP address to the network.
3.7.5 Virtual Private Network (VPN) Connections
When a computer establishes a VPN connection from their computer, through the BGAN terminal, to a remote
network, all data going to or through the BGAN terminal will be encrypted. Thus, after the VPN is established, that
same computer will not be able to remotely control the BGAN terminal using the embedded Web interface. Thus,
ensure all BGAN terminal settings are as required prior to establishing the VPN connection.
