UT (User Terminal): The User terminal is the BGAN modem device (e.g. Hughes 9201, Hughes9350,
etc.).
USIM Card: Your BGAN Service Provider supplies you with a Universal Mobile Telecommunications
System Subscriber SIM (USIM) Card.
The USIM card is similar to the SIM Card that is commonly used in a GSM phone. The card
holds a microchip that stores information and encrypts voice and data transmissions, making
it extremely difficult to listen in on calls. The USIM Card also stores data that identifies the
caller to the BGAN Service Provider.
Virtual Private Network: A Virtual Private Network (VPN) enables remote offices or users to gain
secure access to their organization's network over the public telecommunications network.
This provides the benefits of remote access without the expense of dedicated leased or
owned lines. VPNs work by using tunneling protocols, such as L2TP, to encrypt data at the
sending end, and decrypt the data at the receiving end. This "tunnel" cannot be accessed
by data that is not properly encrypted.
