A Wireless and Mobile VPN Solution The Black Box
Harleen Serai, Supervisor - Brian Lovell
What is the Black Box? In todays rapidly
changing business environment, obtaining
information is simply not enough timing is
critical. It is even more pertinent for companies
with a mobile workforce. The black box is the
first solution in Australia that can provide
prompt information services to and from mobile
staff irrespective of their location. How does
it work? As shown in the figure (right), the
black box uses GPRS to communicate with the
company network and Bluetooth to communicate with
the mobile staff PDAs.

• Scope of Thesis - The Black Box/PDA Bluetooth
  Modules
• What is achieved?
• Bluetooth access from Microsoft .NET.
• Multiple Bluetooth connections between devices.
• Automatic connection handling as devices come in
  and out of range.
• Event based transfer of files and strings
  between user applications.
• How does it work? The figure on the left shows
  the architecture of the Module. Bluetooth
  communication between devices is achieved through
  the L2CAP layer API to allow for multiple
  connections. The purpose of the .NET wrapper is
  to achieve Bluetooth visibility from .NET. It
  also allows multiple user applications to access
  the Bluetooth from .NET.
• How can it be used? This module can be used by
  developers to write custom Bluetooth applications
  in .NET for the Black Box and the PDA.
