systems to provide mobile users with access to email
messages, instant messaging, and personal
management information tools

HTTP over the RIM ® IPPP
– Preprocesses and compresses HTML or XHTML
content before sending it to the BlackBerry smartphone,
which speeds up transfers
– Sends processed content to the BlackBerry smartphone
as it becomes available
– Optimizes images for display on BlackBerry smartphone

Mobile infrastructure and Internet connectivity
– BlackBerry Infrastructure supports communication with
BlackBerry smartphones over wireless networks through a
secure connection from behind a firewall.
– Internet connectivity is based on TCP/IP and the Open
Systems Interconnection model which defines Internet
working in vertical layers.
– OSI upper layers are Application, Presentation, and Session
for encryption and connection management.
– OSI lower layers are Transport, Network, Data Link, and
Physical for routing, addressing, and flow control.
