How the Blackberry Works

You as the blackberry user is provided with the physical wireless handheld device in a pager style or a palm style design. These devices both have an integral wireless modem which allows them to be connected over multiple telecom wireless networks. The BB itself is equipped with a version of their own sophisticated wireless protocol enabling the BB to connect with the similar blackberry message centers.

The BB is supported by the RIM operated BB message center. E-mails addressed to the mobile device directly are controlled by this message center using apprppriate internet protocols and then delivered to the BB device using the RIM wireless protocols. The modem remains on constantly to assure incoming messages are captured and the mobile BB then contacts the user as the new message arrives.

When sending a message, the BB user writes the message as they would an other e-mail and then sends it to the BBy message center with the aid of the RIM protocols. The message center then delivers the e-mail to the recipient using the normal internet e-mail protocols.

Many BB owners like their BB to perform as a wireless tool of an existing e-mail account. The user may opt to use their BB system function as a real time extension of their Microsoft Outlook mail program. At this point, the BB user would install the desktop redirector software on their pc in order to accept e-mail onto the BB.

When the BB user sends a message, the message center would send the message to its recepient as usual and it sends a message to the desktop redirector program to facilitate the mailbox sync between the BB and the desktop pc e-mail application. Another kind of sync is used for forwarding, deleted etc using the RIM protocols.

For integration into company e-mail systems, RIM provides the BB enterprise server which will integrate with the corporate MS exchange message center. This server acts in similar fashion as the desktop redirector talked about above with one difference, the sync action is at the message center rather than at the users desktop mail application. Themessages are delivered to the message center and then delivered to the BB.

Similar in operation with one difference. The company enterprise server functionss at a server level whereas the desktop redirector software operates on a desktop pc level.
