The BlackBerry is a wireless handheld device introduced in 1997 as
a two-way pager. The more commonly known smartphone BlackBerry, which
supports push e-mail, mobile telephone, text messaging, internet faxing, web
browsing and other wireless information services was released in 2002. It is an
example of a convergent device. Developed by the Canadian company Research In
Motion (RIM), it delivers information over the wireless data networks of mobile
phone service companies. BlackBerry first made headway in the marketplace by
concentrating on e-mail. RIM currently offers BlackBerry e-mail service to nonBlackBerry
devices, such as the Palm Treo, through the BlackBerry Connect
software. The original BlackBerry device had a monochrome display, but all
current models have color displays.
While including PDA applications (address book, calendar, to-do
lists, etc.) as well as telephone capabilities on newer models, the BlackBerry is
primarily known for its ability to send and receive e-mail wherever it can access a
wireless network of certain cellular phone carriers. It has a built-in keyboard,
optimized for "thumbing", the use of only the thumbs to type. System navigation is
primarily accomplished by a scroll ball in the middle of the device (older devices
used a track wheel on the side). BlackBerry users can generally be divided into two
camps: consumers who bought and own their BlackBerry, and enterprise end-users
who are given the use of a BlackBerry by their employers. Consumer devices are
generally configured to use BlackBerry Internet Service (BIS), while enterprise
devices are generally configured to use BlackBerry Enterprise Server (BES). In a
BIS environment, the end-user is generally responsible for the appropriate
configuration of security measures. In a BES environment, the end-user has a
certain amount of control, but security is usually enforced by the enterprise, via the
use of an IT Policy and Application Controls. More comprehensive controls are
available in a BES deployment than in a BIS deployment
INTRODUCTION
A Blackberry is a personal communications device developed, distributed, and serviced
by Research in Motion(RIM), a Canadian company headquartered in Waterloo, OntarioA
.Blackberry can provide email, text messaging, web browsing, and telephone service. It is an
example of a convergent device
A BlackBerry is an end-to-end wireless email solution that allows access to your Outlook
Inbox, Calendar, Contacts, and Tasks with full wireless synchronization. The BlackBerry Server
constantly communicates with the campus Exchange server (that talks to Outlook, among other
email clients).As soon as something comes into your Outlook for Exchange email, the
BlackBerry server gets a copy and sends it to your device through the Internet. Your device
receives that information through the Internet using your carrier's preferred network.The process
works in reverse when you make changes on your BlackBerry device that need to be copied into
your Outlook account, e.g., if you send a message that needs to be copied to your Sent items, or
if you add a contact to your Contacts list. The Blackberry can be set up and operated wirelessly
without ever being connected physically to a computer. RIM currently offers BlackBerry e-mail
service to non-BlackBerry devices, such as the Palm Treo, through the BlackBerry Connect
software. The original BlackBerry device had a monochrome display, but all current models
have color displays
Research in Motion provides the native email system for the Blackberry. However, RIM
has cooperated with Microsoft, IBM, and Novell to provide full two-way email integration with
Outlook, Notes, and GroupWise ,respectively Standard features on a Blackberry include
calendar, tasks, notes, alarm clock, calculator, and some games. Third party applications can be
downloaded to extend its capability. Some models available from Nextel, Sprint, and maybe
other carriers, provide GPS and cellular “walkie-talkie” service as well. Most Blackberry are
Bluetooth capable, allowing for the use of wireless Bluetooth headsets to handle telephone calls.
Because the Blackberry relies on the cellular telephone network, it is only available through cell
phone carriers .And, like cell phones, each carrier has its own unique models. The typical cost of
a Blackberry is $250-$300,

Operating system:
RIM provides a proprietary multi-tasking operating system (OS) for the BlackBerry,
which makes heavy use of the device's specialized input devices, particularly the scroll wheel
(1995 - 2006) or more recently the trackball (September 12th 2006 - Present). The OS provides
support for MIDP 1.0 and WAP 1.2. Previous versions allowed wireless synchronization with
Microsoft Exchange Server's e-mail and calendar, as well as with Lotus Domino's e-mail. The
current OS 4 provides a subset of MIDP 2.0, and allows complete wireless activation and
synchronization with Exchange's e-mail, calendar, tasks, notes and contacts, and adds support for
Novell GroupWise and Lotus Notes.
Third-party developers can write software using these APIs, and proprietary BlackBerry
APIs as well, but any application that makes use of certain restricted functionality must be
digitally signed so that it can be associated to a developer account at RIM. This signing
procedure guarantees the authorship of an application, but does not guarantee the quality or
security of the code.
2.2 CPU:
Early BlackBerry devices used Intel-80386-based processors.[6] Later BlackBerry
8000 series smart phones, such as the 8700 and the Pearl, are based on the 312MHz ARM X
Scale ARMv5TE PXA900. An exception to this is the BlackBerry 8707 which is based on the
80MHz Qualcomm® 3250 chipset, this was due to the ARM X Scale ARMv5TE PXA900
chipset not supporting 3G networks. The 80MHz Processor in the BlackBerry 8707 actually
meant the device was often slower to download and render web pages over 3G than the 8700 was
over EDGE networks.
Supporting software:
BlackBerry handhelds are integrated into an organization's e-mail system through a
software package called " BlackBerry Enterprise Server" (BES). Versions of BES are available
for Microsoft Exchange, Lotus Domino and Novell GroupWise. While individual users may be
able to use a wireless provider's e-mail services without having to install BES themselves,
organizations with multiple users usually run BES on their own network. Some third-party
companies provide hosted BES solutions. Every BlackBerry has a unique id called BlackBerry
PIN which is used to identify the device to the BES.
BES can act as a sort of e-mail relay for corporate accounts so that users always
have access to their e-mail. The software monitors the user's local "inbox", and when a new
message comes in, it picks up the message and passes it to RIM's Network Operations Center
(NOC). The messages are then relayed to the user's wireless provider, which in turn delivers
them to the user's BlackBerry device.This is called "push e-mail," because all new e-mails,
contacts and calendar entries are "pushed" out to the BlackBerry device automatically, as
opposed to the user synchronizing the data by hand. Device storage also enables the mobile user
to access all data offline in areas without wireless service. As soon as the user connects again,
the BES sends the latest data.
An included feature in the newer models of the BlackBerry is the ability for it to
track your current location through Trilateration. One can view the online maps on the phone and
see current location denoted by a flashing dot. However, accuracy of BlackBerry trilateration is
less than that of GPS due to a number of factors, including cell tower blockage by large
buildings, mountains, or distance.
BES also provides handhelds with TCP/IP connectivity accessed through a
component called "Mobile Data Service" (MDS). This allows for custom application
development using data streams on BlackBerry devices based on the Sun Microsystems Java ME
platform.
In addition, BES provides security, in the form of Triple DES or, more recently, AES encryption
of all data (both e-mail and MDS traffic) that travels between the BlackBerry handheld and a
BlackBerry Enterprise Server.
Most providers offer flat monthly pricing for unlimited data between BlackBerry units and BES.
In addition to receiving e-mail, organizations can make intranets or custom internal applications
with unmetered traffic.
With more recent versions of the BlackBerry platform, the MDS is no longer a
requirement for wireless data access. Beginning with OS 3.8 or 4.0, BlackBerry handhelds can
access the Internet (i.e. TCP/IP access) without an MDS - previously only e-mail and WAP
access was possible without a BES/MDS. The BES/MDS is still required for secure e-mail, data
access, and applications that require WAP from carriers that do not allow WAP access.
Newer BlackBerry devices use the proprietary Blackberry Messenger software for
sending and receiving text messages via Blackberry PIN.
Third-party software available for use on BlackBerry devices includes fullfeatured
database management systems which can be used to support customer relationship
management clients and other applications that must manage large volumes of potentially
complex data.
2.5 BlackBerry PIN:
BlackBerry PIN is an eight character hexadecimal unique identification
number assigned to each BlackBerry device. PINs cannot be exchanged and are locked to each
handset device. BlackBerrys can message each other using the PIN number directly or by using
the Blackberry Messenger application.
