Jyothisha A R, Anina Thomas

ABSTRACT: 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.

A Blackberry technology 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 end-to- end wireless email solution that allows access to you Outlook inbox, calendar, contacts and Tasks with full wireless synchronization.

The process works in reverse when you make changes on your Blackberry device that need to be copied into your Outlook account, example: if you send a message that needs to be copied to your contacts list. The original Blackberry device had a monochrome display, but all current models have colour display.

Most Blackberry are Bluetooth capable, allowing for the use of wireless Bluetooth headsets to handle telephone calls. Becausethe BlackBerry relies on the cellular telephone network, it is only available through cell phone carrier, like cell phones, each carrier has its own unique models.

INTRODUCTION

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 Rims 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 Microsystem 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.

What is Blackberry Technology?

The recent Blackberry 9000 series has been designed and work on the Intel Xscale 624MHzCPU. The earlier version of Blackberry cell phones worked with an 80MHz processor and were hence comparatively slower in downloading 3G web pages. Blackberry uses an IPD file for its data storage. A single IPD is used The recent Blackberry 9000 series has been designed and work on the Intel Xscale 624MHz for the database handling which makes the performance even faster.The technology encompasses simple features like calendar, reminders and games, along with the basic applications of making and receiving calls and messages. Besides the basic features it also allows you to send emails and browse web pages.

The manufacturers have also tied up with various vendors like Microsoft, IBM and Novell to integrate Outlook, Notes and Groupwise into these phones. Almost all the phones manufactured with the Blackberry technology have Bluetooth integrated in them. Some models also have inbuilt cellular feature. History The Blackberry was a communication device that was developed in a Canada based company, Research in Motion (RIM) in 1999. It was built in with a multi-tasking operating system. The earlier phones manufactured under this technology used the 80386 microprocessor for their working.

How it works

As we all know, there is always software behind the hardware. This holds true for the blackberry as well. Blackberry Server Software comes in two forms

  1. BlackBerry Professional Software (BPS)

  2. Message arrives at your email server (usually the exchange server) and is sent as normal to your PC/ Laptop (as in fig 3.1).

  3. The BlackBerry server (the mail is delivered using a "push" concept to the Blackberry Enterprise Server) compresses, encrypts and forwards the message automatically to your BlackBerry handset.

  4. Message arrives at the BlackBerry via the Internet and the mobile carrier's network.

  5. The Blackberry handheld device receives decrypts and decompresses the email, and alerts the user.

It's designed for medium to large organizations with their own Lotus Domino or Microsoft Exchange servers for email and mobile data applications, that are going to start with at least 20 users and grow from there.

    Blackberry Enterprise Server lets the user access his/her email, electronic calendar, tasks list and contacts list as well as any internal applications or software on their BlackBerry handheld.

    The Blackberry Enterprise Server supports triple DES security (considered unbreakable) so confidential data is transmitted securely.
