BlackBerry

This article is about the wireless e-mail device. For the fruit, see Blackberry. For other meanings, see blackberry (disambiguation).

BlackBerry 7100tThe BlackBerry is a handheld wireless device providing e-mail, telephone, text messaging and web browsing and other wireless data access.

Hardware

(1) Trackwheel, (2) Escape key and (3) radio/phone speaker on the BlackBerry 7510The devices are manufactured by the Canadian company Research In Motion (RIM) and are resold by cellular phone companies throughout the world. They fit in the palm of the hand and are operated using a scroll wheel and buttons. The original BlackBerry device had a monochrome display, but the newer models are colour.

While including the usual 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 anywhere it has access to an appropriate wireless network, as well as for its built-in keyboard optimized for "thumbing", or using only your thumbs to type. System navigation is primarily accomplished by the trackwheel (or "thumbwheel"), a scrolling wheel with a "click" function, located on the right side of the device. Some models (such as 7510 and 7520) also incorporate a two-way radio.

The devices are very popular with some businesses, where they are primarily used to provide e-mail delivery to roaming employees. To fully integrate the BlackBerry into a company, the installation of BlackBerry Enterprise Server (BES) is required.

In November 2004, RIM announced that the number of subscribers to the BlackBerry service had reached two million, having doubled within ten months.

Keyboard

Most BlackBerry devices come with a full QWERTY keyboard, using the "Alt" key to enter numbers and special characters. The new 7100 series models feature a combination standard number keypad and QWERTY combination, using an intuitive typing technology similar to T9.

Operating system

RIM provides a proprietary operating system (OS) for the BlackBerry, which makes heavy use of the device's specialized input devices, particularly the thumbwheel. 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.

Software can be written using these APIs, but needs to be signed by RIM first so that an application can be associated to a developer account at RIM. This signing procedure does not ensure the safety of the code.

Supporting software

BlackBerry handheld integration into an organization's e-mail system is provided through a software package called "BlackBerry Enterprise Server" (BES). Versions of BES are available for Microsoft Exchange, Lotus Domino and Novell Groupwise.

Individual users can often use e-mail services provided by the wireless provider and therefore may not be required to install a BES server on their local network, but organizations that have multiple wireless users usually run BES on their own network.

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 procedure, where the mobile user doesn't have to synchronize the data by hand. All new e-mails, contacts and calendar entries are pushed to the BlackBerry device automatically. This also enables the mobile user to access all data offline in areas without wireless service. As soon as he connects again, the BES sends the latest data. This way the handheld is always up-to-date.

BES also provides handhelds with TCP/IP connectivity that is proxyed 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 J2ME platform.

In addition, BES provides security, in the form of 3DES 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.

The universal connectivity of the BES/MDS infrastructure is one of the most valuable aspects of Research In Motion's product. An organization can have devices on different carriers, and connected through different cellular network protocols, all functioning in an integrated fashion.

Most providers offer flat monthly pricing for unlimited data between BlackBerry units and BES, which also enhances the value of the MDS component. 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 and data access.

Certain BlackBerry devices from Nextel and Telus have always had the ability to access the Internet without requiring a BES/MDS.

Third Party Software

Thanks to the MDS component, which allows secure data access between BlackBerry handhelds and the BES, a growing number of third party commercial applications are available for BlackBerry. These include applications in sales force automation, customer relationship management, and remote IT management.

Social usage

Thanks to their gains in popularity, BlackBerry devices are also used in social scenarios for setting up dates or movie viewing times with friends and acquaintances.

Nicknames

The ability to read e-mail that is received in realtime, anywhere, has made the BlackBerry devices infamously addictive, earning them the nickname "CrackBerry". Smaller blue-coloured models of the BlackBerry are colloquially nicknamed "BlueBerrys". Due to the abbreviated company name displayed prominently on early BlackBerry devices, they are mistakenly nicknamed "RIM".

Internal to the company, various model families are named for subatomic particles; names used include Proton, Baryon, Quark and Charm, among others.
