BlackBerry adalah sebaris peranti bimbit tanpa wayar yang dibangunkan syarikat Kanada Research In Motion (RIM). Sementara ia menyertakan aplikasi telefon pintar (buku alamat, kalendar, senarai untuk-dibuat, dsb.) dan juga kebolehan telefon pada model baharu, BlackBerry paling dikenali kerana kebolehannya menghantar dan menerima e-mel di mana sahaja ia mendapat rangkaian wayarles pengendali telefon bimbit tertentu. Ia memiliki bahagian 20.8% pasaran jualan telefon pintar sedunia, menjadikannya pelantar kedua paling popular selepas Symbian Nokia,[2] dan telefon pintar paling popular di kalangan pengguna perniagaan.[3]

The first BlackBerry device was introduced in 1999 as a two-way pager. In 2002, the more commonly known smartphone BlackBerry was released, which supports push e-mail, mobile telephone, text messaging, Internet faxing, Web browsing and other wireless information services. It is an example of a convergent device.

BlackBerry first made headway in the marketplace by concentrating on e-mail. 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.

Most current BlackBerry models have a built-in QWERTY keyboard, optimized for "thumbing", the use of only the thumbs to type, and there are also several models that include a standard cell phone keypad for typing, and two models that are full touch-screen devices with no physical keyboard. System navigation is primarily accomplished by a scroll ball, or "trackball" in the middle of the device, older devices used a track wheel on the side and newer devices like the Blackberry Bold 9700 or Curve 8520/8530 use a small pad for navigation "trackpad" instead of a trackball. Some models (currently, those manufactured for use with iDEN networks such as Nextel and Mike) also incorporate a Push-to-Talk (PTT) feature, similar to a two-way radio.

Modern GSM-based BlackBerry handhelds incorporate an ARM 7 or 9 processor, while older BlackBerry 950 and 957 handhelds used Intel 80386 processors. The latest GSM BlackBerry models (8100, 8300 and 8700 series) have an Intel PXA901 312 MHz processor, 64 MB flash memory and 16 MB SDRAM.[4] CDMA BlackBerry smartphones are based on Qualcomm MSM6x00 chipsets which also include the ARM 9-based processor and GSM 900/1800 roaming (as the case with the 8830 and 9500) and include up to 256MB flash memory.[5][6]

Operating system[sunting | sunting sumber]

Rencana utama: BlackBerry OS
BlackBerry 7250

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 (1999–2006) or more recently the trackball (September 12 2006–present) and trackpad (September 2009-present). The OS provides support for Java 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.

At present, there are few (if any) reports of Blackberry devices being infected by computer viruses; the heavily-encrypted nature of Blackberry data transmission would seem to have prevented virus propagation thus far.

CPU[sunting | sunting sumber]

Early BlackBerry devices used Intel-80386-based processors.[7] The latest BlackBerry 9000 series is equipped with Intel XScale 624 MHz CPU,which makes the fastest BlackBerry to date. Earlier BlackBerry 8000 series smartphones, such as the 8700 and the Pearl, are based on the 312 MHz ARM XScale ARMv5TE PXA900. An exception to this is the BlackBerry 8707 which is based on the 80 MHz Qualcomm 3250 chipset; this was due to the ARM XScale ARMv5TE PXA900 chipset not supporting 3G networks. The 80 MHz 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.

Database[sunting | sunting sumber]

Data extracted from a BlackBerry to a host computer is stored in a single file in a BlackBerry-specific format known as IPD.[8] The file is encrypted (as are all transmissions through the Blackberry system), though since all Blackberry devices are capable of reading the IPD file format, more than one Blackberry can read the same database file.

Included in the standard Blackberry software package is a 'Switch Device Wizard' that permits a user to connect two mobile devices and copy the database from one device to another, enabling a newly-upgraded device to retain any personal information that is not device-specific.

Supporting software[sunting | sunting sumber]

BlackBerry Enterprise Server[sunting | sunting sumber]

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. Google has made a Connector for BES which makes BES available for Google Apps as well. 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 an 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 or on a polling basis. Blackberry also supports polling email, which is how it supports POP. 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 - Connection Service" (MDS-CS). This allows for custom application development using data streams on BlackBerry devices based on the Sun Microsystems Java ME platform.

In addition, BES provides network 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.

BlackBerry Internet Service[sunting | sunting sumber]

The primary alternative to using BlackBerry Enterprise Server is to use the BlackBerry Internet Service. It was developed primarily for the average consumer rather than for the business consumer. This service allows POP3 and IMAP email integration for the personal user. It allows up to 10 email accounts to be accessed, including many popular email accounts such as Gmail, Hotmail, Yahoo and AOL. There are also special bundles for just Myspace, Facebook, & MSN as well.

BlackBerry Desktop Redirector[sunting | sunting sumber]

A less common alternate to using BlackBerry Enterprise Server is to use the BlackBerry Desktop Redirector. This software is installed on a desktop computer that has the Enterprise email client installed.

Supported Software[sunting | sunting sumber]

BlackBerry Messenger[sunting | sunting sumber]

Newer BlackBerry devices use the proprietary Blackberry Messenger, also known as BBM, software for sending and receiving text messages via Blackberry PIN or barcode scan. There is also the BlackBerry Alliance program of partners who work under contract with Research In Motion to innovate new applications to differentiate the BlackBerry solution. Typical applications include digital dictation, GPS tracking, CRM and expense management. On October 6, 2009 Blackberry Messenger 5.0 was officially released, adding a whole new set of features, including bar code scanning to add contacts, profiles, sharing your location via GPS, and creating groups.

Third-party software available for use on BlackBerry devices includes full-featured 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.[9]
