How wireless connectivity BlackBerry
Server BlackBerry institutions
Is used Blackberry inside e-mail system of the institution through a software system
called server BlackBerry institutions PES (BES), where there are plenty of copies BES
that can be used with Microsoft systems Xsthang Server and Lotus Domino and Novell
Groboayz, as Google has designed interface enables users from using BES in Google Apps
While individual users may be able to use the e-mail service provided by wireless
Internet service provider without the need to prepare the BES itself, but the
institutions usually running BES on their own network, as some companies offer free
hosting solutions BES servers. Per BlackBerry has its own identification number called
a PIN, which is used to identify the device for BES. It is worth mentioning that it is
possible to use the free version of BES called BES Express.
BES works as a carrier for e-mail to e-mail accounts institutions so that users can
access their messages as soon as they arrive. Monitors program local users, and when a
new message comes, it picks up the message and passes it to the Network Operations
Center (NOC) company RIM. And then re-send the message to the user wireless provider,
which in turn lead them to a user's BlackBerry device.
Known technology transfer e-mail to pay e-mail, because all new e-mails, contacts,
calendar entries, tasks and entries internal memos are to be paid to the BlackBerry
device automatically and instantly (unlike the user synchronizes data manually or on
the basis of ballot e-mail servers at intervals). Supports BlackBerry e-mail ballot,
too, which is the method used by the support POP. The BlackBerry device stores the
contents of the e-mail on the hard disk, which can be used to access the contents of
the mail in areas where there are no wireless services. Once the user connects again,
the BES update the data on the device.
Included in the new models of the Blackberry the ability to track the current location
of the device through trilateration without the need to use global positioning system,
which increases the effectiveness of the battery. However, the accuracy of
trilateration BlackBerry are less than those of the Global Positioning System and it is
due to a number of factors, such as withholding send cell tower because of the huge
buildings, Oaljebal, or distance.
This allows the development of custom applications using the data stream on BlackBerry
devices based on the Java platform or any offered by Sun Microsystems.
In addition, it provides BES network security in the form of Triple DES, and more
recently, encryption AES (AES) to encrypt all data (both e-mail and the progress of
MDS) that travels between mobile BlackBerry and server BlackBerry institutions.
Most service providers shows Blackberry fixed monthly pricing to transfer an unlimited
amount of data between BlackBerry devices and BES. Institutions can, in addition to
receiving e-mail, be designed intranets or custom internal applications using follow-up
amounts of data transfer rate.
With recent versions of BlackBerry devices, there is no need to use MDS component to
access data wirelessly. The beginning of the operating system 4.0, can for BlackBerry
devices to access the Internet (ie, packet protocols access Internet (TCP / IP))
without MDS where it was not possible to access only to e-mail and wireless application
system without BES / MDS previously. Still the BES / MDS is required in order to get an
e-mail, applications, secure data and require the use of WAP mobile phone companies
that do not provide WAP service.
BlackBerry Internet Service
The main alternative to a corporate BlackBerry server is BlackBerry Internet Service.
Blackberry Internet service is available in 91 countries around the world, where it was
developed to use the average consumer rather than a businessman. BlackBerry Internet
Service allows integration with IMAP and POP3 technology and up to ten e-mail accounts
include popular Internet services such as Gmail, Hotmail and Yahoo. BlackBerry Internet
Service allows also using the capabilities of "payment" available in many applications
designed by a company BlackBerry applications such as Instant Messaging and social
networking applications (Facebook, Twitter, MySpace).
