Synchronization & Data Transfer
In everyday life, access to an updated calendar and details of friends and business colleagues is
greatly appreciated. To be truly mobile, users must be able to carry their important information
with them. Equipping mobile phones with Personal Information Manager (PIM) programs like
calendars, task lists and address books gives users access to their most important data
anywhere and anytime. The information is kept updated by synchronizing with the information at
the office or at home. The growing use of groupware such as Microsoft
®
Outlook
®
and Lotus
®
Notes
®
means that more and more meetings are booked electronically in daily business life.
The P800 uses the SyncML protocol for synchronisation. This means that it has compatibility to
synchronise with a wide variety of devices over a number of different communications media.
SyncML – An Open Standard for Synchronisation
SyncML Background
Leading the way in providing remote synchronization capability, Sony Ericsson realizes that
interoperability of remote synchronization is of utmost importance if mobile data usage is to
become as widespread as generally predicted. That is why Ericsson, along with IBM, Lotus,
Motorola, Matsushita, Nokia, Palm Inc., Psion and Starfish Software, founded the SyncML
initiative in February 2000. Supported by more than 600 software and hardware developers, the
SyncML initiative seeks to develop and promote a globally open standard for remote
synchronization, called SyncML. Unlike many other synchronization platforms, SyncML is an
open industry specification that offers universal interoperability. Because it uses a common
language, called XML, for specifying the messages that synchronize devices and applications,
SyncML has been called the only truly future-proof platform for enabling reliable and immediate
update of data. The benefit for the end user is that SyncML can be used almost anywhere and in
a wide variety of devices, regardless of application or operating system
What is SyncML?
SyncML is the common language for synchronizing all devices and applications over any
network. SyncML leverages Extensible Markup Language (XML), making SyncML a truly future-
proof platform. With SyncML any personal information, such as E-Mail, calendars, task lists,
contact information and other relevant data, will be consistent, accessible and up to date, no
matter where the information is stored. For example, a calendar entry made to a mobile device on
a business trip is equally available to a secretary in a network calendar. SyncML is the ultimate
choice for remote synchronization.
The P800 uses SyncML for both local synchronization (for example, with a PC using Bluetooth or
a cable connection) and remote synchronisation over HTTP.
Designed for the requirements of the wireless world
SyncML is designed specifically with the wireless world’s tight requirements in mind. SyncML
minimizes the use of bandwidth and can deal with the special challenges of wireless
synchronization, such as relatively low connection reliability and high network latency. SyncML
supports synchronization over WAP, HTTP or OBEX. As an open, future-proof standard, SyncML
is the synchronization choice for any device or application of the mobile information society. For
