allowing objects such as vCard contact information and vCalendar
schedule entries to be exchanged using either IrDA (IrOBEX) or
Bluetooth. Symbian OS implements IrOBEX for exchange of vCards,
for example between a Nokia 9210 Communicator and an Ericsson
R380 Smartphone, and vCalendar. |
|
OS |
Operating System: historically, the minimal set
of software needed to manage a device's hardware capability and
share it between application programs. Practically, "OS" is now
used to mean all software including kernel, device drivers,
comms, graphics, data management, GUI framework, system shell
application, and utility applications. This would define
Windows, Palm OS and MacOS as operating systems. Symbian
provides an operating system – Symbian OS – tailored for
data-enabled mobile phones. |
|
OPL |

walkie-talkie. This is a half-duplex voice over IP (VoIP)
solution using the existing GPRS and EDGE data networks that are
part of current GSM systems. |
|
Packet-switching |
Technique whereby the information (voice or data)
to be sent is broken up into packets, of at most a few KB each,
which are then routed by the network between different
destinations based on addressing data within each packet. Use of
network resources is optimized, as the resources are needed only
during the handling of each packet. This is an ideal model for
ad hoc data communication, and works well also for voice, video
and other streamed data. Mobile phones with packet-switched
communication appear to be "always connected" to the data
network, whereas in the case of circuit-switched connections,
setup time takes around 30 seconds to connect from a mobile
phone to an ISP. Use of packet-switched network can be charged
according to the volume of data transferred and not to any
notion of time spent online. |
