pocketable mobile computers, netbooks, tablets, mediaphones, connected TVs and invehicle
infotainment systems.
Mobile device:
A generic term for devices that are used for mobile communications over a cellular
network.
Mobile phone:
A generic term for mobile devices that are based on nonprogrammable software
platforms. Mobile phones can run applications such as email and web browsing, and can also have
builtin music players, video recorders, mobile TV and other multimedia features. However, software
capabilities are generally less powerful in mobile phones than in converged mobile devices (See
Converged mobile device
).
Multiplexing:
A process of combining a number of signals so that they can share a common
transmission facility.
Multiradio:
Able to support several different radio access technologies.
NGOA (Next Generation Optical Access):
Future telecommunications system based on fiber optic
cables capable of achieving bandwidth data rates greater than 100 Mbps.
OFDM (Orthogonal FrequencyDivision Multiplexing):
A technique for transmitting large amounts
of digital data over a radio wave. OFDM works by splitting the radio signal into multiple smaller
subsignals that are then transmitted simultaneously at different frequencies to the receiver.
Open source:
Refers to a program in which the source code is available to the general public for
use and modification from its original design free of charge.
OS:
Operating System.
Packet:
Part of a message transmitted over a packet switched network.
Platform:
A basic system on which different applications can be developed. A platform consists of
physical hardware entities and basic software elements such as the software platform.
Series 30:
A software platform that powers Nokia’s most costeffective voice and messaging
phones.
Series 40:
A software platform that currently powers the majority of our mobile phone models and
supports different functionalities and applications, such as Internet connectivity.
Smartphone:
(See
Converged mobile device
).
Symbian:
A software platform which supports a wide array of functionalities, and provides
opportunities for the development of sophisticated applications and content by third parties. Our
smartphones are powered by Symbian.
TDLTE (time division long term evolution):
An alternative standard for LTE mobile broadband
networks
TDSCDMA (time division synchronous code division multiple access):
An alternative 3G
standard.
Transmission:
The action of conveying signals from one point to one or more other points.
VDSL (very high bit rate digital subscriber line):
A form of digital subscriber line similar to
asymmetric digital subscriber line (ADSL) but providing higher speeds at reduced lengths.
VoIP (Voice over Internet Protocol):
Use of the Internet protocol to carry and route twoway voice
communications.
Wavelengthdivision multiplexing:
Multiplexing in which several independent signals are allotted
separate wavelengths for transmission over a shared optical transmission medium.
