GENERATIONS
OF MOBILE DEVICE
Mobile device
has been passed into different generation due to the development of technology
of transfer data, voice and messages. Mobile have been used as a major device
that facilitate communication.
Generation of
mobile refers to the different generations of mobile device
It include
·
0G- zero generation
·
1G-first generation
·
2G-second generation
·
3G-third generation
·
4G-fourth generation
0G- ZERO GENERATION (1946-1980)
In zero generation
the mobile phone was only use for transfer voice
In zero
generation there are early mobile phones that is very expensive in that time
and its mostly kept in cars, trucks and briefcase
1G-FIRST GENERATION (1980s-now)
First generation comes with the cellular phones network for radio signals
(Analogy). The technology developed for AMPS/Data Tac
In this generation it composed of voice and limited data and the first
blackberry (850) was developed.
2G-SECOND
GENERATION (1990s-now)
The second
generation cellular networks dominate with Digital data, SMS and Circuit
switched data.
Technology
developed GSM, iDEN,CDMA and TDMA
2.5 GENERATION
2.5G is the
update of the 2G generation where technology based on marketing terms. The
technology developed is GPRS, WiDEN, HSCSD,
EDGE, CDMA2000 and 1x-RTT
GSM- GLOBAL
SYSTEM FOR MOBILE COMMUNICATION
GSM (Global System for Mobile communication) is a digital mobile telephony system that is widely used in Europe and other parts of the world. GSM uses a variation of time division multiple access (TDMA) and is the most widely used of the three digital wireless telephony technologies
GPRS- GENERAL
PACKET RADIO SERVICE
General Packet
Radio Service is a packet-switching technology that enables data transfers
through cellular networks. It is used for mobile internet, MMS and other data
communications. In theory the speed limit of GPRS is 115 kbps, but in most
networks it is around 35 kbps. Informally, GPRS is also called 2.5G.
iDEN-
INTERGRATED DIGITAL ENHANCED NETWORK
iDEN (Integrated Digital Enhanced Network) is a wireless technology from Motorola combining the capabilities of a digital cellular telephone, two-way radio, alphanumeric pager and data/fax modem in a single network.
CDMA-CODE
DIVISION MULTIPLE ACCESS
CDMA (Code-Division Multiple Access) refers to any
of several protocols used in so-called second-generation (2G) and
third-generation (3G) wireless communications
CDMA is a form
of multiplexing, which allows numerous signals to occupy a single transmission channel,
optimizing the use of available bandwidth
3G-THIRD GENERATION
(2004-now)
Third generation
of the cellular networks comes with broadband data, voice and streaming video.
wireless network
technologies must be able to provide a mobile device with a downlink connection
speed of 384kbps in order to be considered a 3G technology.
Technology used W-CDMA
(UMTS, FOMA), 1xEV-DO
4G-FOURTH
GENERATION(THE FUTURE)
This generation
is still on progress and target with high-speed broadband for data and
visual-centric information
Transmit of data
at 100mbps while moving and 1GB while standing still
