Introducction
Analog telephones are considered the first generation ofmobile phone technology (1G), digital cellular phones,second generation (2G) digital devices and high-speed
broadband are the third generation (3G).
The 4G will be based entirely on IP being a system ofsystems and a network of networks, reaching after theconvergence of wired and wireless networks as well as
computers, electrical and information technology as well asother convergences to provide access speeds between 100Mbps and 1 Gbps in motion at rest, maintaining a quality ofservice (QoS) from end to end (end-to-end) to enablehighly secure offer of any kind at any time, anywhere , at
the lowest cost possible.

PAST, PRESENT AND FUTURE OF
TELECOMMUNICATIONS
1G: Analog cellular network =Circuit Switched
2G: digital cellular network
(GSM) = Circuit Switched 2.5G: digital cellular network
(GPRS) = Packet Switching
3G Network UMTS = cellulardigital packet switching
4G: Digital Cellular networkmedia = all-IP (VoIP)

Description
The WWRF (Wireless World Research Forum) defines4G as a network operating in the Internettechnology, combining it with other applications andtechnologies such as Wi-Fi and WiMAX.
The 4G technology is not a standard or defined, but acollection of technologies and protocols to allow
maximum throughput with the cheapest wirelessnetwork. The IEEE has not yet spoken to the 4Gdesignating as "beyond 3G".

Description
In Japan it is already experimenting with fourth
generation technologies, NTT DoCoMo being at the
forefront.
This company made the first tests with flying colors
(reached 100 Mbps to 200 km / h) and expects to
commercially launch the first 4G services in 2010. In
the rest of the world is expected to implement over
2020.

Conclusions
Given the current situation of the cell, itsimprovement is needed, ie no point in having to usea single device to talk, if you can have the same
device for endless activities at the touch of abutton.
Currently in Mexico's 3G technology brings about a
year and is discovering just what we can do withthis type of cell, a clear example is to watch TV inreal time.

Given the rapid advance of technology, it is very likelythat we will see the 4G, surely we can not see it as soonuntil research and development expenses incurred for the3G are profitable, therefore, although the 4G is already
just around the corner, we will have to wait at least acouple of years.
It will soon have to take advantage of 3G wheretransmissions are not as fast as the 4G but still bring
things that could be expected only in science fiction, whoknows maybe soon we can control the work from homeor cell .
