What is meant by 2G,3G,4G in phones and tablets?what is the uses of now i cant understand!?


Dear Friend,

0G, 1G, 2G, 3G, 4G, and by Year 5G refers to the various generations of Phone Communication Technology

0G refers to the Mobile Radio Systems, Sometimes retroactively to as Pre Cellular or Zero Generation This systems included the to Talk (PTT or manual).

For Walkie-Talkies (2 Way Radio Telephone)

1G to the First Generation of Wireless Technology, which used Radio Signals.

1G speeds vary between 56kbit/s, which means download speeds of 2.9KBytes/s to

2G refers to the Second Generation of Mobile Technology, which Digital Radio Signals.

2G Telecom Networks are commercially on the GSM CDMA standards, commonly on the GSM-CDMA 850 / 900 / 1800 / 1900 MHz

2G provide services such as SMS Picture Messages) MMS ( Multi Messages).

2G networks were mainly for voice services and data transmission, Data vary between 56 kbit/s up to 72

2.5G (GPRS). GPRS provide data rates 56 kbit/s up to 115 kbit/s, it can be used for SMS MMS services as well as Internet

2.75G (EDGE). EDGE provide data rates 200 kbit/s

3G refers to the Third of Mobile Telecommunications Technology, provides data transfer of at least 200 kbit/s to 1 Mbit/s to Mobile Modems(Dongles) in Laptop

3G finds application in wireless telephony (VoIP), mobile access, fixed wireless access, video calls and TV.

3G Radio Interface is called commonly operated on the HSDPA 900, 1900, 2100 MHz

The latest UMTS release, can provide peak data of upto 56 Mbit/s in the downlink in (28 Mbit/s in existing services) and 22 in the uplink.

Applications of 3G,

3G devices rise to applications not previously to mobile phone users. of the applications are:

Mobile TV

on demand

Video Conferencing

Location-based services

Global System (GPS)

4G refers to the Generation of Mobile Telecommunications which provides mobile Internet access,For example to with USB wireless modems, to to other mobile devices.

High-definition mobile TV,

3D television

Cloud Computing.

Two 4G systems are commercially deployed:

the WiMAX standard (at first in Korea in 2006) Long Evolution (LTE) standard (at in 2009).

Data speeds of

// Peak download 128 Mbit/s // upload 56 Mbit/s

LTE // Peak 100 Mbit/s // Peak upload 50

LTE Advanced // Peak download 1 // Peak upload 500 Mbit/s

5G to the 5th generation mobile networks or 5th wireless systems.

Samsung has successfully tested its 5G with 1 Gbps speed up to 10 Gbps) aims to provide by 2020.

In testing, the transfer for the “5G” network sent at 1.056 Gbps to a distance of up to 2

The major difference from a point of view between 4G 5G must be something else increased maximum throughput;

for lower battery consumption, outage probability (better high bit rates in larger of the coverage area, cheaper fees due to low infrastructure deployment or higher aggregate capacity for simultaneous users
