What is 4G ?

Two 4G candidate systems are commercially deployed:

the Mobile WiMAX (in South Korea in 2006),

the Long Term Evolution (in Sweden since 2009).

In the United States, Sprint has deployed Mobile

WiMAX networks, and MetroPCS was the first

operator to offer LTE service.

WiMAX smartphones have been available since 2010, and

LTE smartphones since 2011.

LTE and WiMAX, both of which are IP based networks , yet

they are incompatible technologies.

The WiMAX (Worldwide Interoperability for Microwave Access)

standard offers peak data rates of 128 Mbit/s downlink and

56 Mbit/s uplink over wide channels .

In June 2006, the world's first commercial mobile WiMAX

service was opened in South Korea.

WiMAX is a wireless technology put forth by the WiMAX

Forum that is one of the technologies that is being used for 4G

networks.

It can be used in both point to point and the typical WAN type

configurations that are also used by 2G and 3G mobile

network carriers.

Peak download 128 Mbit/s

Peak upload 56 Mbit/s

The bandwidth and range of

WiMAX make it suitable for the

following potential applications:

Providing portable mobile

broadband connectivity across

cities and countries through a

variety of devices.

Providing VoIP services.

LTE is not a replacement for UMTS in the way that UMTS was a

replacement for GSM, but rather an update to the UMTS technology that

will enable it to provide significantly faster data rates for both uploading

and downloading.

The goal of LTE was to increase the capacity and speed of wireless data

networks using new DSP (digital signal processing) techniques and

modulations.

The LTE standard supports only packet switching with its all-IP network

The basic difference between 3G and 4G is in data transfer and

signal quality where high quality videos can be streamed in just

seconds.

Verizon Wireless was the first U.S. carrier to widely deploy LTE,

though MetroPCS and AT&T have also done so.

Bharti Airtel launched India's first 4G service, using LTE technology,

in Kolkata on April 10, 2012

Although marketed as a 4G wireless service, LTE does not satisfy

the technical requirements of the 3GPP consortium has made for a

4th gen network, and this sets platform for the generation of LTE-

Advanced specification.
