Evolution From 1G to 4G

First Generation [1G] 1G refers to the first-generation of

wireless telephone technology was developed in 1970’s.

1G had two major improvements: the invention of the

microprocessor the digital transform of the control

link between the phone and the cell site.

Analog signal

Second Generation [2G] Around 1980’s Better quality & capacity –

More people could use there phones at the same time

Digital Signals – consist of 0’s & 1’s

The digital voice encoding allows digital error checking increase sound quality lowers the noise level

Going all-digital allowed for the introduction of digital data transfer SMS –“short message service” E-mail

Advantages of 2G

Disadvantages of 2G

Cell towers had a limited coverage area Jagged Decay curve• Abrupt dropped calls• Analog –gradual sound reduction

“Spotty” coverage

Third Generation [3G] Large capacity and broadband capabilities

Allows the transmission of 384kbps for mobile systems and up to 2Mbps

Increased spectrum efficiency –5Mhz A greater number of users that can be

simultaneously supported by a radio frequency bandwidth

High data rates at lower incremental cost than 2G–Global roaming

High input fees for the 3G service licenses Inefficient to meet needs of future high-

performance Multiple standards for 3G Require wider bandwidth Lack of coverage because it is still new

service

4G combines following :- Faster and more reliable 100 Mb/s Lower cost than previous generations Multi-standard wireless system Bluetooth, Wired, Wireless Ad Hoc Networking IPv6 Core OFDM used instead of CDMA Potentially IEEE standard 802.11n Most information is proprietary

4G Hardware Ultra Wide Band Networks :Ultra

Wideband technology, or UWB, is an advanced transmission technology that can be used in the implementation of a 4G network.

Smart Antennas :: Multiple “smart antennas” can be employed to help find, tune, and turn up signal information

4G in IndiaBharti Airtel launched India's first 4G service,using TD-LTE technology, in Kolkata on April 10, 2012. Airtel 4G services are available in Kolkata, Delhi, Bangalore, Pune and Chandigarh RIL is launching 4G services through its subsidiary, Jio Infocomm. RIL 4G services are currently available only in Jamnagar.
