Mobile Network generation -1G,2G,3G,4G,5G Explain

mobile network genereation | Network within telecommunication is a terminal code collection. This link is linked to telecommunication and telecommunications enabled telecommunications links. Nodes are used to pass the signal through circuit switching, message switching or packet switches right link.


Mobile Network generation -1G,2G,3G,4G,5G Explain




Cellular networks offer a number of desirable features:

  1. More capacity than a single large transmitter, since the same frequency can be used for multiple links as long as they are in different cells
  2. Mobile devices use less power than with a single transmitter or satellite since the cell towers are closer
  3. Larger coverage area than a single terrestrial transmitter, since additional cell towers can be added indefinitely and are not limited by the horizon

     type of mobile network generation

  •  first generation / 1G
  •  second generasion / 2G
  •  third generasion /3G
  •  fourth generasion /4G

first generation / 1G

1G  refers to the first generation of wireless telephone technology, mobile telecommunications which was first introduced in 1980s and completed in early 1990s.

     1G FEATURES
  1. It allows the voice calls in 1 country.
  2. AMPS  (Advanced Mobile Phone System was)
  3. First launched in USA in 1G mobile
  4. 1G network use  Analog Signal.
     problems with 1G
  1.  Poor Battery Life
  2.  Large Phone Size
  3.  No Security
  4.  Limited Capacity
  5.  Poor Handoff Reliability 
  6.  Poor Voice Quality

second generasion / 2G

2G (GSM, CDMA), first came in 1992, 2G network was second generation of cellular telephone technology, and the first digital encryption conversion network was created.

The 2G network was the first network to offer offers such as data service and SMS text messaging for the first time, but their data transfer rates are less than those of their successors.

2.5G networks (GPRS, CDMA2000 1x) is 2G modifiers, with theoretical data rates up to 144kbit / s GPRS is the first always-on data service
2G technology refers to the 2nd generation which is based on GSM.
It was launched in Finland in the year 1991.
2G network use digital signals
It's data speed upto 64kbps.

2G Features :

  1. Enables services such as text messages
  2. picture messages and MMS (multi media message).
  3. It provides better quality and capacity
  problems with 2G

  1. 2G requires strong digital signal to help mobile phones work. If there is no network coverage in any specific area , digital signals would  weak.
  2. These systems are unable to handle complex  data  such as Video.

third generasion /3G



3G (UMTS TDD / TD WCDMA), networks successful 2G ones, offers fast data and the first network that has enabled video calling.



This makes them very suitable for use in modern smartphones, which requires constant high-speed internet connection for many of their applications



Note-basics of UMTS TDD, the time division duplex cellular technology sometimes called TD WCDMA, part of the UMTS 3G system.

 3G technology which was introduced in the year 2000s

 Data Transmission speed increased from 144kbps- 2Mbps

 Typically called Smart Phones and features increased its bandwidth and data transfer rates to accommodate

web-based applications and audio and video files

  7. This makes them very suitable for use in modern smartphones, which requires constant high-speed internet connection for many of their applications
Problem with 3G

  1. Expensive fees for 3G Licenses Service
  2. It was challenge to build the infrastructure for 3G
  3. High Bandwidth Requirement
  4. Expensive  3G Phones.
  5. Large Cell Phones

fourth generasion/ 4G


4G (LTE), this is the fourth generation of mobile phone communication. It is a successor of the 3G and provides ultra-broadband internet access for mobile devices. The high data transfer rates make 4G networks are suitable for use in USB wireless modems for laptops and even home internet access
4G technology, which was launched from late 2000s.
Capable of providing 100Mbps - 1Gbps speed
One of the basic term used to describe 4G is MAGIC.
Mobile Multimedia Anytime Anywhere
Global Mobility Support
Integrated Wireless Solution
Customized Personal Services
Also known as Mobile Broadband Everywhere.


features of 4G

  1. The next generations of wireless technology that promises  higher data rates and expanded multimedia services.
  2.  Capable to provide speed 100Mbps-1Gbps.
  3.  High QOS and High Security
  4.  Provide any kind of service at any time as per user requirements, anywhere.


problem of 4G



  1.   Battery uses is more Hard to implement
  2.   Need complicated hardware
  3.   Expensive equipment  required to implement next generation network.
