By Admin on

Firstly, when wireless generation started, it was analog communication. That generation is 1G. They used various analog modulation for data transfer. Now when the communication migrated from analog to digital, the foundation of latest communication were led. Hence came 2G.

1G Technology:

  • 1G refers to the first generation of wireless telephone technology, mobile telecommunications which was first introduced in 1980s and completed in early 1990s.
  • It’s Speed was upto 2.4kbps, allowed the voice calls in 1 country.
  • It used Analog Signal and AMPS was first launched in USA in 1G mobile systems

1g

Drawbacks:

  • Poor Voice Quality
  • Poor Battery Life
  • Large Phone Size
  • No Security
  • Limited Capacity
  • Poor Handoff Reliability

2G Technology:

  • 2G technology refers to the 2nd generation which is based on GSM.
  • It was launched in Finland in the year 1991 and used digital signals.
  • It’s data speed was upto 64kbps.

2G

Features include:

  • It enables services such as text messages, picture messages and MMS (multi media message).
  • It provides better quality and capacity.

Drawbacks:

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

2.5G Technology

2.5G is a technology between the second (2G) and third (3G) generation of mobile telephony.
It is sometimes described as 2G Cellular Technology combined with GPRS.

2.5G

Features Includes:

  • Phone Calls
  • Send/Receive E-mail Messages
  • Web Browsing
  • Speed : 64-144 kbps
  • Camera Phones

3G Technology:

  • 3G technology refer to third generation which was introduced in 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.

3G

Features Include:

  • Providing Faster Communication
  • Send/Receive Large Email Messages
  • High Speed Web / More Security
  • Video Conferencing / 3D Gaming
  • TV Streaming/ Mobile TV/ Phone Calls
  • Large Capacities and Broadband Capabilities
  • 11 sec – 1.5 min. time to download a 3 min Mp3 song.

Drawbacks:

  • Expensive fees for 3G Licenses Services
  • It was challenge to build the infrastructure for 3G
  • High Bandwidth Requirement
  • Expensive 3G Phones.
  • Large Cell Phones

4G Technology:

  • 4G technology refer to or short name of fourth Generation which was started from late 2000s.
  • Capable of providing 100Mbps – 1Gbps speed.
  • One of the basic term used to describe 4G is MAGIC.

4G
