We are Going to Discuss difference between 1G 2G 3G 4G Networks

What is the 1St Generation?


1St Generation, found in 1980s (japan) It transfer only voice in analog wave, it also has limitation because there are no encryption,

This system is called frequency-division multiple access (FDMA).

What is the 1St Generation?

—————- 1G Technology——————

Country = Japan.
Band = 800MHz.
Poor voice quality.
Voice only network .
Poor battery life .
Large phone size
No security
Limited capacity
Poor hand-off reliability
Interference problems (background noise, electronic)


What is the 2nd Generation?


2nd Generations, improved by introducing the concept of Digital modulation launched 1990 in Finland, Its the technology stand for Global System for Mobile communication (GSM).GSM mainly used for phone communication.
GSM provide services like, text messages SMS, picture messages MMS. .

What is the 2nd Generation?

—————-2G Technology—————-

2g = digital signal
Data speed = 64kbps
These systems are unable to
handle complex data such as videos
less battery power


What is the 2.5 Generations ?


2.5 Generations (GPRS) is a middle of 2G and 3G. In 2.5G,
they introduced packet-switched data to GSM* which is called GPRS..
GPRS- General Packet Radio Service. In this we can get higher data speed over GSM.. Disadvantage of GPRS is can’t sent data while voice call
GPRS improved as EGPRS or EDGE.

What is the 2.5 Generations ?

—————-2.5G Technology—————–

 Base = GPRS/EDGE
 Speed 64-144kbps
 Can call
 Send/receive Email messages
 Web browsing
 Camara phones
 HSCSD data rate 236.8kbps by
using enhaced data rate for GSM
evolution (EDGE)


how much speed 3G gives?


3rd Generations, 3g is faster than that of 2.5g. It allows data services..
HSPA is a third generation (3G) evolution of WCDMA that combines two extensions to UMTS — HSDPA .HSUPA (High Speed Uplink Packet Access-Nokia).
This system called code-division multiple access (CDMA) and improved its Wideband CDMA (WCDMA), In Japan called for this technology “FOMA(freedom of mobile multimedia access.” China called TD-SCDMA (time division – synchronous code division multiple access.

how much speed 3G gives?

—————3G Technology—————-

 Found Broadband technology
 Bandwidth = 5-20MHz
 Speed = 144kbps – 2Mbps
 Location Services
 Send/Recive large mails
 Videos conference
 TV streaming
 3D gaming



how much speed 3.5G gives?


3.5 Generations .Generation of 3rd is faster than that of 3g. It based on HSDPA means now get more speed on downloading or opening of any url than that of 3g case. 3.5g gives a speed of 384 kbps while 3g gives 128 kbps (actual Speed)..

 HSDPA upgrades the uplink = 1.4,1.9,5,8,Mbps
 HSUPA name is given by Nokia,
 Speed = 14Mbps
 Speed = 5.75 (HSUPA)


How much speed on 3.75G?


3.75 Generations .HSPA+ is a combination of HSUPA and HSDPA that improves the performance of WCDMA andcan attain speed 21Mbps to 28Mbps. as defined by the 3rd Generation Partnership Project (3GPP) Release 7 UMTS Specification for Mobile Terminated Equipment

 Multimedia Broadcast multicast services (MBMS)
 Enables Multimedia broadcast services like mobile tv
 Speed = 28Mbps


How much speed 3.9G ?


3.9 Generations In telecommunications, DC-HSPA+ Dual-Carrier HSPA+ is an enhanced version of HSPA+, as defined by the 3GPP Release 8 UMTS Specification for Mobile Terminated Equipment. DC-HSPA+ have double the branwidth and Downlink data rates.


 Speed = 28 Mbit/s – 42 Mbit/s


Speed of PRE – 4G?


PRE-4G WiMAX and Long term evolution (LTE) have been on the market since 2006 and 2009, and are often branded as 4G. The current versions of these technologies did not fulfill the original ITU-R requirements of data rates approximately up to 1 Gbit/s for 4G systems. Marketing materials use 4G as a description for LTE and Mobile-WiMAX in their current forms


 More security
 High speed = 100Mbps
 High Capacity
 Ultra Broad band
 Bandwidth = 100Mhz


Speed Of 4G?


4 Generations
these days in telecommunications, 4G is the fourth generation of wireless Communication standards.. Long term evolution (LTE), In 2008, the ITU-R organization specified the IMT-Advanced (International Mobile Telecommunications Advanced) requirements for 4G standards, setting peak speed requirements for 4G service at 100-1024Mbit/s

Speed Of 4G?

—————4G Technology—————-

 Facilities such as ultra-broadband Internet access,
 More security
 IP telephony,
 gaming services,
 streamed multimedia may be provided to users.
 Speed = 100Mbps – 1GB


What is the 5G technology 


What is the 5G technology


GSM – Global System for Mobile telecommunications
GPRS – General Packet Radio Service
EDGE – Enhanced Data rates for GSM Evolution
FDMA – Frequency Division Multiple Access
TDMA – Time Division Multiple Access
CDMA – Code Division Multiple Access
WCDMA – Wideband CDMA
