What are the differences between 1G, 2G, 3G, 4G and 5G networks
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).
—————- 1G Technology——————
Country = Japan.
Band = 800MHz.
Poor voice quality.
Voice only network .
Poor battery life .
Large phone size
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. .
2g = digital signal
Base = GSM/CDMA
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.
Base = GPRS/EDGE
Send/receive Email messages
HSCSD data rate 236.8kbps by
using enhaced data rate for GSM
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.
Found Broadband technology
Bandwidth = 5-20MHz
Speed = 144kbps – 2Mbps
Send/Recive large mails
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
High speed = 100Mbps
Ultra Broad band
Bandwidth = 100Mhz
Speed Of 4G?
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
Facilities such as ultra-broadband Internet access,
streamed multimedia may be provided to users.
Speed = 100Mbps – 1GB
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
OFDMA – Orthogonal Frequency Division Multiple Access
SC-FDMA – Single Career Frequency Division Multiple Access
HSPA – High Speed Packet Access
HSDPA – High Speed Downlink Packet Access
DC-HSDPA – Dual-carrier HSDPA
HSUPA – High Speed Uplink Packet Access (NOKIA)
DC-HSUPA – Dual-carrier HSUPA
MC-HSPAM – ulti-carrier HSPA MC-HSPA
LTE – Long Term Evolution
