In this article we will learn about how mobile and internet generations are being overlapped by another generation Mobile generations are launched by (International Telecom Union). Head Quarter:- Geneva, Switzerland. But the protocol is launched by ISO(International organization of standard)
0G(ZERO GENERATION):
It was based in half Duplex Used analog communication system
SMS not possible
Call waiting not possible
Call forwarding not possible
Digital games not possible
1G (First Generation)
It was based on a full-duplex Used Analog communication system
SMS not possible
Call waiting not possible
Call forwarding not possible D
Games not possible
2G(Second Generation)
It was based on a full-duplex Used digital communication system
SMS possible
Call waiting possible
Call forwarding possible
Digital games possible
The first time SIM Card was introduced TECHNOLOGY-Circuit switch Network technology was used in 2G SO 2G did not support internet
2.5G (2.5 GENERATION)
It was based on full-duplex Used GPRS TECHNOLOGY(General Packet Radio Service Technology) GPRS uses packet switching So 2.5G support internet
2.75G (2.75 GENERATION)
EDGE Technology was introduced EDGE-Enhanced Data for GSM EDUCATION EDGE technology introduced idle time concept in which data migrate to some other user when it is not being used
3G (Third Generation)
3G was launched on the basis of broadband technology As it promotes e-Governance In 3G, broadband technology W-CDMA W-CDMA (Wideband code division multiple access) W-CDMA used the protocols of CDMA and GSM both
3.5G (3.5 Generation)
HSDPA(High-speed downlink packet access technology) Was introduced. It provides higher speed in data receiving
3.5G+/H+/3.75G(3.75 GENERATION)
HSPA(High-speed packet access technology) HSPA= HSDPA(high-speed downlink packet access) +HSUPA(high-speed uplink packet access ) It provides higher speed in uplink and downlink both Therefore it becomes popular.
4G (Fourth Generation)
Speed is 100Mbps(megabit per second) to 1Gbps(Gigabit per second)
It is based on two technology WiMAX (worldwide interoperability of microwave access)
Launched by “sprint technology”
WiMAX uses a single ground-based static Antena that Provides a speed up to 50Mbps at a frequency of 5 to7.5GHz.
At this speed, it could not provide 4G protocol because of its low-speed LTE( Long Term Evaluation)
Launched by 3GPP(3RD generation partnership project)
LTE was launched two years later than WIMAX but it could reach Speed up to 100Mbps therefore it was considered as a 4G protocol
LTE works by paired Network therefore
it can provide higher speed
LTE can be attached with 3G,3.5G, etc but WIMAX does not have this facility. Another feature of LTE is VOLTE(Voice over long term evaluation)
In VOLTE voice calls also takes place in the form of data packets Therefore there are no charges for voice calls
5G(Fifth Generation)
speed 1Gbps to 10Gbps it was based on the internet of things(IoT) therefore it should have the least power consumption
5G has a maximum number of the antenna because it works MIMO MIMO(Multiple inputs multiple outputs) It means multiple input receiver antenna and multiple-output transmission antenna.
Higher is the MIMO more is the voice clarity and internet speed. I
subsequent generation MIMO increases therefore 5G has the highest MIMO.
5G has the lowest latency Latency is the time gap between the actual transfer of data and the command For the data transfer.
In subsequent generation, latency decreases, therefore, 5G has the lowest latency.
5G has the highest voice clarity, data transfer speed with the least time of connection But at the cost of more antennas.
