The world’s first cell phone call was made on April 3, 1973, when Martin Cooper, a senior architect at Motorola, called an adversary media communications organization and educated them he was talking by means of a cell phone. The telephone Cooper utilized, on the off chance that you could consider it that, gauged a stunning 1.1kg and estimated in at 228.6x127x44.4mm. With this model gadget, you got 30 minutes of talk-time and it took around 10 hours to charge.

Mobile Generation

Basically, the “G” means “GENERATION”. While you associated with web, the speed of your web is relying on the sign quality that has been appeared in letters in order like 2G, 3G, 4G and so on. The speed increments and the innovation used to accomplish that speed likewise changes. For eg, 1G offers 2.4 kbps, 2G offers 64 Kbps and depends on GSM, 3G offers 144 kbps-2 mbps though 4G offers 100 Mbps – 1 Gbps and depends on LTE innovation.

1^st Generation

This was the original of mobile phone innovation. The absolute original of business cell system was presented in the late 70’s with completely actualized guidelines being set up all through the 80’s

1G is a simple innovation and the telephones for the most part had poor battery life and voice quality was enormous absent much security, and would at times experience have dropped calls.

Key features (technology) of 1G system

Frequency 800 MHz and 900 MHz
Bandwidth: 10 MHz (666 duplex channels with bandwidth of 30 KHz)
Technology: Analogue switching
Modulation: Frequency Modulation (FM)
Mode of service: voice only
Access technique: Frequency Division Multiple Access (FDMA)

Disadvantages of 1G system

Poor voice quality due to interference
Poor battery life
Large sized mobile phones (not convenient to carry)
Less security (calls could be decoded using an FM demodulator)
Limited number of users and cell coverage
Roaming was not possible between similar systems

2^nd Generation

The fundamental distinction between the two cell phone frameworks (1G and 2G), is that the radio sign utilized by 1G system are simple, while 2G systems are computerized. It executed the idea of CDMA and GSM. During 2G Cellular telephones are utilized for information likewise alongside voice. 2G presented a considerable lot of the major administrations that despite everything we use today, for example, SMS, interior meandering. The maximum speed of 2G with General Packet Radio Service (GPRS ) is 50 Kbps or 1 Mbps with Enhanced Data Rates for GSM Evolution ( EDGE )

Key features of 2G system

Digital system (switching)
SMS services is possible
Roaming is possible
Enhanced security
Encrypted voice transmission
First internet at lower data rate
Disadvantages of 2G system
Low data rate

3^rd Generation

This generation set the norms for the greater part of the wireless technology, Web browsing, email, video downloading, picture sharing and other Smartphone technology were presented in the third era. Presented industrially in 2001 age portable correspondence were to encourage more noteworthy voice and information limit, bolster a more extensive scope of utilizations, and increment information transmission at a lower cost. The hypothetical max speed for HSPA+ is 21.6 Mbps. 3G developed into 3.5G and 3.75G as more highlights were presented

Key features of 3G system

Higher data rate
Video calling
Enhanced security, a greater number of users and coverage
Mobile app support
Multimedia message support
Location tracking and maps
Better web browsing
TV streaming
High quality 3D games

Disadvantages of 3G systems

Expensive spectrum licenses
Costly infrastructure, equipment’s and implementation
Higher bandwidth requirements to support higher data rate
Costly mobile devices
Compatibility with older generation 2G system and frequency bands

4^th Generation

4G is an altogether different innovation when contrasted with 3G and was made conceivable basically. Its motivation is to give rapid , high caliber and high ability to clients while improving security and turn down the volume and information administrations, sight and sound and web over IP. The maximum speed of a 4G arrange when the gadget is moving is 100 Mbps or 1 Gbps. 4G telephone can impart through a 3G or even 2G arrange. we have the partial parts: 4.5G and 4.9G denoting the progress of LTE

Key features of 4G system

Much higher data rate up to 1Gbps
Enhanced security and mobility
Reduced latency for mission critical applications
High definition video streaming and gaming
Voice over LTE network VoLTE (use IP packets for voice)

Disadvantages of 4G system

Expensive hardware and infrastructure
Costly spectrum (most countries, frequency bands are is too expensive)
High end mobile devices compatible with 4G technology required, which is costly
Wide deployment and upgrade is time consuming

5^th Generation

5G is an age as of now a work in progress , that is proposed to enhance 4G. 5G guarantees fundamentally quicker information rates, higher association thickness, much lower dormancy. The maximum speed of 5G is gone for being as quick as 35.46 Gbps , which is more than multiple times quicker than 4G. Cutting edge Mobile Networks Alliance feel that 5G ought to be taken off by 2020to satisfy business and buyer needs

Key features of 5G technology

Ultra fast mobile internet up to 10Gbps
Low latency in milliseconds (significant for mission critical applications)
Total cost deduction for data
Higher security and reliable network
Uses technologies like small cells, beam forming to improve efficiency
Forward compatibility network offers further enhancements in future
Cloud based infrastructure offers power efficiency, easy maintenance and upgrade of hardware
