South Korea was first given the 5G standard on 1 December 2018, and since the first cell phone call was made in 1973, there is ample reason to conclude that the moving industry has made considerable progress and evolution of smartphones. Mobile devices have changed our world in ways we could never have foreseen. In several nations, 5G is scheduled for 2020 and this will further push the Internet of Things (IoT) and Big Data.

Although formal 5G specifications have yet to be developed, at least three times the existing 4G standards are required to be established.

It is useful to map out the unstoppered increase of wireless standards from the first generation (1G) to the cusp of a global 5G rolley, to better understand how we got here.


However, several disadvantages have plagued 1G technology. Decking was weak and the quality of sound was low. There was no roaming support among different operators and there was no compatibility between systems because different systems worked on different frequency ranges. Worse still, calls have not been secured, meaning that anyone may call with a radio scanner.

1G was from 1987 to 1991.

“It’s been PHENOMENAL but not sufficient.”

What Happened Here?

  • The first SMS was sent to Engineer Neil Pap worth by the Vodafone Director Richard Jarvis on the 3rd of December, 1992, at the time of “merry Christmas.”
  • Creation of the Advanced Mobile Phone System (AMPS) technology for voice transmission from previous IMPS.
  • Connectivity generated mobile connectivity that introduces mobile voice services.
  • 1G Analog voice introduced. 1G

What Was Wrong?

  • Low-quality voice
  • Lifetime with poor battery
  • Big size phone
  • No protection
  • Ability limited
  • Bad trust

The Effect On Income

Since the prices were too high & customers too poor, the Telecom Revolution was just the beginning, and service providers at present were centered on technical developments, such as success stories over revenue generation and the acquisition of subscribers.


The second mobile network generation or 2G was introduced in Finland in 1991 under the GSM standard. Call could for the first time be encrypted and digital calls with less static and sound crackling were substantially clearer.

As 2G is digital, the possibility of transmitting data (not voice) over the airwaves has inevitably emerged. In the 1990s, too, mobile data could mean mobile internet access and public access were the sudden success of the Internet in the decade. However, let me tell you it wasn’t mobile broadband. That was ten kilobits a second. This was in range. Yeah, you read it right, that’s kilobits.

What Was Wrong?

  • Strong digital signals are needed to assist cell phones. Digital signals were reduced if there was no network coverage.
  • Complex data such as video could not be managed by systems.
  • The consumer specifications were too complicated to reach 2G when the generation went to 3G.

The Effect On Revenues

Although the most important highlight of the period may have been the incorporation of data transfer capabilities on a mobile device, SMS services seem to have a maximum effect on sales. In this period, telecommunications providers worldwide saw their turnover rise multiple times, some operators recorded 5x growth.

3G: Revolution Of The ‘Packet Upgrade’

NTT DoCoMo introduced 3G in 2001 to standardize vendor network protocols. This meant that users could access network networking data from anywhere in the world as ‘Data Packets.’ This made it possible for the first time to provide international roaming services.

3G’s enhanced capabilities for data processing (four times quicker than 2G) have resulted in new services including video conferencing, video streaming, and IP vocalization (such as Skype). Blackberry was introduced in 2002, and 3G networking supported many of its powerful features.

What Was Wrong?

  • Messy Building
  • Compatible 3G devices demanded
  • 3G system update costs were too high
  • The utilization of power was high

The Effect On Income

Operators concentrated on rising their customer base in the mid-2000s towards the dawn of 4G. They saw a rise of ~4.1 billion between 2002 and 2009. However, given that data prevailed over calls, the revenue rise was not sufficient. The need for a 3G compliant system/hardware has become a requirement because it allowed the transition of phones to smartphones. This time was an immense increase in sales for device manufacturers.

4G: The Age Of Fluxing

4G is first introduced as the Long Term Evolution (LTE) 4G standard in Stockholm, Sweden, and Oslo, Norway, in 2009. It was then launched globally and converted into reality high-quality video streaming for millions of consumers. 4G provides fast mobile web access to gambling services, HD videos, and HQ video conferenced services, (up to 1 gigabit per second for stationary users).

Although 4G is the new standard worldwide, there are regions with low 4G LTE coverage and network patchiness. Our claims that, for example, a mobile data portal, UK citizens are only 53% able to reach 4G networks.

What Was Wrong?

  • Network 4G LTE requires complex hardware.
  • Multiple antennas & transmitters use 4G technology, leading to low battery life.
  • Consumers have decreased to 3G in areas without 4G coverage while paying the 4G premium.
  • Increased data use

The Effect On Revenues

For the first time in 2018, almost 300 million people were connected to the Mobile Internet, adding more than 3.5 billion people to the global connected population. For operators especially in the tier 2 & 3 segments, revenues did not significantly increase, as customers were demanding better connectivity, higher bandwidth, and lower latency.

5G Age 2019 And Later

“5G is a promise of marvel, more than a generation”

The 5G looks at us for a new experience, including increases in fast data speeds, higher link density, much lower latency.

The 5G is not a 4G update but is in its range as it helps us to connect thousands of devices simulation, offering a true “real-time” feel to users.

That means that storage and processing will migrate into the cloud to minimize IoT devices by optimizing the network for the telecom operator. This means that the cost of development and maintaining is reduced.

5G’s superior networking promised to transform everything from banking to healthcare. 5G introduces the possibility of life-saving technologies, such as remote operations, telemedicine, and even remote sign monitoring.


As we saw, 5G will be the mobile network of the future, helping to understand the IoT and evolution of smartphones. Without the continuous technological advancement of 1G to the present day, this would not have been possible. As it comes points, IoT does not only speak to a fridge; it helps to improve human productivity countless times and the evolution of phones.
