Step-by-step and well-researched improvements made upon the first generation networks have resulted in the gradual up-gradation to the current fifth generation. To know the benefits of 5G, it is essential to briefly know about the innovations each generation brought in. Read on.
The earliest cellular phones belong to the 1G family. 1G is what made human-to-human communication over networks possible. It was launched in the 1980s and utilized analog radio signals. That is, it supported only voice calls.
The shift from analog voice to digital voice happened with the development of the 2G network. It was launched in the 1990s and made use of digital radio signals. That is, it supported both voice and data transmissions within a bandwidth of 64 kbps.
The era of mobile broadband and mobile internet access began with 3G technology. Launched in the 2000s as telephone signals transmitted at a speed of 1 to 2 Mbps meant that the technology allowed voice calls, digitized voice, and conferencing.
With 4G the speed of the internet drastically grew. Launched in the 2010s, 4G ran at a maximum speed of 100 Mbps-1 Gbps. As a faster and better version of 3G, 4G enabled high internet speeds, streaming, apps, and virtual reality.
5G is a leap. It has a more standard air interface that is capable of connecting the entire world. It was launched in the 2020s and has a speed of more than 1Gbps. It will undoubtedly make connection, connectivity, and control easier for consumers, the government, and the business sector.
Difference Between 5G And 4G
Although 4G networks are widespread today, they are not yet up to the task of supporting the burgeoning demand for data from expanding mobile devices. 5G networks are designed to provide the data capacity that will help handle the increasing number of connected devices that are already on the market while opening up the airwaves to innovative use cases such as driverless cars. In addition, 5G networks will allow for the faster transfer of real-time data to and from the internet.
Both 4G and 5G utilize millimeter-wave radio waves to achieve low-latency connections that are capable of covering large areas. Nevertheless, both 4G and 5G are based on different spectrum bands. This means that they do have a few key differences. Let us look at the table below to easily understand and remember these technology versions:
|5G makes use of higher radio frequencies of 28 GHz. High-frequency connectivity results in it being energy-efficient, precisely 90 percent more energy efficient than 4G.||4G makes use of lower radio frequencies of 700 MHz to 2500 MHz which are not energy efficient.|
|5G has the capability to transfer more data at a faster speed.||In comparison, 4G transfers lesser data at a lesser speed.|
|5G guarantees lower latency. The maximum possible latency is 1 millisecond, and the expected latency is 10 milliseconds.||The 4G network operates with a greater latency. For 4G, the latency is roughly 20 to 30 milliseconds..|
|This technology uses a millimeter-wave spectrum which means that there is an increase in connected devices in terms of coverage area. In geographic terms, 5G can connect one million per square kilometer.||4G does not support maximum internet coverage per geographical area. It provides about 4,000 devices per square kilometer.|
|By using new digital technology 5G improves speed, capacity and coverage.||4G has caused congestion and lesser coverage. It is less efficient when compared to 5G.|
What Are The Features Of 5G Technology?
What are the features of this high-speed 5G technology? 5G has the potential to revolutionize countless industries, economies, and even daily life with its advanced capabilities. Here are a few pointers dictating the features of 5G technology
- Increased bandwidth and speed
- Low latency
- Greater density
- Power efficient
5G technology uses higher radio frequencies and less cluttered airwaves to increase signal coverage. These higher bands, called millimeter waves, can carry more data faster. 5G operates in the millimeter-wave spectrum (30-300 GHz). Previously, these bands were unused, expensive, and unavailable to most people. Additionally, they are susceptible to blocking by physical objects. To overcome this, 5G will use multiple antennae. If the technology proves to be a success, we will soon see it on our phones.
In a nutshell, 5G has a much higher data capacity and speed internet than 4G LTE networks. You can expect your 5G home broadband to download movies in just seconds, stream 4K movies without buffering, and experience seamless virtual reality or augmented reality. The new technology will also enable higher capacity, and low latency, and allow remote processing to be done in real-time. Hence, it will be a huge benefit to businesses and consumers.
What Are The Different Band Of 5G?
There are three types of 5G spectrum: low, mid, and high-frequency spectrum bands. Each frequency band has a different speed and range and is used for different purposes. Let’s take a look at each one separately:
Low-band 5G transmits at 600 to 700 MHz and offers blanket coverage of large areas. It does have good coverage and internet speed for data exchanged but the maximum speed is capped at 100 Mbps. So, it can serve specific industry demands of coverage, especially in telecommunication where there is no strict demand for high speed.
Mid-band 5G provides higher peak speeds but has limitations in terms of penetration of signals and coverage. Mid-band 5G is expected to become the most common implementation of 5G networks in the coming years. This is because the mid-band 5G spectrum is a logical compromise between network speed, network efficiency, and coverage, and it is suited for medium-density urban areas and less-dense rural areas.
High-band 5G spectrum provides the highest speed among the three bands. However, it has far more limited coverage and signals penetration strength.
The first 5G networks are being rolled out in the US and in Europe. While high-band 5G is already gaining ground in the UK and US, low-band 5G will follow in a few years.

Challenges For 5G Rollout In India
Recently the Ministry of Communication has confirmed that mid and high-band 5G spectrum is expected to be made use of by Telecom Service Providers to roll out 5G technology-based services.
While the country has made progress in increasing fiber connectivity, challenges still lie ahead. Currently, only 34% of mobile towers in the country are fiber-optic, a key prerequisite for 5G rollout. Fiberization is also required to avoid spectrum wastage. As spectrum is highly expensive, telecom operators are eager to invest in fiber but are faced with challenges, such as right-of-way. Industry estimates suggest that India will need to invest approximately Rs 45,000 crores in fiber infrastructure by 2024.
One of the biggest challenges to the Indian 5G rollout involves cost. The technology is still in its early stages of development. The Indian market is much smaller than that of the US, but the 5G potential is considerable. It will create more jobs and contribute to inclusive growth. But it will need a complete revamp of the existing communication systems. To be effective, 5G will need to change the fundamental architecture of the existing communication systems. Unlike the existing 4G and 3G networks, 5G cannot carry large amounts of data over long distances. There are many other challenges, but fiber connectivity infrastructure and cost remain at the top of these.
Today, major telecom carriers are rolling out 5G networks in populated areas. In the U.S., T-Mobile has started rolling out its 5G network using Sub-6 technology. All major U.S. carriers are working to build nationwide captive networks using 5G. However, it will likely take a few years before 5G is available everywhere.
The Indian government has been moving steadily toward 5G technology but is lagging behind on implementation. It may be too late to catch up with the international competition. By the time India rolls out 5G services, the world may have already moved on to 6G networks. And if the country waits, it will be too late to catch up. And by then, 5G technology might be too late to catch up as 6G might be on the way!
