The global wireless standard has been advancing from one generation to the next with added benefits and features making life easy for one and all. When the 4G was rolled out, it was considered the latest version covering all aspects but this 5G mobile network rollout is said to have surpassed all the previous mobile network generations seen so far.
The latest is known as 5G, which is the 5th generation mobile network. It is a new global wireless standard after 1G, 2G, 3G, and 4G networks.
5G is innovative and much advanced compared to other mobile networks as it is designed to connect virtually everyone and everything together at one go including machines, objects, and devices
Before the onset of mobile, less had we known, we could communicate from anywhere with a device in our hands not only over voice but also by text. This was a new thing back in the 2G era and fascinating technology magic. The SMS services started from the 2G era, and with more advances in the mobile networks, and necessity came in the 3G network that brought Internet Browsing from the desktop/laptop to mobile devices. The need for browsing from a fixed stationed workstation seemed like a bygone era. The onset of the 4G network revolutionized the use of calls, SMS, internet usage, various applications, gaming, and much more.
Now the world is talking about the era of 5G which is the most compatible, robust, and has a wide range of usage for the digital age. It is more prevalent in a situation where the world is moving towards digitalization than ever before. With this 5G coming into action, the dream of the Internet of things will soon be a reality and come true.
Let’s understand what is 5G and how it will affect us:
5G is the next generation of cellular technology.
Wireless chipmaker Qualcomm (in 5G testing) successfully achieved a download speed of 7.5 GB per second. However, the average speed is considered to be 1.5 to 2GB per second. This means that it will be up to 20 times faster than existing 4G. An entire movie will take only 17 seconds to get downloaded, while 4G takes about 6 minutes.
What is the situation in India?
5G has been deployed in 35+ countries globally and counting. We are seeing much faster rollout and adoption compared with 4G. Consumers are very excited about the high speeds and low latencies.
The Indian government is already working on testing and spectrum. The trial can be beginning in September. Chinese companies like Huawei are out. It may possibly have a commercial launch in 2021-22.
How does 5G get such speed?
5G uses another technique for speed. It does not have many switching centers. For example, we would like to search the web on a smartphone, it is common to expect a response of a 50 to several hundred-millisecond difference. The reason being, the signals have to pass through several switching centers. In 5G this delay is seen to be much lesser.
What technology is being used in it?
5G is more than just its speed. In addition to higher peak data rates, 5G is designed to provide much more network capacity by expanding into a new spectrum, such as Millimeter.
Currently, our smartphones or TVs run at frequencies below 6 GHz. It is now time to use Millimeter waves. But Millimeter waves do not cross trees or buildings. Therefore small cell technology is being combined with it. Massive MIMO is also being used.
Why is 5G taking too long?
The serving range in 2G was 5 km. That is, a tower could cover such a large area. In 3G and 4G, this range continued to decrease, meaning the need for towers increased. The range in 5G will be hardly 50 to 100 meters, that is, there will be too many towers required for a seamless 5G Network. It takes time.
Apart from this, it will be used in real-time. For example, if a driverless vehicle is running and a sudden signal goes, then an accident will occur. This is the reason why much care is to be taken in this.
Uses of 5G?
5G is a unified, more capable air interface. It has been designed with an extended capacity to enable next-generation user experiences, empower new deployment models, and deliver new services.
With high speeds, superior reliability, and negligible latency, 5G will expand the mobile ecosystem. 5G will impact every industry, making safer transportation, remote healthcare, and precision agriculture.
5G will provide high-speed mobile data, Internet of Things, Driverless Transport, Smart cities, Remote Education, Remote Surgery, Virtual reality, and very fast real-time updates.
America, South Korea, China are leading in 5G service.
5G is said to revolutionize the mobile network space witnessed so far. The world moving into digitalization, and the demand for a fast, efficient, and robust network with the least lead and lag time, 5G looks not only promising but meets the needs of the new digital world.
