WHAT IS 5G TECHNOLOGY?
5G
technology is a trending technology at present. What exactly 5G technology is? 5G
stands for the fifth generation of wireless mobile technology. The 5th
generation of cellular technology provides enhanced speeds, responsiveness,
more reliability, and coverage of
wireless networks. Experts say 5G is expected to
revolutionize the networks, workplace, and enhance consumer experiences. 5G wireless
technology is meant to provide us with high-speed internet. Because 5G will deliver
a higher multi-GBPS peak data speed. 5G technology will provide fast internet,
the Internet of Things (IoT), and low latency communication. The massive
machine-to-machine type of communication will enable the Internet of Things,
where millions of devices can be connected without human intervention. And
these devices use a wireless network to communicate with each other wirelessly.
How fast is 5G technology?
In
number, it is 10 gigabytes per second. But in reality, 5G is 20 times faster than
4G. The reason behind 5G having a higher speed than the other networks. This is due to the communication principle which says the shorter the frequency
larger the bandwidth. So 5G uses shorter frequencies. And that's the reason why 5G
can be faster. Because it will have a high band 5G spectrum which will provide
the expected boost in speed. And also other features like capacity low latency
and quality. But at present, the 5G download speed could differ widely by area.
Next
is the latency, the term latency is the delay between sending and receiving
information and 5G is having very low latency. What is 5G low latency? The
delay between sending and receiving information is very low at 5G compared to
the other networks. The latency of the 4G network is around 50 milliseconds (50ms)
while 5G network the average is 10 milliseconds (10ms) and the best case is
around one millisecond (1ms). So we can see how fast 5G is.
Uses of having low latency in 5G technology
The
following are a few examples of areas where low latency of 5G technology is used.
Autonomous Vehicles
Autonomous
vehicles are a good example where latency is of utmost importance. Because
autonomous vehicles are capable of sensing their environment and operate without any human involvement. So vehicles moving at high speeds need almost
real-time information from their surroundings and during the development of 5G,
even self-driving vehicles were kept in consideration.
A
few examples of autonomous vehicles are Autonomous electric cars, Self-driving
mini-trucks, Self-parking car systems, and Satellite-controlled vehicles. The smart
vehicle can respond to hundreds of arriving data and communicate its reaction
back to other vehicle and road signals within milliseconds. We can see the
future is going to be quite weird and interesting.
Smart Factories
Smart
manufacturing is a full computer integrated collaborative manufacturing system.
Internet of Things (IoT)
The
increase of speed in 5G allows the IoT devices to communicate and share data
faster.
Telemedicine
In the
telemedicine sector, one is the remote monitoring and surgery system. The other
one is latency and medical devices that need extreme precision. Because even
the slightest delay can be problematic in critical situations. So 5G will also
enable remote monitoring and surgery.
Online gaming
Gaming
is everything at present and games are all about the reaction time and a delay. This can
cause you to miss your show shot in a shooting game or handle a turn in a
racing game.
The
evolution from 4G to 5G is beyond data speed. For example, low latency gives
real-time connectivity for services using the cloud. This is the key to the success
of self-driving cars. And also the lower power consumption is what will allow connected
objects to operate for months or years without the need for human help. According
to the research done 5G must be able to support 1 million devices per square
kilometer.
Non-standalone and standalone 5G
There
are two 5G deployment options. That is non-standalone and standalone 5G. In
non-standalone 5G, the 5G radios will be used to provide fast data to the
end-user, and for the control and the signaling 4G architecture will be used. So,
currently, most of the 5G deployment which is going in the world is based on
this non-standalone 5G. The advantage of this non-standalone 5G is that the
existing 4G infrastructure can be used for the 5G deployment. But the true
potential of the 5G can be experienced only in the standalone 5G. Where the core
is based on the 5G architecture, and the new radios which are used in the 5G deployment
are based on the millimeter-wave frequencies. The mobile network operator will be
proceeding towards the standalone 5G. But it will take some time. So, even in
the counties, where this 5G deployment is going on, it will take some time, to
experience the true 5G features.
5G Vs 4G comparison
4G
refers to the fourth generation of mobile communication standards. And 5G refers
to the fifth generation of mobile communication standards.
Latency
of 4G varies from carrier to carrier. While 5G has extremely low latency
capabilities.
4G has a relatively low peak speed. While 5G is almost 20 times faster than 4G related to speed and the minimum peak download speed of 4G is around 1 gigabyte per second. While the minimum peak download speed of 5G is 20 gigabytes per second.
The pros and cons of 5G
Pros of 5G network include faster speed in the transmission, low latency, increased capacity, high-level bandwidth, and powering innovation. Because of this speed downloading, web browsing, or video streaming could be done without any interruption with 5G. And we will be able to use YouTube and any platform without any buffering or delay. The cons of the 5G network include limited global coverage, decreased bypass distance, upload speeds, devise batteries, and cyber security. The main problem about 5G at present is that the millimeter-wave signal in 5G can be blocked by objects like trees, walls, and buildings. But for this problem, there were different solutions which were presented about this like how to get around this issue. But the most accepted one involves using many nodes around each block of a populated area. So that 5G used device can use an air interface switching from node to node. So, we should have a lot of nodes when you are driving through the city you are automatically connected to the network. Most of these problems will be reduced with time as this technology is still in making.
