larger number of devices, with a more consistent connection, and to support new
technologies such as self-driving cars and augmented reality. It is expected to
enable faster download and upload speeds, lower latency, and improved reliability
compared to 4G networks.
5G networks use a higher
frequency range than previous generations of cellular technology, which allows
for much faster data transfer rates. This means that 5G networks will be able
to handle more data traffic, and will be able to support more devices at the
same time. Additionally, 5G networks will have lower latency, which means that
the time it takes for data to be sent and received will be shorter. This will
be especially important for applications like self-driving cars and virtual
reality, where real-time communication is critical.
5G networks will also be more
flexible and efficient than previous generations. They will be able to
dynamically allocate resources to different devices and services as needed,
which will help to ensure that everyone has a consistent and reliable
connection. Additionally, 5G networks will be able to support a much wider
range of devices and services, including things like smart cities, the internet
of things, and industrial automation.
5G networks will also be more
secure than previous generations. They will be built on a more robust and
flexible architecture, which will make it harder for hackers to penetrate the
network. Additionally, 5G networks will include built-in security features such
as encryption and authentication, which will help to protect data and devices
from unauthorized access.

Road to 5G…
1G/1st generation - 1G, or first generation, refers to the first generation
of cellular network technology. It was developed in the 1970s and 1980s and was
the first generation of analog cellular networks. 1G systems were based on
analog radio technology and used circuit-switched voice communication.
The first commercial 1G
network, the Motorola DynaTAC 8000X, was launched in 1983 by the American
carrier AT&T. It had very limited capabilities, only allowing for 30
minutes of talk time and 8 hours of standby time. It was also quite bulky,
weighing in at 2.5 pounds (1.1 kg) and measuring 13 inches (33 cm) tall.
1G technology had a number of limitations, including poor call quality, low capacity, and limited coverage area. It was also relatively expensive, and the phones were large and heavy. Despite these limitations, 1G networks were an important step forward in the development of mobile communication technology, as they enabled people to make phone calls from anywhere.
2G/2nd generation - 2G, or second generation, refers to the second
generation of cellular network technology. It was developed in the 1980s and
1990s and was an improvement over the first generation (1G) of cellular
networks. 2G networks were based on digital radio technology and used packet-switched
data communication.
The first 2G network, GSM
(Global System for Mobile Communications) was launched in Europe in 1991 by the
carrier, Radiolinja (now part of Elisa Oyj) in Finland. 2G networks provided
several improvements over 1G networks, including improved call quality,
increased capacity, and wider coverage area. 2G also introduced the concept of
text messaging (SMS) which was not possible on 1G.

What is edge computing?
Edge computing refers to a
distributed computing paradigm in which data, compute, storage and applications
are brought closer to the sources of data, such as devices, sensors, and
gateways. This allows for processing of data to be done closer to where it is
generated, rather than in a central location such as a data center or cloud.
In edge computing, data is
processed and analyzed at the edge of the network, near the source of the data,
rather than being sent to a centralized location for processing. This reduces
the amount of data that needs to be sent over the network, which can help to
reduce latency, increase security, and reduce costs.
Edge computing is often used
in combination with cloud computing, where data is first processed at the edge,
and then sent to the cloud for further analysis, archiving or backup.
Edge computing is particularly
useful in cases where low latency, high bandwidth, or high availability is
important. It can be used in a wide range of applications such as IoT,
autonomous vehicles, augmented and virtual reality, and industrial automation.
One of the main advantages of
edge computing is that it allows for real-time data processing and
decision-making, which is critical for many applications such as autonomous
vehicles, industrial automation, and IoT. Additionally, edge computing enables
the development of new use cases which were not possible with a centralized
architecture, such as low-latency video processing, or video analytics in a
remote location.
In summary, Edge computing is
a distributed computing paradigm where data, compute, storage and applications
are brought closer to the sources of data such as devices, sensors and
gateways, this allows for processing of data to be done closer to where it is
generated, rather than in a central location such as a data center or cloud. It
