Technology
The new 5G technologies is to develop in the world
as the fastest and latest technology in the telecommunication world.
The 5G generation
technology for cellular systems will probably start to come to around in 2021.
First
generation
1. 1G:First technology
phones were analogue and were the first mobile
or cellular phones to be used. Although revolutionary in their time they
offered very low levels of spectrum efficiency and security.
Second generation
2. 2G: Second technology
This technologies were based around digital
technology and offered much better spectrum efficiency, security and new
features such as text messages and low data rate communications
Third generation
3. 3G: Third technology
This technology was to provide high speed
data. The original technology was enhanced to allow data up to 14 Mbps and
more.
Fourth generation
4. 4G: Fourth technology
This generation all-IP based technology
capable of providing data rates up to 1 Gbps.
Fifth generation
5. 5G: Fifth technology
One
of the big challenges facing 5G is standardization. There are already multiple
groups working to come up with standards around interoperability, backward
compatibility with older technologies (4G, 3G), and making sure the network
will be future-proof. While many companies agree that a global standard is
needed Building the infrastructure for 5G is also a huge task, with issues
around spectrum and installing new antennas. 5G is likely going to rely, at
least in part, on higher-frequency bands. There is more space in those airwaves
available, but at such high frequencies, signals can’t travel nearly as far as
they can over the frequencies used for 4G, resulting in a poor connection
One major
enabler for 5G will be the release of frequency spectrum and this needs to be
managed on a global scale to ensure commonality and also the reduction of
interference between services, especially those operating globally. This
process is managed under the auspices of the International Telecommunications
Union, ITU.
To manage the process of spectrum allocations, large
international meetings called the World Radio Conference, WRC are held every
four years. There is one in 2015, another in 2019, and this is followed four
years later by one in 2023..
5G Creating new communication
The future of mobile
communications is likely to be very different to that which we are used to
today. While demand for mobile broadband will continue to increase, largely
driven by ultra high definition video and better screens, we are already seeing
the growing impact of the human possibilities of technology as the things
around us become ever more connected.
