5g specifications wireless technology
5g specifications wireless technology :- By each passing day, the world of technology takes a giant leap forward. And when it comes to the matter of wireless technology, it has been progressing by leaps and bounds.
In the year of 1982, Nordic Mobile Telephone introduced the first 1G system. Since then 2G came in 1992 followed by 3G in 2001 and 4G in 2012.
Since the successful implementation of 4G technology and the initial release of LTE in Scandinavia in 2009, NASA has partnered with Machine-to-Machine Intelligence (M2Mi) Corporation for the development of 5G technology.
Recently the official name and logo has been announced by the 3GPP cellular standards group and it has been confirmed that 5G will be the official successor of 4G.
The 5G technology will be IoT-focussed (Internet of Things) and the International Telecommunication Union (ITU) has released some specifications regarding the 5G wireless technology.
High data rate
It has been said that for every mobile base station, there will be at least 20Gbps downlink and 10Gbps uplink available. It is the total capacity that can be handled by a single cell.
This is to say that in a fixed wireless broadband connection, users will be getting this amount of speed in a point-to-point connection.
This further indicates that these 20 gigabits of data will be split between all the users connected to a specific cell.
Another great specification of 5G wireless technology is that it has a dense connectivity. The 5G connection can provide service to at least 1 million connected devices in a square kilometre.
This means that it will be super efficient and will provide a better performing network at a lower investment cost.
Mobility of 5G
The connectivity of wireless devices gets disruptive whenever a user travels at a very fast pace, especially in trains.
From time to time companies have been trying to solve this problem and the recent breakthrough was achieved with the 4G technology service.
The 4G technology can support everything even at a speed of 200 km/hr. Similarly to the LTE and LTE-Advanced, the 5G technology will support anything from 0 km/hr to almost 500 km/hr.
Apart from this, the specification of 5g specifications wireless technology will reach into the deep urban and rural areas also. This will help the remote people to get access to hassle-free network.
Another great specification of the 5g specifications wireless technology is that it is highly energy efficient. From a state of high load it can drop into a low energy mode within moments.
For this to happen the control plane latency should be as low as 10ms, which means that a 5G enabled device would switch from high load stage to battery efficient stage within 10ms.
Latency is the time between a stimulated cause and the response it provides. LTE cells boasted of a latency of 20ms.
In case of 5g specifications wireless technology, the maximum latency would be just 4ms. Apart from that, the 5G connection will have a latency of just 1ms for ultra reliable low latency communications (URLLC).
Spectral efficiency means how many bits the technology can carry through the air per hertz of spectrum.
5G’s peak spectral efficiency is very close to the LTE-Advanced. It has a downlink of nearly 30 bits/Hz and for uplink, it is almost 15 bits/Hz.
These figures can be assumed as 8×4 MIMO (Multiple-input and Multiple-output), which is 8 spatial layers down and 4 spatial layers up.
Super fast mobile network
Thanks to densely clustered small cells in 5G connection, that will ensure a super high-speed connection. This will lead to a continuous coverage the urban and rural areas.
This could be possible due to the access to a spectrum under 4 GHz, perhaps via the world’s first global implementation of Dynamic Spectrum Access.
Another specification of 5G technology is its converged fibre-wireless network which is a first time for wireless internet access.
The millimetre wave bands (20 − 60 GHz) would allow the very wide bandwidth radio channels to support access speeds of up to 10 GB/s.
The real-world data rate
In the real world, the speed of the wireless connectivity will increase dramatically due to the new specifications of 5G technology.
The user can have a download speed of almost 100 Mbps and an upload speed of 50Mbps. With this speed there will be an increase in reliability and a decrease in drop-outs.
