5th Generation mobile networks are generally referred to as 5G. Instead of providing peak internet speed it aims at higher capacity than 4G hence allowing large number of mobile users per unit area and allows consumption of higher or unlimited data quantities. This would help a large population to stream High Definition (HD) contents without buffering.
The new technology has been recently discovered by scientists to provide the data 10 times faster than 5G and it is expected to arrive in the market by 2020. Researchers from Hiroshima University as well as National Institute of Information and Communications Technology in Japan have announced the development of a terahertz (THz) transmitter that is capable of transmitting digital data at the rate exceeding 100 gigabits per second over a single channel with the help of 300-gigahertz band. To improve the rates of data transfer within limited bandwidth it is necessary to apply digital modulation technique such as QAM (Quadrature Amplitude Modulation). QAM is basically a method of combining two amplitude-modulated (AM) signals into a single channel, hence helps in doubling the effective bandwidth.
The terahertz (Thz) transmitter could make it possible for the whole content on a DVD (digital versatile disk) to be transferred in a fraction of a second. Terahertz offers high speed links to satellite as well as to the wireless that helps in boosting the speed of internet. This also includes downloading the contents from the server to the mobile devices faster than expected and ultrafast wireless links between base stations. The THz band is a new frequency resource expected to be used for future ultrahigh-speed wireless communications. The THz band is a frequency band that currently is not commonly used for wireless communications. It is generally popular because of employing frequencies even higher than those used by millimeter wave networks having the range of 57 to 66 GHz as well as having a much wider bandwidth.
Really! This quality of THz band is perfect for high-speed communication and the group of scientists is moving forward to implement it. They have confirmed that the speed of this transmitter would be 105 giga bits per second (gbps) and the frequency range should be in between 290 GHz to 315 GHz. This range of frequencies are currently unallocated but fall within the frequency range from 275 GHz to 450 GHz, whose usage is to be discussed at the World Radio communication Conference (WRC) that is going to be held in 2019 under the International Telecommunication Union Radio communication Section (ITU-R).
Terahertz wireless is high data rate and minimum latency rate communication transmitter. The scientists are continuously focusing it as the needs of the human beings are increasing to get high speed data at workplace, home and during travel. Nowadays, the whole life is getting dependent on smart phones and high speed data as in this corporate world nobody has enough time to interact with others because the life is getting busier and in such a scenario the use of electronic gadgets such as laptops, mini and tabs more attracting the people. For getting things done online without waiting for fraction of seconds they need the high speed and it can be provided with the help of this new emerging technology.
As in 2016, we had seen that scientists and research scholars said that the speed of a wireless link in the 300 GHz band can be increased with the help of Quadrature Amplitude Modulation (QAM) but in 2017 they are coming up with a new idea. As per their research it has been clearly shown that the data rate must be six times higher and the speed would get increased upto 100 gbps due to this integrated circuit based technology. The scientists further put their words by saying, we talk data rate in mega bits per second (mbps) or giga bits per second (gbps). But now we are approaching towards tera bits per second (tbps) using a plain simple single communication channel. The target to reach this speed is by 2020 which is three years away and still we have to see any advancement in this technology during the upcoming years.
