Millimeter Wave

Why in the news?                        

Recently, the Centre for Development of Telematics (C-DOT) and the Indian Institute of Technology-Roorkee (IIT-Roorkee) have signed an agreement under the Telecom Technology Development Fund (TTDF) scheme of the DoT with the development of a “millimeter wave transceiver for 5G rural connectivity”.

About Millimeter Wave:

• It refers to electromagnetic waves with frequency between 30-300 GHz and wavelength between 10 mm and 1 mm.
• Its frequency spectrum is used for wireless high-speed communications. It is also known as the extremely high frequency, or EHF, band by the International Telecommunication Union.

Advantages of Millimeter Wave:

• It enables higher data rates compared with lower frequencies when used in telecommunications, such as those used for Wi-Fi and current cellular networks.
• The higher frequency range has a high tolerance for bandwidth.
• It offers less latency due to its higher speeds and bandwidth.
• There is less interference, as mm waves don't propagate and interfere with other neighboring cellular systems.

Significance of recent agreement

• It will also encourage small and medium-scale industries to set up their manufacturing units in India which will create job opportunities for our own engineering graduates, due to the use of polymer-based structure in conjunction with metals.
• This will also reduce our over-dependence on semiconductor fabrication industries. The proposed cost for the development of technology is extremely small as against the opportunities it would create.
• Additionally, the project also aims to contribute to generating Intellectual Property Rights (IPRs) and develop a skilled workforce to support the emerging millimeter wave/Sub-THz technology for 5G/6G.
