Millimeter Wave

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
  • 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 mmWaves don’t propagate and interfere with other neighboring cellular systems.

Significance of recent agreement

• It will also encourage small and medium scale industries to setup their manufacturing units in India which will create job opportunities to 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 generate Intellectual Property Rights (IPRs) and develop a skilled workforce to support the emerging millimetre wave/Sub-THz technology for 5G/6G.

Q1: What are Electromagnetic waves?

Electromagnetic waves such as light are generated by the vibration (energy transformation) of electrically charged particles. These waves are characterised by their oscillating electric and magnetic fields, which move perpendicular to each other and the direction of wave propagation.
