Millimeter wave (MM wave), also known as millimeter band, is the band of spectrum with wavelengths between 10 millimeters (30 GHz) and 1 millimeter (300 GHz) . It is also known as the extremely high frequency (EHF) band by the International Telecommunication Union (ITU).
Read moreWhat uses mmWave?
Millimeter-wave (mmW) frequencies (30–300 GHz) are being used for many applications in the modern world. These applications include,but not are limited to, radio astronomy, remote sensing, automotive radars, military applications, imaging, security screening, and telecommunications .
Read moreWhat is the range of millimeter waves?
Millimeter waves are electromagnetic (radio) waves typically defined to lie within the frequency range of 30–300 GHz .
Read moreWhat is millimeter-wave network?
Millimeter wave is a band of electromagnetic spectrum that can be used in a broad range of products and services, such as high-speed, point-to-point wireless local area networks (WLANs) and broadband access.
Read moreWhat is the need of millimeter-wave antenna?
Due to small wavelength, mmWave devices facilitate large antenna arrays to be packed in miniature physical dimension . Without varying antenna size, it is possible to pack more antenna elements at mmWave frequencies than at microwave frequencies resulting in narrower beam [1].
Read moreWhich problems we face at Millimetre wave frequency while designing antennas or any components?
Some of the common challenges are lack of infrastructure, research methodology, and cost . A few other are: Inter-cell interference; Efficient Medium Access Control; Traffic Management; Multiple Services; and, Communication, Navigation, & Sensing.
Read moreWhy does 5G use millimeter wave What are the shortcomings?
Following are the disadvantages/demerits of the 5G millimeter wave. Millimeter wave goes through different losses such as penetration, rain attenuation etc. This limits distance coverage requirement of mm wave in 5G based cellular mobile deployment. Moreover path loss at mm is proportional to square of the frequency.
