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 moreCan millimeter waves penetrate walls?
mmWave doesn’t penetrate walls Most building materials, such as cement and brick, attenuate and reflect very high-frequency signals with a big enough loss you’re unlikely to receive a very useful signal moving from inside to outside.
Read moreWhy do we use MM waves in communication?
In telecommunications, millimeter wave is used for a variety of services on mobile and wireless networks, as it enables higher data rates than at lower frequencies , such as those used for Wi-Fi and current cellular networks. Propagation restrictions dictate the use of small cell sizes for Wi-Fi and cellular networks.
