Exploiting the millimeter wave (mmWave) band is an attractive solution to accommodate the bandwidth-intensive applications in device-to-device (D2D) communications. The directional nature of communications at mmWave frequencies and mobility of devices require beam alignment at both transmitter and receiver ends. The beam alignment signaling overhead leads to a loss in the network&#x20... https://www.shoppurpledoorboutiquers.shop/product-category/hair-clip/
