What is Smart Antennas in LTE

What is smart antenna? Smart antennas are antenna arrays with intelligent signal processing algorithms that identify spatial signal signatures, such as the direction of arrival of the signal, and calculate the following beamforming vectors and locate the beam antenna on the mobile / target. Why Need of Invent Smart antenna? At the beginning of wireless networks … Read more
