**5. Overview of 5G technology**

5G technology is built to use a variety of frequencies, including low, middle, and high-band spectrum, to provide faster speeds and greater coverage. Low-band 5G is frequently used to improve existing 4G networks and provides greater coverage (see **Table 3** for a comparison of 4G and 5G's key features). Mid-band 5G, which strikes a balance between speed and coverage, is used to support most 5G services. Although its range is limited, high-band 5G, also known as millimeter-wave 5G, provides the fastest speeds. In addition to beamforming and massive MIMO (multiple-input multiple-output) technology, 5G technology combines multiple frequencies to improve signal quality and reduce interference. Beamforming utilizes canny receiving wires to think the remote transmission in a specific region, upgrading signal quality and bringing down obstruction. Numerous antennas are used in massive MIMO to increase data transport efficiency and increase network capacity.
