5G antennas are wireless nodes that can handle the increased data transmission rates and energy output of 5G signals. They differ from traditional 4G towers in that they are highly directional, meaning there must be a line of sight with a 5G antenna for connection to occur. 5G antennas are much smaller than typical wireless antennas, and are designed to fit onto telephone poles, buildings, inside rooms, and even under desks. 5G antennas are less power-hungry than 4G antennas, as they can turn off antennas in low traffic areas, whereas a 4G tower would have to radiate waves to that area regardless of traffic. 5G antennas can also support over 1000 more devices per meter than 4G counterparts, reducing latency and increasing precision.
5G antennas are not all built the same; due to the increased frequency range, 5G technology benefits from a so-called multi-layer spectrum. Depending upon the application, specialized antennas are used to optimize that specific range of frequencies employed. For example, signals in the 6-10 GHz range can somewhat penetrate objects, making them more useful for environmental monitoring, transportation, and smart city applications. Waves beyond 24 GHz, while non-penetrating, are perfect for machine-to-machine (M2M) communication and direct connections. Each of these ranges will require two different 5G antenna types, each with different form factors and power requirements.
Internal antennas for wireless devices must also be updated to receive the full benefits of 5G. These components are typically chipsets that transmit incoming and outgoing wireless signals, converting them into useful data for the device (this could be video information, text, etc.). These components, while smaller than networking antennas, are needed to ensure that devices can handle the increased bandwidth of information from 5G service providers.
