Description: The 28 GHz band is one of the millimeter frequencies used in 5G networks, characterized by its ability to offer high data transmission speeds and low latency. This band is situated in the millimeter wave frequency range, which oscillates between 30 GHz and 300 GHz. The use of the 28 GHz band allows telecommunications operators to implement advanced technologies that can support a large number of connected devices simultaneously, which is essential in an increasingly interconnected world. Additionally, this band is particularly suitable for applications that require high bandwidth, such as high-definition video streaming, augmented reality, and virtual reality. However, its range is limited compared to lower frequencies, meaning that a higher density of base stations is required to provide adequate coverage. Despite these limitations, the 28 GHz band is crucial for the development of 5G networks, as it enables operators to offer innovative services and enhance user experience in densely populated urban environments.
History: The 28 GHz band has been part of the evolution of telecommunications since the 1990s, when millimeter frequencies began to be explored for communication applications. However, its adoption for 5G networks accelerated in the 2010s, when 5G standards were defined and tests were conducted in various cities around the world. In 2016, the Federal Communications Commission (FCC) in the U.S. opened the 28 GHz band for commercial use, marking an important milestone in the implementation of 5G technology.
Uses: The 28 GHz band is primarily used to provide high-speed services in 5G networks, enabling large-scale data transmission and the connection of multiple devices in urban environments. It is particularly useful for applications requiring high bandwidth, such as 4K and 8K video streaming, as well as for the development of emerging technologies like augmented reality and virtual reality. It is also employed in the implementation of private 5G networks for industries requiring fast and reliable connectivity.
Examples: An example of the use of the 28 GHz band can be seen in tests conducted by telecommunications operators in cities like New York and San Francisco, where base stations were implemented to offer 5G services to users. Additionally, companies like Verizon have utilized this band to launch their 5G services in metropolitan areas, enhancing connectivity and user experience in high-demand applications.
