Description: The 3.5 GHz band is a frequency commonly used for 5G services, situated in the microwave range of the electromagnetic spectrum. This band is particularly relevant for the implementation of fifth-generation mobile networks, as it offers a balance between coverage and capacity. Frequencies in this band allow for faster and more efficient data transmission, which is crucial for supporting applications that require high speed and low latency, such as augmented reality, the Internet of Things (IoT), and high-definition video streaming. Additionally, the 3.5 GHz band has the advantage of being less susceptible to interference from physical obstacles, improving signal quality in dense urban environments. In terms of spectrum allocation, many countries have begun to release this band for commercial use, facilitating the expansion of 5G networks. In summary, the 3.5 GHz band is an essential component in the evolution of telecommunications, enabling operators to offer more advanced and efficient services to their users.
History: The 3.5 GHz band has historically been used for telecommunications services, including WiMAX and some satellite applications. With the advent of 5G networks, many countries began to reconfigure the use of this band to maximize its potential for mobile data transmission. In 2019, the Federal Communications Commission (FCC) in the United States held an auction to free up spectrum in this band, marking a milestone in the adoption of 5G in the country.
Uses: The 3.5 GHz band is primarily used for the implementation of 5G networks, enabling high-speed and low-latency data transmission. It is also employed in Internet of Things (IoT) applications, where a constant and reliable connection is required. Additionally, this band is used in some satellite communication systems and in wireless access technologies like WiMAX.
Examples: An example of the use of the 3.5 GHz band is the 5G network implemented by operators like Verizon and AT&T in the United States, which use this frequency to provide high-speed services in urban areas. Another case is the use of this band in IoT communication systems, where devices like sensors and security cameras connect via 5G networks to transmit data in real-time.
