Description: The 4 GHz band is a frequency used in wireless communications, particularly relevant in the context of 5G networks. This band falls within the microwave frequency range, which typically spans from 1 GHz to 300 GHz, and is known for its ability to offer high data transmission speeds and low latency. The characteristics of the 4 GHz band allow for better signal penetration in dense urban environments and a greater capacity to handle multiple simultaneous connections. This makes it an attractive option for applications requiring robust performance, such as high-definition video streaming, augmented reality, and the Internet of Things (IoT). In the context of 5G networks, the 4 GHz band is used to complement other frequency bands, providing a balance between coverage and capacity. Its use in telecommunications infrastructure is essential to meet the growing demand for connectivity and speed in the digital age, where mobility and constant connectivity are crucial for users and businesses.
