Description: The 2100 MHz band is a frequency primarily used in mobile telecommunications, especially in third-generation (3G) services and some fourth-generation (4G LTE) services. This band is situated in the microwave frequency range, allowing for high-speed data transmission with good penetration capability in urban environments. The use of this band is crucial for the expansion of mobile networks, as it offers a balance between coverage and capacity. In the context of 5G networks, the 2100 MHz band can be used to complement higher frequencies, providing greater coverage in areas where higher frequencies may not be as effective. Additionally, its use in 3G and 4G has allowed telecommunications operators to optimize their networks, offering voice and data services more efficiently. The 2100 MHz band is, therefore, an essential component in the evolution of mobile networks, facilitating the transition to more advanced technologies like 5G.
History: The 2100 MHz band began to be used in the 2000s with the implementation of 3G networks, allowing mobile data transmission at significantly higher speeds than those offered by previous technologies. As the demand for mobile services grew, this band became one of the key frequencies for telecommunications operators worldwide. With the arrival of 4G LTE, some operators began to use this band to enhance their network capacity, although its use has been complemented by higher frequency bands in the context of 5G.
Uses: The 2100 MHz band is primarily used for voice and data services in 3G and 4G LTE mobile networks. It enables high-speed data transmission, which is essential for applications such as internet browsing, video streaming, and real-time communication. Additionally, in the context of 5G, it can be used to enhance coverage in areas where higher frequencies are not effective, thus facilitating a smoother user experience.
Examples: An example of the use of the 2100 MHz band is its implementation by operators such as Vodafone and Orange in Europe, where it is used to provide 3G and 4G services to their customers. In some countries, this band has been reconfigured to support 5G services, allowing users to enjoy faster connection speeds and better coverage in dense urban areas.
