Description: The Sub-6 GHz band refers to radio frequencies that are below 6 GHz and are used in mobile telecommunications, including 5G networks. This band is crucial for providing wider coverage and better signal penetration in both urban and rural environments. Unlike higher frequencies, which offer faster data speeds but have limited range, Sub-6 GHz bands allow signals to travel further and penetrate obstacles like buildings and trees. This makes them an ideal choice for the deployment of mobile networks, especially in areas where infrastructure is a challenge. Sub-6 GHz bands are also less susceptible to interference, improving connection quality. In terms of capacity, these frequencies can support a significant number of devices connected simultaneously, which is essential in an increasingly interconnected world. In summary, the Sub-6 GHz band is fundamental for the effective deployment of mobile networks, balancing the need for speed with coverage and reliability.
