Have you ever wondered why your phone works perfectly in some areas but struggles in others? And the answer lies in spectrum bands. These are the invisible highways that carry your data. And not all bands are the same. Some go farther while others handle more traffic. Let's break it down. is divided into different frequency bands and each having certain unique strengths. Operators mix and match them to deliver the best performance and here are the key widely used bands such as band 8 which is 900 megahertz band. It is like a coverage provided by these bands where it travels longer distances and and it's greater for covering rural areas or suburban areas. But there is certain limitation with band 8 because the bandwidth is limited to 35 megahertz only, so it can get congested easily. Even within 35 megahertz, if there are more telecom operators and a regulator has to allocate this particular bandwidth of 35 megahertz across those operators, it will further come down and there is a high…
