One of the key advantages of 3G cell towers was that they could cover immense territory with relatively few cells. This is because the network did not require as much bandwidth, meaning networks had to deploy fewer cells. When technology progressed to 4G networks, the cells were producing more bandwidth, meaning the coverage radius of each cell was smaller. People may have noticed that their coverage may drop more often than on their 3G network. As the 5G network gets rolled out, this trend will continue. More cell towers will be required to produce this immense bandwidth because the cells are not able to cover as much space as a 3G or 4G cell. Because more cells will need to be rolled out, 5G users should expect that their coverage may not be as widespread at first.
