Detailed explanation-1: -5. Which of the following is a universally adopted shape of cell? Explanation: Hexagonal cell shape is a simplistic model of radio coverage for each base station. It has been universally adopted since the hexagon permits easy and manageable analysis of a cellular system.
Detailed explanation-2: -What is the main reason to adopt hexagon shape in comparison to square and triangle? Explanation: For a given distance between the center of a polygon and its farthest perimeter points, the hexagon has the largest area. Thus, by using the hexagon geometry, the fewest number of cells can cover a geographic region.
Detailed explanation-3: -A hexagon is a tessellating cell shape in that cells can be laid next to each other with no overlap; therefore, they can cover the entire geographical region without any gaps. This approximation is frequently employed in planning and analysis of cellular networks.
Detailed explanation-4: -When planning a cellular network, operators typically allocate different frequency bands or channels to adjacent cells so that interference is reduced even when the coverage areas overlap slightly. In this way, cells can be grouped together in what is termed a cluster.
Detailed explanation-5: -The basic geographic unit of a cellular system is a cell that conceptually has a hexagonal shape.
