Why so .. the question is not whether all this time we know if that Hp (handphone) is equal to a mobile phone? turns out the answer is that HP (mobile) is called (phone) mobile phone because it works by relying on signals emitted from a transmitter with a certain frequency. To divide the area so that there is an equal frequency in the area then a region or city is divided into such a wedge-shaped slices are described as hexagonal or called cells (cell). Each cell can have a frequency of 800 and has a coverage range of about 26 kilometers square. Each cell has a tower and a small building containing the equipment. When we're walking with driving a vehicle, the signal will be emitted from cell to cell by a tower or towers of each cell.
