What Is Macrocell?

The macrocell is a giant cell. No, not a cell that is blown up in proportion. You know what we mean: the one that covers an entire neighborhood or city. It's called a macrocell because it's larger than other cells, and the coverage area is more significant—but it's not as small as microcells (which cover only a small size) or femtocells (which are used to connect single users). Macrocells simultaneously communicate their signals in all directions, so anyone within their range can receive them. It means they don't need to adjust their output power (and thus waste energy) depending on where people are located within the network. The downside of this approach is that you can't pick and choose who receives your signal—you're broadcasting over everyone within range, whether they want it or not! Macrocells are giant, powerful cells in cellular networks. They're like the big brother of the little cells you're used to—they can be as much as ten times bigger than the little ones. Macrocells must be mounted on a mast or other structure at least 30 meters tall to see over any buildings or trees in their area. The cell will also need an antenna with a wide coverage range, up to 30 degrees from its axis. The height of a macro cell is essential because it determines how far away from it users can get before losing signal strength. The higher it is, the farther away users can be before dropping off altogether. This makes sense if you think about it: if someone were standing directly under a cell tower, they'd have pretty good reception—but if they were standing on top of another building just next door (like across the street), they'd probably have lousy reception or none at all!
