Now-a-days most of the worlds population has a cell phone of some kind. Everyone with a cell phone is able to send anything like a text message or a picture and they are able to call anyone in the world whenever they want. Have you ever wondered what cell phones have that make that possible? The only thing that most people know is that there are cell towers all over the place but aside from that does anyone know what actually makes it all work?
For starters what is a cell tower? A cell tower (cell site) is a cellular-enabled mobile devise tower that has an antennae or other electronic communications equipment on it. They are usually on the top of radios, towers, or other raised structures to pass communication through the cellular network which allows your cell phone to function. With the cordless handsets, they connect to what is called a base station wirelessly. This is what allows you to talk to your friend in another area while still be connected to the wires of the public switched telephone network, or PSTN for short. When it comes to their main working principles, both a cellular tower and base station that allows both data and voice services for an iPhone or Android are much more alike than you probably think. These towers are mainly built to cover a wider geographic area.
When it comes to a cell tower and what they do, their main job is to elevate antennae to receive and transmit radio frequency (RF) signals not just form mobile phones but from other devices as well. In order to cover a targeted cell area, the engineers need to ensure that the antennae’s are tall enough so more often than not cell towers are anywhere between 50 to 200 feet tall. These towers are able to be standalone structures like steel poles or lattice frame and they are able to be affixed to other structures. With the latter category, the cell towers are more often than not are attached to things like tunnels, buildings, traffic lights, bridges, and even billboards.
The working range that cell towers have is all defined as the range that mobile devices that are able to connect to a reliable cell tower. But one thing you should understand is that this range is not set in stone. It all depends on sever different factors like
1. The antenna’s height
2. The frequency of the signal in use
3. the power of the transmitter
4. The weather conditions around the cell tower
5. Directional characteristics of the site
6. Reflection of radio energy by nearby buildings
7. The data rate of the subscribers mobile device.
