Telecommunication towers are the backbone of modern communication networks. They ensure you can call, access the internet, or send messages without any disruption. These towers are installed all over the world and form an intricate communications network that makes everything from watching videos to conferencing with clients from a different country possible. Humans rely on towers every day, but most people don’t know how they work. Here’s a brief insight into how the system works:
The Structure of a Tower
A telecommunication tower is a tall structure made from steel, aluminium, or wood. The height and design of these structures vary, but they all serve the same purpose. They have one or more antennas mounted at the top that receive and transport telecommunication signals from one station to another.
These structures are connected through hardwires buried underground. The wires power the towers and also handle wired communication. A telecommunication network is vast and intricate, spanning almost the entire country. Organizations have managed to set up towers in even some remote areas of Canada, which helps maintain proper communication.
Telecommunications towers with cellular antennas mounted at the top are also called cell sites. Every cell site covers a fixed area, which is known as a cell. Its primary tower handles all mobile communications within a cell. Cells can overlap but are mostly set up strategically to provide maximum coverage. Overlaps ensure there are no gaps in cellular coverage.
Without a properly functioning cell site, there’s no way for people to communicate using their mobile phones. That’s why companies work hard to maintain these sites and ensure there’s no disruption in service.
Range of Towers and Cell Phones
All telecommunications towers and mobile phones have a limited range. Your device must be within a range of a tower for the service to work effectively. A site’s range depends on its structure, placement, location, geography, and obstructions like tall buildings around it. A signal weakens or bounces back when it encounters too many obstacles.
That’s one of the reasons why most telecommunications towers are tall or located on elevated grounds. This ensures the signal isn’t interrupted by any obstacle, and people can communicate without problems.
Towers are often placed on top of tall buildings in densely populated urban landscapes. For example, the Empire State Building in New York has several telecommunication devices placed on top of it because it is one of the tallest buildings in the city.
Telecommunication companies often consider the surrounding environment carefully before picking a location for tower installation. Their goal is to make sure all signals between towers and cell phones travel freely.
How Cell Phones Communicate with Sites
When you call someone, your cell phone sends a signal to the nearest tower. This signal travels down to the hardwire network underground and is transported to a destination tower that’s closest to your call recipient. This signal then travels from that cell site’s underground network up the tower and into the cellular devices.
These devices broadcast the signal until it reaches a recipient’s phone, allowing you to communicate with them. As you can see, the communication is fairly straightforward, and everything happens in a fraction of a second, regardless of the distance between you.
Cell Phone Carriers
Your phone communicates with a tower that’s in your carrier’s network. It won’t send signals to the closest cell site, but to a nearby cell site that has your carrier’s equipment. Major service providers have wide-spread networks consisting of thousands of telecommunication towers and can provide more comprehensive coverage to cell phone users.
A strong telecommunications network allows people to call, message, or browse the internet without any disruption.
