Many people use the internet every day via smartphone, laptop or tablet without ever thinking about how data can move from one device to another. When opening a website, sending a message, or watching a video, everything feels instantaneous without any visible cables connected to the device.

This often raises the question, does the internet really run without cables? The answer is not entirely. Even though the devices used are connected wirelessly, most internet networks in the world still rely on high-speed cables.
This article discusses how the internet can work even if the user does not see the cable directly.
The Internet Is A Very Large Network
The internet is a network that connects billions of devices throughout the world. Every time you access a website or application, the device will send and receive data over the network.
The data moves from one device to another through various paths until it finally reaches its destination.
Why don't smartphones use cables?
Smartphones utilize wireless technology such as Wi-Fi or 4G and 5G cellular networks.
When using Wi-Fi, data is sent via radio waves between the smartphone and the router. If using a cellular network, data is sent via radio waves to the nearest BTS tower.
Because it uses radio signals, users do not need to connect cables directly to the device.
Behind Wi-Fi There Are Still Cables
Even though the smartphone is connected via Wi-Fi, the router used is usually still connected to the internet using a fiber optic cable or other type of network cable.
This means that the wireless connection only occurs over a short distance between the device and the router.
The Role of Fiber Optic Cables
Most of the world's internet traffic is sent via fiber optic cables that stretch across land and the seabed.
This cable is capable of sending data using light at very high speeds so it can connect various countries throughout the world.
Why Not Just Use Satellites?
Satellites are used to provide internet access in certain areas, especially areas that are difficult to reach by cable networks.

However, the majority of global internet traffic still passes through fiber optic cables because they have greater capacity, higher speeds and lower latency.
How Does Data Get to the Website?
When a user opens a website, the device will send a request to the server where the website is located.
The request passes through the router, internet provider network, various other network devices, until it finally arrives at the server. After processing, the server sends the data back to the user's device in a very short time.
Why Does the Internet Feel So Fast?
Internet speed is influenced by many factors, such as network quality, fiber optic capacity, router technology, and the infrastructure owned by the internet service provider.
Technological developments make the process of sending data faster so that users can enjoy various digital services more comfortably.
Difference between Wi-Fi and Internet
Many people think Wi-Fi and the internet are the same thing, but they are different.
Wi-Fi is a technology that connects devices to a router without cables, while the internet is a global network that connects various devices and servers around the world.
Will the Internet Be Completely Cableless?
In the near future, the answer is likely no. Even though wireless technology continues to develop, fiber optic cables are still the backbone of the internet because they are capable of sending very large amounts of data stably.
Wireless technology and wired networks actually complement each other so that users can enjoy fast and reliable internet connections.
