Before delving into the specifics of coax cables, it’s essential to understand how your Internet connection works, especially if you’re considering setting up or upgrading your home network.
How Does Internet Work?
At its core, internet connectivity involves multiple layers of technology, including:
-
MODULATION OF SIGNALS: Internet data is sent via modulated signals. This can be done through various means, including coiled copper wires, fiber optics, and coaxial cables.
-
ROUTER AND MODEM: Your home network consists of a modem that connects to the internet service provider (ISP) and a router that distributes the internet connection wirelessly to your devices.
Understanding the Roles of Modems and Routers
A modem converts data from your ISP into a format that can travel through your home network, and a router creates a local network, usually through WiFi.
-
Modem: You need to connect your modem to your ISP’s cable (which could be coax, fiber, or DSL, depending on your internet plan).
-
Router: This device can create a wireless network that does not require physical cables to connect each device.
Now that we have a grasp of the basics, let’s dive deeper into the role of coax cables, particularly when setting up WiFi connections.
What is a Coax Cable?
A coaxial cable, often abbreviated as coax, is primarily used to transmit cable television signals and broadband Internet. It consists of:
- Inner conductor: A wire that carries the signal.
- Insulating layer: To prevent interference.
- Outer conductor: Typically made of metal foil or a braided mesh, it helps block interference from external sources.
- Protective outer layer: Usually made of a plastic coating to shield the internal components.
Coax cables are commonly used with cable internet and provide a stable and fast connection compared to their DSL counterparts.
