How Ethernet cables connect and power Local Area Networks
A quick guide to LAN connectivity
When it comes to building a reliable, high-speed network, Ethernet cabling remains the gold standard, but what exactly do these cables do and what types of devices do they connect?
Connecting devices within a LAN
Ethernet cables are used to connect devices within a Local Area Network (LAN) typically found within an office, warehouse, school or factory environment, where unlike Wi-Fi, which relies on radio signals, Ethernet uses physical cabling to create direct, stable links between devices.
The result is faster speeds, lower latency and greater reliability, which is especially important for organisations.
Some of the most common devices connected via ethernet include:
- Desktop and laptop PC’s: For reliable internet access, internal file sharing and secure data transfer.
- Routers and modems: To distribute your internet connections across the network.
- Network switches: To expand the number of connected devices and manage traffic efficiently.
- IP Phones and VoIP systems: For clear, interrupted voice communications.
- CCTV & security cameras: Particularly those using Power over Ethernet (PoE).
- Wireless Access Points: Extending Wi-Fi coverage, especially in larger buildings.
- Printers and servers: For centralised storage and shared office resources.
Why use Ethernet?
When devices are connected via Ethernet, they can directly and securely communicate with each other.
This is essential for tasks like ile sharing, printer access, IP telephony and surveillance.
It also reduces congestion on your wireless network and supports higher bandwidth applications, like Teams calls or large file transfers.
Many organisations are heavily reliant on robust Ethernet cabling and it is critical to their daily operations, as it is trusted for its durability, speed and ability to scale as organisations grow.
From small office set ups or large commercial sites, Ethernet cabling is the back bone of a fast and secure LAN.
By connecting key devices through structured cabling, you lay the foundation for a further-proof high performance network, one that supports everything from basic internet to cloud computing and smart technology.
