🏠 Planning a modern home? Don't forget about the LAN! A stable internet connection is no longer a luxury, but a necessity these days. Learn how to plan and implement a home LAN installation that will provide high-speed internet in every room. We'll advise you on which cables to choose, where to place RJ45 sockets, and how to set up a central distribution point. Read our guide and build a network that will operate reliably for years to come!
Installing a LAN network at home - how to plan a modern wired network?
With more and more devices connecting to the internet, from computers and smart TVs to alarm systems and IP cameras, a home LAN is becoming the foundation of any modern installation. A wired connection is still the most stable, fast, and secure form of data transfer, so it's worth ensuring it's professionally installed.

What is a LAN and why is it worth having one at home?
A LAN (Local Area Network) is a local computer network in which devices are connected via Ethernet cables. Despite the popularity of Wi-Fi, a LAN offers:
-
higher data transfer speed (up to 10 Gbit/s),
-
lower latency (ping),
-
resistance to interference,
-
greater security.
LAN is an ideal solution for, among others:
-
players and streamers,
-
people working remotely,
-
owners of NAS, IP cameras, Smart TV,
-
homes with smart home systems.
How to plan a LAN installation at home?
1. Determine the number and location of network points
It is best to plan at least 1-2 LAN sockets in each room - especially where there will be:
-
computers,
-
televisions,
-
consoles,
-
network printers,
-
alarm control panels.

2. Choose the right Ethernet cable
For a single-family home, the following are recommended:
-
Category 6 cables - up to 1 Gbit/s (often sufficient),
-
category 6a or 7 - if you are planning 10 Gbit/s or a NAS server.
3. Provide a central point for the network – a telecommunications cabinet
All cables should come together in one place - preferably in a multimedia RACK cabinet , where you can place:
-
router,
-
network switch,
-
possibly a patch panel,
-
safety devices (UPS, surge protectors).

What will you need to create a LAN?
To perform a stable and professional network installation at home, prepare:
-
LAN cables (min. Cat. 6, shielded U/FTP or S/FTP),
-
RJ45 sockets – flush-mounted or surface-mounted,
-
Installation boxes – with space for cables,
-
Patch panels - with more points,
-
Network switch - splitting the signal from the router,
-
Telecommunication cabinet - with ventilation and power supply,
-
Cable holders and guides - for aesthetic cable management.
Practical assembly tips
- Avoid running LAN cables in parallel with 230V cables - this may cause interference.
- Use cable channels - this will facilitate future modernization.
- Leave a spare wire in the boxes - at least 20-30 cm.
- Test each line with a LAN tester - especially before plastering.
- Modular trunking allows you to freely add additional RJ-45 sockets
- The use of channels with double-sided tape allows for clean installation without unnecessary dust.

The most common errors in a home LAN
-
Too few LAN points - difficult to add them later.
-
Low category cables - limit throughput.
-
No telecommunications cabinet - cable chaos at the router.
-
Sockets mounted too low - vulnerable to damage.
Summary
A home LAN is an investment in connection stability and speed. Unlike Wi-Fi, it ensures there will be no interference or speed drops, regardless of the number of connected devices. If you're planning a new home or renovation, consider LAN during the electrical design phase.
