What is a LAN? A comprehensive guide

You encounter LANs more often than you think – if only when all your home devices have Wi-Fi access or several computers in the office use the same printer. It’s the local area network that makes everything work together.

You don’t have to be an IT specialist to understand how it works. In this text, we will explain in simple terms what a LAN actually is and how ITH can help you set it up. Zero unnecessary technical buzzwords, just simple explanations!

LAN – basic information

A LAN ( local area network) is otherwise known as a local area network, which connects devices located in a relatively small area (home, office or campus). With a LAN, you can connect computers, printers, servers and other devices that share network resources and enable data exchange.

But today, such an internal network alone is often not enough. Companies are growing, changing, and their needs are evolving too. We need more than just connecting devices “under one roof.” We want a whole, integrated system that is secure and perfectly tailored to our requirements.

And this is where it comes in ITH. A company created by true enthusiasts in the telecommunications industry. People who know very well that in today’s world just connecting to the Internet is only the beginning. “Network is not everything” – is our motto!

ITH does not serve you off-the-shelf, off-the-shelf solutions, the kind “for everyone”. We sit down, listen to your needs and design LAN systems tailored to your business. Fully scalable and compliant with current regulations. Whether your company operates from a single location or you have several offices scattered across different cities, a well-designed LAN is the backbone of efficient and secure communications. And with ITH, you can rest assured, because that backbone will be really solid!

Types of LANs – wired and wireless

The easiest way to divide them into those “on cable” (Ethernet) and those “without cable” (Wi-Fi). In many offices you will find both solutions side by side. Computers that stand still and need a very stable and fast connection are usually hooked up with a cable. Instead, laptops, phones or tablets that need to be mobile use Wi-Fi – this gives them the freedom to move around. There are also “hybrid networks”, which cleverly combine the two worlds, selecting a solution depending on what is needed at the time.

It is this approach – flexible, tailored to the company’s daily realities – that is the foundation of the ITH team’s work. It’s not about making sure everything is “on the wire” or just “on Wi-Fi,” but that the network really supports people in their work. ITH can design and implement a network environment that not only works, but also keeps up with the pace of the company – without unnecessary downtime, with an eye on the future.

LAN security – why is it so important?

A LAN is not just cables and hardware – it’s a place where important company data “flows” every day: documents, emails, access to systems or customer information. Therefore, taking care of wireless and wired network security is essential.

You don’t have to imagine hackers making an intentional attack on company data. Sometimes all it takes is for someone to accidentally plug an unknown device into the network or accidentally share access data for problems to begin. And the consequences? They can be really nasty – from downtime at work, to loss of important data, to serious financial losses and a problem with the company’s reputation.

That’s why it’s a good idea to have solutions on hand that not only provide a fast connection, but also allow you to control who and what is doing on your network. We’re talking about checking devices, zoning your network or regularly updating hardware and software. That way, even with a growing company, you can rest easy knowing that your network is secure.

That’s why ITH Net offers comprehensive solutions to enhance LAN security, such as:

• firewall configuration,

• Advanced protection systems against network attacks,

• Regular software updates for routers and network devices,

• Training and technical support for companies.

Wired and wireless networks: this is what you need to know!

At ITH, we also design and create other networks, not just LANs. We carry out orders for Wireless LAN, or WLAN. LAN and WLAN are not quite the same thing, although they are very closely related and often complement each other.

How to understand it?

• Every WLAN is also a LAN (because it is local).

• Not every LAN is a WLAN, because a LAN can also be a wired (i.e., by cable).
