LAN
A local area network within a single location that connects computers, servers, printers, and other equipment.
What does it mean LAN?
LAN (Local Area Network) is a network within an office, business building, or production facility. It consists of switches, cables, Wi-Fi access points, and a firewall.
A modern business LAN is segmented into multiple VLANs: office, servers, guests, IP telephony, and production devices are separated, and the traffic between them is controlled.
LAN quality directly impacts work speed — a slow network manifests as slow applications, even if the servers are running flawlessly.
Practical examples
A company with two floors uses Power over Ethernet (PoE) switches for phones and access points, and a separate VLAN for guest Wi-Fi.
Business relevance
A poorly planned LAN is a common but overlooked cause of problems: interruptions, slowness, and an inability to control who accesses what.
Common mistakes
The most common mistakes are unsegmented networks where guests can reach servers, unmanaged switches without control, and non-existent documentation.

Frequently asked questions
- When do we need managed switches?
- As soon as you need segmentation, control, or Power over Ethernet for devices.
- Is Wi-Fi part of the LAN?
- Yes, wireless access is an extension of the local network and must follow the same security rules.
- How often should network equipment be renovated?
- Generally every five to seven years or at the end of the manufacturer's support life.
