Local Area Network (LAN)

Every LAN infrastructure consists of wired or wireless connections using hubs or switches. We design, plan and implement LANs using wired and wireless technologies where appropriate. We can also troubleshoot your existing set-up, drawing on a number of LAN surveying applications.

The Local Area Network (LAN) is by far the most common type of data network. As the name suggests, a LAN serves a local area (typically the area of a floor of a building, but in some cases spanning large distances). Typical installations are in industrial plants, office buildings, education or similar locations. In these locations, it is feasible for the owning organisation to install high quality, high-speed communication links interconnecting nodes. Typical data transmission speeds are one to 100 Mbps.

In summary a LAN is a communications network which is:

• local (i.e. one building or group of buildings)
• controlled by one administrative authority
• assumes other users of the LAN are trusted
• usually high speed and is always shared

LANs allow users to share resources on computers within an organisation, and may be used to provide a shared access to remote organisations through a router.
