Copper/Fibre/WiFi network differences explained (Simply!)

If you are looking at upgrading, extending or installing a network at your premises then you'll likely be considering one of three methods of connection. Either read on or watch the short video for an explanation.

Copper Cable (typically called Cat5/Cat6):

Copper cable is most often used on runs under 100m. You'll likely have heard the terms Cat5, Cat6 etc. This relates to the network speeds the cable can handle. The discussion over network cable types and what should be used where is a whole different topic and quite honestly more than you need to know here.

We always suggest using fixed cabling wherever possible. It is stable and secure. Even in residential properties we'd advocate using fixed cabling for any fixed equipment such as TVs, computers etc.

Fibre Cable:

Fibre cable is fantastic for transmitting vast amounts of data over long distances. As a rule of thumb if you need to transmit a substantial amount of data over more than 100m then fibre is often the way to go.

Again, being fixed cabling, it is quite secure and not subject to any environmental issues you might have with antenna on a point to point (PTP) connection. However, installing fibre isn't cheap. Fibre cables are usually ordered pre-terminated and to a certain length.

Advantages:

• Fast data transfer

• Can handle significant amounts of data

• Great over longer distances (100m+)

Disadvantages:

• Expensive compared to copper/PTP (wireless)

• If it gets damaged it is expensive to repair/replace

WiFi:

WiFi is fantastically versatile and great for any mobile devices. Its almost expected that most premises have a WiFi connection.

If you have multiple people/devices needing to access your network at any one time then WiFi is excellent. But it needs careful design to work efficiently in a workplace or large site. Many factors can affect how well WiFi networks perform including:

• The construction/fabric of buildings

• How many other WiFi networks are in the vicinity

• How many users need to be able to connect at the same time

• How much data needs to be transmitted

• How many different networks you need to have in place (e.g. guest/hidden networks)

WiFi networks need to be designed properly including mapping areas and identifying building materials and other obstacles.

Our takeaways:

• Don't just think short term with your network, look at the bigger picture, start with a solid base design that can be expanded

• Don't underestimate the speed/bandwidth and coverage you will need

• Always try to use wired/fixed connections for fixed equipment

• Keep WiFi for temporary connections or mobile equipment/devices
