There are so many options to choose from when it comes to internet service providers and the many different ways to connect to the internet. Today it seems like we need a good internet connection for everything from our smartphone and computing devices to our home security devices and appliances. 

When it comes to choosing an internet connection for your home, there are a few different options available. Two of the most popular choices are fibre optic internet and WiFi. But what is the difference between these two types of connections?

What is Fibre Optic Internet?

Fibre optic internet, also known as fibre broadband, is a type of internet connection that uses fibre optic cables to deliver high-speed internet to homes and businesses. Fibre optic cables are made of thin strands of glass or plastic that are capable of transmitting data at high speeds. Fibre optic internet is the fastest type of internet available, and it is becoming increasingly popular as more people rely on the internet for work, school, and entertainment.

Benefits of Fibre optic internet may include: 

What is WIFI Internet?

WIFI internet is a wireless type of internet connection that uses radio waves to connect your devices to the internet.The radio signals are sent from a wireless router to a device which then translates the signals into data you can see and use on the device. The connected device then transmits a radio signal back to the router, which connects to the internet via a wire or cable. The WIFI router is directly connected to your internet modem.  Because a WIFI network is wireless, multiple devices can be connected to the router at the same time.

Why is business internet so expensive?

In one of our previous blogs – Why Business Fibre Is Still So Expensive in South Africa we looked at the technical aspects of why Business Fibre is more expensive than Home Fibre. In this blog we saw that Business Fibre is more expensive due the physical hardware required to provide a stable business internet connection. 

Business Internet packages provide more features than home internet packages which may include increased bandwidth, speed, scalability, dedicated customer support, reduced risk or down time and so much more. Business internet packages focus on providing their customers with reliable internet. 

From the above information we can see that Fibre Optic Internet is a cabled internet that is physically installed at a specific location. WIFI Internet uses radio signals to wirelessly transmit data.

Which should you choose for your home?

We have seen the main differences between the 2 types of internet connection. When deciding which internet connection is right for your home there are a few questions you need to ask before deciding. 

  • What internet speed do I require?
  • How often will I be using the internet?
  • Do I need a fixed plan or uncapped plan? 
  • How many devices and people will log into the internet?
  • Is there fibre optic cable in my area? 
  • How strong is the internet signal in my area?
  • What equipment is required? 
  • What is my budget?

Are there other internet alternatives?

Satellite, DSL, dial up, and cellular data plans are all alternatives to WIFI and fibre optic internet. Mobile phone companies offer cellular data plans on SIM cards, which can be used directly with a laptop, dongle or wireless router. They all have their own pros and cons that you should consider before choosing one for your home or business.


So, there you have it — the key differences between fibre optic internet and WiFi. Both have their pros and cons, but ultimately it comes down to what you need from your internet connection. If you need speed and reliability, fibre optic internet connection is the way to go. However, if you’re looking for a more affordable option, WiFi might be a better choice for your home.
