Common 5G Questions and Answers

Fibre for business

From the advent of the mobile phone, there has been a supporting network which started with the first generation – 1G – and has evolved alongside cellular technology to the current network, 5G or the 5th generation cellular wireless.

Here are the most frequently asked questions surrounding the 5G network answers

Some of the biggest advantages of the 5G network include bigger channels, lower latency and the capability to connect many more devices. Here is a look at all you need to know about the 5G network.

Q: Why does 5G need fibre optic?

A: Using wireless transmitters, 5G will be able to transfer data to mobile devices, and many of these transmitters will connect to the internet through fibre optic cable. Fibre will allow you to enjoy the full experience of 5G which includes the provision of secure, scalable, reliable connectivity transmitting massive loads of data at enhanced speeds.

Q: How does 5G work?

A: This network, as with the current 4G LTE network, is OFDM (orthogonal frequency-division multiplexing)-based and operates on the same mobile networking principles. However, the new 5G NR (New Radio) air interface will enhance OFDM for more flexibility and scalability.

Q: Will 5G be better than fibre?

While the 5G network brings with it many benefits – particularly high speed – it will take some time before it can rival the existing fibre networks. Fibre will remain the predominant form of communication for the majority of businesses, but 5G will play an important role in the Internet of Things.

Q: Will 5G make WiFi obsolete?

A: Most expert believe that 5G and WiFi will continue to co-exist for the foreseeable future, with the two networks complementing each other rather than competing. Currently, WiFi – particularly fibre optic connectivity – provides the fastest, most affordable internet connection for home and office use.

Q: What is faster than fibre optic?

A: No wireless technology is faster than delivered connectivity, although wireless technology does require less infrastructure. 5G technology is also affected by weather and environmental issues, where fibre optic connections are not.

Q. What are the benefits of 5G?

A: As the latest mobile network support, 5G will allow for the connection of a wide variety of devices beneficial for personal and business use. The 5G network brings with it enhanced performance, efficiency and cost, effectively redefining industries from retail through to entertainment – and everything in between.

Q: What are some of the differences between 4G and 5G?

A: There are several differences between 4G and 5G, namely:

  • 5G is a unified platform and more capable than 4G
  • 5G uses spectrum better than 4G
  • 5G is faster than 4G
  • 5G has more capacity than 4G
  • 5G has lower latency than 4G

Q: What is a private 5G network?

An added benefit of the 5G network is the private 5G option or next generation Local Area Network (LAN). Using the 5G technology, a dedicated network can be created to offer unified connectivity, optimised services and secure communication.

Q: What are the disadvantages of 5G?

5G Fequency is interrupted by physical obstructions such as trees, towers, walls and buildings and the costs related to the development of 5G infrastructure or adaptations to existing cellular infrastructure will be high. While 5G might bring about real connectivity for the predominantly urban areas, those living in the rural settings will not necessarily benefit from the connection.
