What does 5G mean for the future of Wifi? We talk to Wifinity’s CTO to find out

With 5G launching in the UK this summer, more and more Brits will be getting faster mobile broadband.

But the burning question for property developers is, ‘will this replace the need for superfast Wifi in my development?’

We asked Wifinity’s Chief Technology Officer, Paul Scahill for his take on how 5G will impact residential property developments.

Do I still need to install a high-speed service in my developments if everything is going 5G in the future?

Yes, your residents will still need in-home broadband. The current consensus is that 5G will not be able to support everything, everywhere in the future. 

5G has still not been fully defined or rolled out yet so residents will need an in-home connection to support their smart home and leisure activities. 

Currently, fixed line full fibre solutions offer gigabit speeds in and around the home. That home connection fully supports your residents needs – and that won’t be changing anytime soon.  

Will all devices use 5G?

No, there will be gaps in the 5G network which will be filled by other technologies as is the case today. Just think about your average smart home setup now. It’s probably either WiFi or Bluetooth enabled.

Continued innovations in WiFi, Bluetooth and the latest WiGig offering will continue to play a major role in the home environment.

Will 5G work well in a development?

Potentially not. Some new build developments can resemble a faraday cage, which can block the 5G frequency. Having a fibre optic cable in the building could be essential to compensate for this. 

And it’s not just new properties, the physical structure of older properties can also cause problems for the 5G frequency.

How does a residential property developer future-proof a building to enable 5G?

Depending on the development type, aim to get fibre optic cable specified in a building that can be used by different operators. This also makes sure the development can react to future requirements which are not fully defined today.  Designing a specification of pits, power, ducting and fibre breakout points at regular locations from the start will future-proof the development. 

What is the most innovative ‘internet of things’ device that will benefit from 5G?

Currently there is a lot of hype about how 5G devices will be used… but the best ones are those that require high-speed internet no matter where you are.

A great example would be home doctor and dementia care products. These have the power to revolutionise healthcare and save our NHS a huge amount of money.
