Steve Tyler put silver foil in the walls and copper wire mesh in the ceiling of the Gin Tub in Hove.

He said he was tired of people coming in and not socialising with each other or with anyone else in the building.

"I've seen it progressively get worse and worse and I thought, 'I want to stop this,'" Mr Tyler told BBC Sussex.

"I want people to socialise with the people they are with, rather than the people they are not with.

"I took the bold decision by not blocking the signal with a jammer but doing as best as I could with a Faraday cage and make people talk to each other, and to be honest it has worked very well.

"I had quite a lot of copper mesh and thought, 'I could put this in the ceiling.'

"I was mucking about with it to see if it would block a signal, and it does when you put your phone in it."

Mr Tyler plans to have a mobile phone area outside similar to a smoking area.
