Should Public Spaces Block Phone Signals?

Mal Fletcher on BBC Radio

The average Brit is now spending 25 hours per week on the internet, due in part to the use of smartphones.

One British pub is now using a Faraday cage device to block all mobile phone signals, to encourage people to relate more to each other and, according to the owner, "have more fun".

Is this a good idea? Should more public spaces incorporate blocks of this kind?

Social commentator and futurist Mal Fletcher says yes - and his reasons are intriguing. Here he speaks with BBC radio's Mike Parr.
