We have a varied collection of mobile industry news stories in this week's podcast, including new rules affecting airline passengers with smartphones.

We also talk about BlackBerry giving up its European research centre, Vodafone installing fibre-optic broadband, Samsung's profits, spending on mobile advertising, M2M adoption and WiFi on trains.

UK telecoms regulator Ofcom has agreed to make radio spectrum available for transport operators to offer faster broadband connections to passengers on aircraft, boats, railway trains and coaches.

Each vehicle could receive a data connection of around 50Mbit/sec, providing more than 10Mbps via WiFi to an individual passenger.

This week's podcast starts with talk about money, as Google buys smart thermostat company Nest Labs while O2 UK closes its mobile Wallet product.

We're also looking at the decline of SMS text messaging in the UK, the end of the Cash4phones recycling business, an alleged security breach that wasn't what it seemed, mobile service on the Channel tunnel and the growth of 4G.

Farewell for another year, dear old International CES. The Las Vegas-based consumer electronics show is but a fading memory as the mobile industry starts preparing for next month’s GSMA Mobile World Congress in Barcelona.

However, what happened in Vegas doesn’t stay in Vegas.

Eurotunnel has signed a 10-year agreement with EE and Vodafone that’ll make mobile phone services available to Eurostar and Le Shuttle passengers travelling from the UK to France.

A similar deal came into operation last year with French networks providing mobile coverage in the ‘South Tunnel’ that carries travellers from France to the UK.
