One of the biggest companies meeting the UK's demand for public WiFi is The Cloud, which has spent the last few years putting its network into thousands of venues.

In this programme we interview Vince Russell, managing director of The Cloud, to discover what the company's doing... and to see whether mobile operators should be worried.

According to a new survey from ABI Research, 73% of countries with 4G mobile services have seen the ‘price per megabyte’ of 4G data fall by an average of 30% in the past six months.

The lowest price for 4G data is currently in India, while the highest price - $67.80 (£43) for 5GB - is in the UAE.

A ‘solar superstorm’ could disrupt satellite navigation systems, electricity supplies and high-frequency radio communications in the UK - but the nation’s mobile phone networks should be largely unaffected.

That’s the message from the Royal Academy of Engineering, which has just published an in-depth assessment of the potential impacts of solar superstorms. These rare events - unlike other solar storms - occur every few hundred years.

Quarterly figures from Vodafone Group show service revenue declining by 2.6% year-on-year to £10.4 billion, despite data revenue increasing by 12.8%. In the UK, service revenue was down 5.2%.

The company is aiming to cut £300 million from its costs during the next financial year.

Sony’s latest quarterly results show the electronics company making a loss of 10.8 billion yen (£73.3 million) for the three months until 31st December 2012, although that’s considerably less than the 159 billion yen loss from the same quarter a year before.

Sales and operating revenue rose 6.9% year-on-year to ¥1,948 billion, helped by the takeover of Sony Mobile.
