Just a few weeks ago WiFi was made available on a number of London Underground stations - yet mobile coverage still stops when you go down the escalator.

So why is it taking so long for us to get mobile phone service on the Tube?

For an insight into some of the challenges and the possible solutions I spoke to Ian Brown, CEO of Axell Wireless. The company is a leader when it comes to providing additional wireless coverage in confined spaces - from tunnels to sports stadiums - and is currently involved in the project to install mobile phone service on the Channel Tunnel.

It was a good week for technology stories hitting the mainstream news, thanks to the apparent appearance of a Higgs boson, Sir Alan Sugar’s YouView online TV service and football goal-line technology.

Mobile-related news hasn’t been quite so big, although plenty of well-known names have turned up in the headlines. What’s also been turning up – rather more than usual – is the presence of WiFi.

Microsoft started last week with news of an own-brand rival to the Apple iPad. The new Windows-based Microsoft Surface tablets will start to appear later this year, although full details of the specifications – including whether or not there’ll be cellular connectivity – remain unconfirmed.

Is there any product that offers as much potential for additional sales as the mobile phone?

When I visit a coffee shop to buy a coffee, I’m often asked “would you like any pastries or muffins with that?”

On the one occasion that I bought a new car, I was offered the option of paying extra for different colours, for floor mats and for a fancy stereo. When you buy a DVD player or a games console, it’s pretty obvious you’ll be paying extra for entertainment.

Yet, when you consider the variety of add-ons available in the mobile industry, I’d say smartphones were in a league of their own.

Oh, how cheerful we were last Monday. Apple previewed iOS6, which will bring mobile tickets (and 200 other new features) to the iPhone and iPad this autumn. Vodafone cut the cost of using your phone in Europe with its flat-rate £3-per-day EuroTraveller deal and a few days later Three came up with its own ‘unlimited’ European data roaming.

Yet by the end of the week there were fewer smiles in the mobile industry.
