Tep Wireless, which rents 3G personal WiFi hotspots and smartphones, has pointed out that “wireless access points and 3G hubs” are banned from venues for the London 2012 Olympic and Paralympic Games.

The London 2012 rules also say that smartphones are permitted inside venues but must not be used as wireless access points to connect multiple devices.

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.

The entire fleet of 47 trains operated by Translink NI Railways in Northern Ireland is being equipped with free WiFi.

Nomad Digital, which has already implemented wireless internet access on Amtrak and Virgin Trains, expects the full roll-out to be completed by the autumn.

greentomatocars, which was established in 2006 as London’s first green minicab company, is now offering free WiFi in all its vehicles. It’s thought to be the first passenger car company in Europe to install a mobile hotspot service.

The company operates 300 Toyota Prius hybrid cars as well as people carriers and executive vehicles in the capital.

A new report from telecoms consulting firm BWCS shows that the UK has broadband wireless services on more trains than any other European country.

There are now 2,000 WiFi-equipped railway carriages in the UK, putting the country ahead of its closest rivals Germany (with 911 carriages) and Italy (with 995 carriages). France is even further behind with just 416 WiFi carriages.
