Google launches Nexus S phone in UK and US

Google has made its second bid for a slice of the mobile phone market, with the launch of its Nexus S phone, reports BBC News.

The Samsung-built device comes less than 12 months after the launch of the firm's Nexus One, built by HTC, which failed to win over many consumers.

The Nexus S will initially be launched in the UK and US, and will be available "from the end of the month".

It is the first phone to feature the latest version of Google's Android operating system known as Gingerbread.

It also comes with new hardware such as Near Field Communications (NFC).

This short-range wireless technology is used predominantly in places like Japan and allows people to use their phone as a travel ticket, make small payments and scan their phone over adverts, for example, to get more information about a product.

"NFC allows the Nexus S to read smart objects" said David Burke of Google's mobile division.

These objects must have a small, unpowered NFC chip in them that is activated when the phone is held near.

"When you put the phone on top, it energises the circuit," explained Mr Burke. "It can echo information back to the phone and the phone can send information to the chip.

"So, you can swipe a movie poster and watch the trailer automatically," he said.

NFC is a growing trend in mobiles and will start to become more pervasive in the New Year, said Shaun Collins, managing director of research firm CCS Insight.

"NFC is going to be the technology of 2011, in my opinion," he told BBC News. "Most of the BlackBerries will have it and a big swathe of mid to high-level Nokias will have it."

The next version of the iPhone is also rumoured to contain the technology.
