The first mobile phones fitted with Google's Android software platform made their debut at an industry trade show on Monday, a milestone for the Internet giant as it looks to dominate the wireless world.
A handful of chip makers -- ARM, Marvell, Qualcomm, NEC, Texas Instruments and ST Microelectronics -- showed off prototype handsets at the Mobile World Congress in Barcelona.
Google launched Android last year, hoping to establish its software as the standard operating system for mobile phones and to improve the quality of Web-browsing for handset users.
"It's definitely very promising," said Carolina Milanesi, an analyst at the technology research firm Gartner.
"This means that we should be on track to see commercial devices in the second half of 2008," she said.
The idea is that Android will lead to radically improved functionality, notably for Web browsing, meaning more people will use their mobile phones for Internet surfing and other applications.
Internet use on mobile phones can be a frustrating experience, with clunky software and slow download speeds.
"There are few phones that provide a compelling Web experience," Google spokesman Barry Schnitt said. "As people use the web more, they'll use Google more and we'll be able to sell more relevant advertising."
Android is being developed by a coalition of 30 handset manufacturers, chip makers and software groups and is based on open-source code, meaning programmers are able to build compatible applications for free.
"The future ability of Android is exciting because it's open-source so it allows developers to come up with the next killer application," said a spokesman for US chip maker Texas Instruments, which demonstrated Android software in a prototype phone.
The Apple iPhone, for example, runs on Apple software and uses Apple applications, while an Android-enabled phone would incorporate applications from any number of developers.
But Google software faces fierce competition from the world's biggest mobile phone maker, Nokia, and its Symbian system.
US software giant Microsoft also has a Windows system for mobiles and a separate consortium is working on an open-source Linux solution.
Android was on display for the first time in only prototype phones. The first handset for consumers from either Taiwan's HTC or US group Motorola is expected in the second half of this year.
Google announced the "Open Handset Alliance" in November last year to develop Android, including China Mobile, HTC, Intel, Motorola, Qualcomm, T-Mobile, Telefonica, LG and eBay.
Milanesi said that "the road between a prototype and commercial handset is a long one" and that the ultimate test of Android's success would be how easily applications could be used.
"It should have everything that we see on the PC, not just shrunk down to work on a mobile phone, but really being optimized for a mobile phone," she said.
The interest in a new software platform from Google also stems from the company's desire to establish its brand in emerging markets.

Japanese Prime Minister Sanae Takaichi yesterday lavished US President Donald Trump with praise and vows of a “golden age” of ties on his visit to Tokyo, before inking a deal with Washington aimed at securing critical minerals. Takaichi — Japan’s first female prime minister — pulled out all the stops for Trump in her opening test on the international stage and even announced that she would nominate him for a Nobel Peace Prize, the White House said. Trump has become increasingly focused on the Nobel since his return to power in January and claims to have ended several conflicts around the world,

UKRAINE, NVIDIA: The US leader said the subject of Russia’s war had come up ‘very strongly,’ while Jenson Huang was hoping that the conversation was good Chinese President Xi Jinping (習近平) and US President Donald Trump had differing takes following their meeting in Busan, South Korea, yesterday. Xi said that the two sides should complete follow-up work as soon as possible to deliver tangible results that would provide “peace of mind” to China, the US and the rest of the world, while Trump hailed the “great success” of the talks. The two discussed trade, including a deal to reduce tariffs slapped on China for its role in the fentanyl trade, as well as cooperation in ending the war in Ukraine, among other issues, but they did not mention

REASSURANCE: The US said Taiwan’s interests would not be harmed during the talk and that it remains steadfast in its support for the nation, the foreign minister said US President Donald Trump on Friday said he would bring up Taiwan with Chinese President Xi Jinping (習近平) during a meeting on the sidelines of the APEC Summit in South Korea this week. “I will be talking about Taiwan [with Xi],” Trump told reporters before he departed for his trip to Asia, adding that he had “a lot of respect for Taiwan.” “We have a lot to talk about with President Xi, and he has a lot to talk about with us. I think we’ll have a good meeting,” Trump said. Taiwan has long been a contentious issue between the US and China.

GLOBAL PROJECT: Underseas cables ‘are the nervous system of democratic connectivity,’ which is under stress, Member of the European Parliament Rihards Kols said The government yesterday launched an initiative to promote global cooperation on improved security of undersea cables, following reported disruptions of such cables near Taiwan and around the world. The Management Initiative on International Undersea Cables aims to “bring together stakeholders, align standards, promote best practices and turn shared concerns into beneficial cooperation,” Minister of Foreign Affairs Lin Chia-lung (林佳龍) said at a seminar in Taipei. The project would be known as “RISK,” an acronym for risk mitigation, information sharing, systemic reform and knowledge building, he said at the seminar, titled “Taiwan-Europe Subsea Cable Security Cooperation Forum.” Taiwan sits at a vital junction on
