I am still stuck with a pager along with my cellphone because the cellphone doesn't adequately filter calls and the pager is only for urgent calls when I don't answer the cell. T-Mobile USA, the fourth-largest mobile phone company in the United States, is preparing to launch a service this month that will allow people talking on their cell phones to seamlessly switch between T-mobile's cellular network and their home Wi-Fi networks. T-Mobile's new service, which will be the first of its kind in the United States, will be a test case for other operators also looking to deploy similar services. Sprint Nextel, through its joint venture with four major cable companies, is also looking into developing a similar service. And Cingular is testing a service in its labs. Carriers in Europe, such as Telecom Italia and Orange, have already said they will launch their services later this year, charging between 10 and 15 euros per month for unlimited calling from dual-mode Wi-Fi/cellular phones used in home networks. The business case for consumers in Europe is simple: The dual-mode services are much cheaper than current cell phone and landline rates. In the United States, where voice minutes are sold in buckets, Wi-Fi/cellular services could be a harder sell. That said, there are some compelling benefits for U.S. consumers. For example, cell phone users will be able to conserve voice minutes while talking on the Wi-Fi network, which could allow them to reduce their usage plans and reduce phone bills. They'll also get access to a higher speed network that allows them to download mobile content, like Web pages, music and games, much faster than they can even from a 3G wireless network. But analysts, such as Charles Golvin with Forrester Research, say that these services may not catch on with consumers until users see added functionality that they can't get on their regular cellular phones. "Just like with the voice over IP movement, people will be interested in converged Wi-Fi/cellular services at first based on price," he said. "But eventually it will become more about features." Tapping the advantages of IP Specifically, Wi-Fi-based phone services will allow consumers access to a whole slew of IP-enabled features, such as receiving voice mail from a Web portal, or being able to see whether friends on their buddy lists are available for phone calls. T-Mobile, which is using a standard technology developed for GSM networks called unlicensed mobile access, or UMA, is keeping details of its new service under wraps. "T-Mobile is interested in the replacement or displacement of landline minutes," a spokeswoman said in an e-mail. "We believe the future will be about leveraging diverse forms of radio access technology for our customers and Unlicensed Mobile Access, we think, is one of the technologies that will help us continue to deliver on that promise. But Kineto Wireless, one of the companies developing software to enable the service, said a commercial service is expected to launch this month in at least one major city. T-mobile has been testing the service for about a month in the Pacific Northwest, according to....continued....news.zdnet.com
