Google Enters Cell Phone Market with Software
PlanetaCelular tecnologia e mobilidade
Tweet
Google today unveiled a new software platform and a broad alliance of mobile handset makers and communications companies in a bid to accelerate the slow development of the mobile internet.
Engineers have been working on the software for three years, dating back to a Silicon Valley startup called Android Inc. that Google acquired in 2005. The mobile software still bears the Android name in acknowledgment of its heritage.
Android is designed to make it easier for developers to create mobile applications that run on many different handsets. At the moment, mobile technology is fragmented, relying on a several different operating systems and development environments. That has reduced the potential market for developers creating games, entertainment or other services for any one handset.
The alliance members come from the telecom and wireless software industries. Many of them are second-tier players that Google hopes will use the phone technology to build devices that can challenge the likes of Nokia, Apple and Verizon Wireless.
The list of wireless carriers that have agreed to provide service for the Google-powered phone in the United States include Sprint Nextel and Deutsche Telekom's T-Mobile in the United States. China Mobile, Telefonica in Spain and Telecom Italia are among the carriers that have signed on to provide service outside the United States.
They are among a Google-led group of 34 companies that have formed the Open Handset Alliance. Other key players include major chip makers like Intel, Qualcomm, Texas Instruments, Broadcom and Nvidia.
What Google gets in return is more real estate for selling ads. Ninety-nine percent of Google's revenues come from ads, either the ones it puts next to free Internet-based services like search and email, or through syndication on third-party Web pages. The bigger the Internet gets, Google executives figure, the more pages there are for ads and the more people will need search (with more ads) to find anything.

Samsung, Bang & Olufsen Serenata Music Phone Showcased
PlanetaCelular tecnologia e mobilidade
Tweet
Samsung Electronics and audio product maker Bang & Olufsen today unveiled their latest joint music-mobile phone, Serenata, which holds 4 GB of songs and has a number of other music features similar to the iPhone.
Serenata is a music mobile phone focusing on sound quality. Bang & Olufsen's expertise in concept development, user interface experience, acoustic sound capabilities and design skills together with Samsung's leadership in mobile phone technology, engineering and quality have realized a new way of combining unique music and mobile experiences for consumers.
"We have high expectations to Serenata, as it is a result of our joint vision to constantly push the boundaries, and bring unique and exciting products to our customers," states Torben Ballegaard Sorensen, CEO of Bang & Olufsen.
Serenata represents an innovative approach to a personal music player. Two companies' technology and design bring the experience of digital music to quite another level for music fans on the move.
Serenata features a built-in stereo speaker system which delivers outstanding sound quality. Equipped with a built-in hi-fi speaker and outstanding bass system, the phone delivers high quality sound without any distortion. With this state-of-art technology, mobile phone users can enjoy various kinds of music from pop and rock to jazz and classic in the same way they would through their hi-fi system at home. Users can listen to the opera in a music quality as if they were there themselves through the integrated loudspeaker system or through the dedicated stereo EarSet 3.
Combining only top-performing speaker components with ingenious acoustic principles and Bang & Olufsen-patented ICEpower amplification, the Serenata gets the world's best acoustic performance. The focus has been to provide authentic music performance, with emphasis on playback of "uncompressed" music. Besides handling lossless, Serenata also handles playback in various formats, including MP3, WMA, and AAC.
As a dedicated music phone, Serenata brings special ringtones for the users who want to have unique and sophisticated sounds designed by Bang & Olufsen. The sound achieved from a triangle, wind chimes, various types of glass and different types of woods will offer beautiful sounds to match any situation.
Serenata is a pocket-sized music mobile phone with an organic rounded design. "I often take long walks by the sea where I live," explains Bang & Olufsen designer David Lewis, "and the shape of the nicely rounded stones that are washed to shore has always fascinated me. These stones have been carefully shaped and rounded by rolling in the water for millions of years, and they are so wonderful to hold in your hand. This was what I was looking for."
The contrast between the cool aluminium and the warm soft touch lacquer leaves an impression of elegance, slimness and craftsmanship. The unique music phone's sound quality and elegant design does not compromise the ease of use. The click wheel navigation gives users hassle-free control of music functions.
"The basic idea is simplicity and one-hand operation. There are very few actual keys. We use the wheel for all primary operation in the context sensitive menus, like dialling, writing and accessing the music lists. For secondary operation, the wheel is supported by on-screen operation based on sensi-touch technology," explains Bang & Olufsen Chief designer David Lewis.
To assist the user throughout, the display changes color depending on whether it is in Phone mode (blue) or Music mode (red). Furthermore, the large 2.4-inch color LCD display developed by Samsung allows Serenata to show album covers in an excellent resolution and facilitates on-screen navigation. Also, the innovative mobile phone features sensi-touch to enhance the usability.
"Besides the color-coding and intuitive user interface, we try to help the first-time user with a 4-minute simulation tutorial, which is played in the display, explaining some of the most frequently-used functionality," Bang & Olufsen Business Manager Brian Laursen explains.
To enhance the usability, Bang & Olufsen has developed BeoPlayer, a simple software that can access and organise all music files on the PC and conveniently transfer them to Serenata. Also through the Samsung PC studio, the users can synchronise the contacts, calendar and to-do list from their computer onto Serenata via Microsoft outlook.
With Samsung's leadership in mobile phone technology, Serenata represents a unique harmonization of music and mobile phone features.
To offer enhanced multimedia functions, Samsung brings High Speed Downlink Packet Access (HSDPA) connectivity to Serenata. With 3.5G connectivity, users can enjoy full multimedia features including music and video, e-mail, MMS and instant purchase and download of music tracks. Also the phone features a 4 GB solid-state memory for storing digital music and data.
Featuring hi-fi speakers to deliver high quality sound reproduction and telephony, Serenata also provides a portable conference call feature, enabling multiple users to have a phone call a few feet away from the mobile phone.
Playback of music without disturbance from incoming calls or messages is made possible via the PureMusic function. Serenata still receives calls in the answering device or messages in the inbox, but doesn't disturb users while listening to the music.

MySpace Comes to T-Mobile Sidekick
PlanetaCelular tecnologia e mobilidade
T-Mobile Sidekick 3 / T-Mobile Sidekick iD
Tweet
T-Mobile and MySpace today announced MySpace Mobile for the T-Mobile Sidekick, designed to deliver the MySpace experience to Sidekick users.
MySpace Mobile is made possible on the T-Mobile Sidekick through two components. The first component is the client software, being made available for download in a staged rollout to the T-Mobile Sidekick user base throughout the next several weeks. The second component is the service that powers the application. Danger has created a private interconnection to MySpace, whereby each user can access all of his or her account data and interact with friends in real-time. Additional MySpace Mobile features include:
Customized User Interface (UI)
The new service has pertinent information including new messages, friend requests and comments located in one easy-to-navigate home screen. To use other aspects of the service, users simply navigate through the four main sections of the application: Home, MyMail, Blog and Search. The Sidekick's directional pad allows users to jump easily from each activity without waiting for a page to load.
Real-time Updates
MySpace Mobile users can stay signed in to MySpace even when they are on the go with their T-Mobile Sidekick. Real-time features include:
- Profile editing, which allows users to edit their MySpace profile directly from the MySpace application, quickly and easily, wherever they are. Profile updates are immediately reflected on the MySpace Web site.
- Optimized photo management, which empowers users to - with the click of a button - upload photos with captions from their T-Mobile Sidekick photo galleries, directly to MySpace.
- Full-featured MySpace messaging, including push content and notifications powered by the Danger service. The service automatically pushes content, such as new friend requests or new messages, to the end user, meaning that users are notified of new MySpace activity even when they are using other T-Mobile Sidekick applications. This changes the interaction paradigm from request/ response (as it is via the browser today) to real-time, push messaging.
- The application will provide "Online Now" status for a user's friends who are online, further advancing the "always-on" model.
- Users can read, reply to or post comments to the profiles and photos of friends, as well as read and reply to comments on their own profiles.
This week, T-Mobile will begin a multi-week rollout of the new application to T-Mobile Sidekick users. T-Mobile customers can access and subscribe to the service through the Download Catalog. The new service will be available to all Sidekick 3 and Sidekick iD users by the end of October.

T-Mobile Wins German Apple iPhone Deal
PlanetaCelular tecnologia e mobilidade
Tweet
Deutsche Telekom's mobile phone division, T-Mobile, will sell Apple's iPhone in Germany for 399 euros ($558) each, the companies said today. Making its debut in Germany on November 9, the iPhone combines three devices into one - a mobile phone, a widescreen iPod, and a mobile Internet device - all based on Apple's multi-touch interface and software that allows users to control the iPhone with just a tap, flick or pinch of their fingers.
"We're thrilled to be partnering with T-Mobile to bring the iPhone to Germany," said Steve Jobs, Apple's CEO. "Customer response to iPhone in the US has been incredible, and we can't wait to introduce T-Mobile customers to the most revolutionary mobile device on the planet."
"We are convinced that we can get our customers excited about experiencing the mobile internet with the iPhone," said Hamid Akhavan, CEO, T-Mobile International. "I am proud that Apple and T-Mobile have become partners. The best mobile device currently on the market will soon be operating on the best network in the country."
iPhone users in Germany will have access to Apple's latest music offerings on iPhone including the recently launched iTunes Wi-Fi Music Store. The iTunes Wi-Fi Music Store offers customers the ability to browse, search, preview, purchase and download songs and albums from iTunes over the built-in Wi-Fi on their iPhone. No computer is required and when the customer connects their iPhone back with the PC or Mac, their music automatically syncs back into their iTunes library.
The T-Mobile network will also support iPhone's unique Visual Voicemail feature, which enables users to immediately randomly access those messages that interest them most.
By the end of 2007, T-Mobile will be the only network operator in Germany to offer EDGE throughout its entire GSM network. EDGE accelerates the mobile data transfer rate to over 220 Kilobits per second, which makes it almost four times as fast as ISDN in fixed-line networks. With EDGE, the German market leader offers its customers 100 percent broadband. With 20,000 HotSpots worldwide, T-Mobile is the biggest Wi-Fi provider in the world. Of those HotSpots, 8,600 are in Germany, where HotSpot users can achieve download speeds of up to 11 megabytes per second.

Frequent Cell Phone Use May Slow Brain Function
PlanetaCelular tecnologia e mobilidade
Tweet
A study says frequent cell phone users demonstrated slowed brain function but it was still considered within normal brain functioning.
Earlier studies have mostly investigated the acute effects of cell phone use on brain function. However, this study employed an epidemiological approach to investigate the long-term effects of cell phone use on brain function. In this study data was used from 300 people of which 100 were 'frequent cell phone users', 100 'non-cell phone users' and an 'intermediate group' of 100 people.
Differences in brain activity (measured using QEEG or quantative EEG), Neuropsychological functions such as attention, memory and executive function and personality traits were assessed. The results show that frequent cell phone users score higher on extraversion. Furthermore, frequent cell phone users showed improved focused attention. This was explained by a learning effect due to making more phone calls in busy environments, whereby people learn to focus better on the phone call and filter out irrelevant environmental information. However, the brain activity from frequent cell phone users shows more slow activity (increased Delta and Theta) and a slowing of the Alpha Peak Frequency. These effects could not be explained by the differences in personality and focused attention. "In Alzheimer's dementia you also find a severely slowing of brain activity.
However, the slowing found in this study, with cell phone users, can still be considered within 'normal' limits" according to Martijn Arns, the main investigator. "The frequent cell phone user group used their cell phone - at the time of data collection - only 2.4 years on average which can currently be considered as a short time. Therefore, it is to be expected that the observed effects in this study can be more severe with prolonged cell phone use" according to Martijn Arns.
Future studies should point out whether this effect can be replicated in larger groups, with prolonged cell phone use and whether this slowed brain activity is to be considered as an adverse health effect or not.
This study was carried out by researchers from Brainclinics Diagnostics and the Radboud University department of Biological Psychology both from Nijmegen (the Netherlands), the Institute of Psychiatry (London) and the Brain Resource Company Ltd. (Sydney).

Laser Technology Leads to Better Cell Phones Displays
PlanetaCelular tecnologia e mobilidade
Tweet
UCLA chemists working at the nanoscale have developed technology which could lead to brighter cell phone displays with less power consumption. The new, inexpensive means forces luminescent polymers to give off polarized light and confines it to produce polymer-based lasers.
The researchers, Sarah Tolbert and Benjamin J. Schwartz, have succeeded in taking semiconducting polymers - plastics that consist of long chains of atoms that work as semiconductors - and stretching them out in a silica (glass) host matrix so that they have new optical properties.
"If you have polymer chains that can wiggle like spaghetti, it's hard to make them all point in the same direction," Tolbert said. "What we do is take tiny, nanometer-sized holes in a piece of glass and force the polymer chains into the holes. The holes are so small that the spaghetti chains have no space to coil up. They have to lie straight, and all the chains end up pointing in the same direction."
Because the chains point in the same direction, they absorb polarized light and give off polarized light. Lining up the polymer chains also provides advantages for laser technology, because all the chains can participate in the lasing process, and they can make the light polarized without the need for any external optical elements, Tolbert said.
"Our new materials exploit the fact that the polymer chains are all lined up to make them into lasers that function very differently from lasers made out of random polymers," Schwartz said.
The manner in which the polymer chains incorporate into the porous glass of the silica matrix helps to confine the light in the material, enhancing the lasing process by producing what is known as a "graded-index waveguide." In most lasers, confining the light is typically done with external mirrors.
"Our materials don't need mirrors to function as lasers, because the material that's lasing is also serving to confine the light," Schwartz said.
In combination, the alignment of the polymer chains and the confinement of the light make it 20 times easier for the new materials to lase than if a randomly oriented polymer sample were used. And because polymers can be dissolved easily in solvents, they are inexpensive to process. The glass host matrix with the aligned nanoscale pores is also inexpensive to produce.
"Usually polarized and cheap don't go together," Tolbert said.
The research opens the possibility of additional applications for the new materials as a brighter polarized source for displays in products with LED-type displays, including cell phones.
"If you take an inexpensive light source with which you could excite the aligned polymer chains and get the chains to reemit, you potentially have a more efficient way to generate polarized light." Tolbert said. "This would allow displays to be brighter with less power consumption, and you could get longer battery life."

Nokia Supports Common Flash Storage Technology
PlanetaCelular tecnologia e mobilidade
Tweet
Nokia said it and several other industry heavyweights support the creation of a common flash storage technology that removes the need for adaptors to accommodate different removable memory card sizes.
Nokia said Micron, Samsung, Sony Ericsson, Spansion, STMicroelectronics, and Texas Instruments all support the new specification, dubbed Universal Flash Storage, or UFS.
The new specification reflects the industry's need for a universal memory solution. Widespread demand for higher densities and higher performance, plus the popularity of multimedia content, is accelerating the need for advanced memory solutions in removable card formats. UFS will support very low access times required for memories, as well as high-speed access to large multimedia files, while reducing power-consumption. The target performance level is expected to be a significant advancement beyond that of the varied flash cards popular today. Today, users experience a three-minute access time for a 90-minute (4 Gigabyte) high-definition movie; with the new standard, this would be reduced to a few seconds.
UFS is expected to give consumers the convenience of a unified removable memory card that can be shared among various mobile, portable and other consumer electronic devices without the need for any adaptors. The UFS standard is expected to be finalized in 2009.
