3G, 4G, WiMAX, 802.20, ABI - do we need them all ?

Last week, AT&T Wireless debuted UMTS services in Detroit, Phoenix, San Francisco and Seattle. Based on technologies shared with Japan's NTT DoCoMo, these are, says the company, the first commercially available 3G UMTS services available in the United States.

That's good news, but is it the whole story? The wireless industry is basing its market strategy on the assumption of an evolution to 4G services, possibly based on orthogonal frequency-division multiplexing (OFDM). NTT DoCoMo expects to roll out its first 4G services in Japan within three years.

Smooth high-speed video and other forms of high-speed data are among the central benefits 4G proponents are touting, and are important reasons for its development. Yet, there are 3G networks delivering them already. WiMAX promises to do the same. So is the need for 4G inevitable?

According to ABI Research's vice president of research, Edward Rerisi, it's all about subscriber numbers and demand. Compared to present-day 3G, fourth generation technologies, he says, will be able to provide many more customers with these rich-media experiences at the same time.

It's all a question of the level of demand for data-based services, and there will be a wide variety to choose from. Some users may want video; some may transfer multi-megapixel images and still others might find location-based services, enterprise applications, or any of the other sophisticated data-based offerings more compelling.

"In any case," adds Rerisi, "when when consumer demand accelerates, the true value of '4G' will be revealed."

ABI Research's report, "Broadband Wireless - Last Mile Solutions" examines the technical features of these technologies and the complex dynamics of this market.

Founded in 1990 and headquartered in New York, ABI Research maintains global operations that support annual research programs, quarterly intelligence services and market reports in wireless, automotive, semiconductors, broadband, and energy.

One of the most I've been waiting for

This article on silicon.com remember me what i've been present on my post-graduate class a few years ago. I got my interesting assignment to present a future technology f telecommunications. Here are the article :



Holograms on handsets by 2010

Forget 3G, mobiles go 3D

Holographic mobile handsets capable of projecting, capturing and sending 3D images have been developed by an Indian tech company.

By 2010 the devices will routinely beam 3D films, games and virtual goods into our laps according to Indian technology giant Infosys, which has patented the handset.
The portable machines will capture and send 3D snapshots of the surrounding world, helping accident investigators, teachers and doctors work remotely by instantly relaying realistic depictions of car damage, injuries, medical scans or educational aids.

The powerful onboard processor on the Infosys machine would build a series of 2D shots taken, for example, from a digital camera, into 3D holograms using algorithms called 'Fourier' transformations to calculate the extra third dimension.

The patent, granted by the US Patent and Trademark Office, says this allows complex 3D holographic images to be squeezed through the narrow pipes of existing communications networks, by sending only the unprocessed data to be translated into the 3D hologram at the other end.

Infosys' device will be able to both send and receive these 3D images, displaying them using a projector with a laser source and micro holographic optical elements lenses.

The global 3D screen market is forecast by industry to grow to 8.1 million units by 2010.

A spokeswoman for Infosys said: "Holographic handsets have the capability of enriching the user experience, with an actual 3D experience and higher quality images. This gives users a more realistic experience in areas like gaming, medicine, movies etc."

She said the technology would enable 3D images to be displayed without losing resolution, something that is not possible using current 3D technology, such as stereoscopic displays.

This remarkable technology as I remember firstable introduced by NTT DoCoMo Japan through their film of Vision 2010, and it said that they plan to deploy it on 2012. We can see their newest video of Vision 201X now.It was an interesting promo movie that explore my knowledge much better. The requirement of 500MBps bandwidth to held the communication become a challenging part. Who would be the first?
