The first Mobile IP PDA for seamless access demonstrated by a member of the EURESCOM project team
+++ EURESCOM for the first time demonstrates seamless access with a PDA. +++
Premiere at the EURESCOM workshop `Wireless Access` in Heidelberg on 12 March: The EURESCOM project on `Bluetooth Access` presented the first PDA, which can seamlessly connect to different access networks, like LAN, Bluetooth, Wireless LAN, and GPRS.
In co-operation with the software company Birdstep from Norway and access point supplier Patria Ailon from Finland, the European project team implemented Mobile IP on a PDA with the operating system Pocket PC 2002. The Mobile IP PDA has a built-in priority mechanism for selecting automatically the best available network access.
Seamless handover between networks is especially convenient for downloading large volumes of data, explains Josef Noll: "Let us assume, I am on the move with my PDA. Via GPRS my e-mails will always be updated, but downloading large attachments, like video files, might take too long with GPRS. But as soon as I get close to a Bluetooth network, which has much more capacity, the download can immediately begin, without re-configuring the PDA."
Mr Noll expects PDAs with seamless access, based on Mobile IP, to be available for corporate customers by the end of 2002 and for private users by the end 2003. He is convinced that after EURESCOM`s first successful demonstration of seamless access, others in the telecommunications domain will follow in developing Mobile IP-based devices.

Nanooptical traps are a promising building block for quantum technologies. Austrian and German scientists have now removed an important obstacle to their practical use. They were able to show that a special form of mechanical vibration heats trapped particles in a very short time and knocks them out of the trap.
By controlling individual atoms, quantum properties can be investigated and made usable for technological applications. For about ten years, physicists have...
An international team of scientists, including three researchers from New Jersey Institute of Technology (NJIT), has shed new light on one of the central mysteries of solar physics: how energy from the Sun is transferred to the star's upper atmosphere, heating it to 1 million degrees Fahrenheit and higher in some regions, temperatures that are vastly hotter than the Sun's surface.
With new images from NJIT's Big Bear Solar Observatory (BBSO), the researchers have revealed in groundbreaking, granular detail what appears to be a likely...

Carbon nanotubes (CNTs) are valuable for a wide variety of applications. Made of graphene sheets rolled into tubes 10,000 times smaller than a human hair, CNTs have an exceptional strength-to-mass ratio and excellent thermal and electrical properties. These features make them ideal for a range of applications, including supercapacitors, interconnects, adhesives, particle trapping and structural color.
New research reveals even more potential for CNTs: as a coating, they can both repel and hold water in place, a useful property for applications like printing,...
If you've ever tried to put several really strong, small cube magnets right next to each other on a magnetic board, you'll know that you just can't do it. What happens is that the magnets always arrange themselves in a column sticking out vertically from the magnetic board. Moreover, it's almost impossible to join several rows of these magnets together to form a flat surface. That's because magnets are dipolar. Equal poles repel each other, with the north pole of one magnet always attaching itself to the south pole of another and vice versa. This explains why they form a column with all the magnets aligned the same way.
Now, scientists at ETH Zurich have managed to create magnetic building blocks in the shape of cubes that - for the first time ever - can be joined together to...
