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.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...
Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
