The Power of Wireless

August 25th, 2008

Say goodbye to the tangle of cables and the wall socket and hello to powering up your electronic gizmos wirelessly.

This picture of a world without wires is one long dreamed of and came a step closer following significant progress made by Intel.

It said it has increased the efficiency of a technique for wirelessly powering consumer gadgets and computers.

“The notion of disappearing energy sources is a powerful one,” Justin Rattner, Intel technology boss, told the BBC.

“Wouldn’t it be fantastic if we didn’t think about where the power was coming from and the power was everywhere?” Justin Rattner, Intel technology boss stated. “No cords, no batteries anymore.”

Mr Rattner envisaged a scenario where a laptop’s battery could be recharged when the machine gets within several feet of a transmit resonator which could be embedded in tables, work surfaces, picture frames and even behind walls.

Intel’s technology relies on an idea called magnetic induction. It is a principle similar to the way a trained singer can shatter a glass using their voice; the glass absorbs acoustic energy at its natural frequency.

At the wall socket, power is put into magnetic fields at a transmitting resonator – basically an antenna. The receiving resonator is tuned to efficiently absorb energy from the magnetic field, whereas nearby objects do not.

“This is a potentially world changing event,” said analyst Rob Enderle of Enderle Group.

“This is the closest we’ve had to something being commercially available in this class.”

Mr Rattner admitted the technology is at least five years away, if not more, of becoming a reality.

 

Intel Centrino 2 Platform Launches On Monday, July 14th

July 12th, 2008

As notebook shipments have begun to significantly outpace the sales of desktop computers, each new notebook platform launched by Intel becomes more important to the company. This Monday July 14 marks the launch of Intel’s Centrino 2 platform, previously known by the code-name Montevina. The launch comes weeks after Intel had planned due to a problem with Intel’s own integrated graphics for the platform.

In fact, the Centrino 2 notebooks running Intel’s own integrated graphics will not be available on Monday. Only Centrino 2 systems running discrete graphics from NVIDIA or ATI will be available on Monday.

According to eWeek, the Centrino 2 platform is aimed at enterprise users, but it will find its way into consumer focused notebooks as well. The Centrino 2 platform will be the first mobile platform to take advantage of Intel’s new 45nm Penryn CPUs and the CPUs will run from 2.4GHz to 2.8GHz.

Also supported by the Centrino 2 platform is DDR3 RAM along with 802.11n and WiMAX. The move from the 65nm CPUs used in previous mobile platforms to 45nm parts in the Centrino 2 platform should lead to increased battery life and lower heat output — both very important to notebook users. The first 45-nm processors in the Centrino 2 platform will be dual-core parts, but quad-core CPUs will be available for the platform later.

Intel revealed in a blog post that the Centrino 2 platform processors will run at 25 watts whereas the older processors ran at 35 watts.
