GANDALF Conjures Up Faster, Seamless Internet Technique
As the white wizard of Middle Earth in Lord of
the Rings, Gandalf had some astounding abilities. As his modern namesake, the
GANDALF project is set to cast a spell over the Internet world by offering
unprecedented data transfer rates seamlessly over both fixed-line and
wireless.
GANDALF has developed a groundbreaking technique to increase data rates by a thousand-fold compared to existing DSL and a hundred-fold compared to WiFi. The technology also allows data to flow seamlessly over both wireless and fixed-line communications, making the project the only initiative in the world to progress so far in both areas.
“Why not use the same technology for both fixed-line and wireless? That was the fundamental question that drove the project,” explains GANDALF coordinator Javier Martí in Spain. “We also saw the need to address the additional challenge of obtaining high rates of data transfer – exceeding 1 gigabit per second – over both cable and radio.”
“The major advantage for operators is that the cost of implementing GANDALF is minimal,” Martí says. “We estimate that it would not cost more than say 50,000 or 60,000 euros to implement it across an entire network, which is peanuts for operators.”
Most significantly perhaps, the system would give operators access to more clients without having to undergo costly public works projects to lay new fibre optic cable. Existing cable could be used to relay data to the closest access node to clients’ homes before being converted into a wireless signal.

In areas where both fixed-line and wireless accessibility exists, the GANDALF system offers additional advantages. “The duality of the communications channels increases reliability,” the coordinator notes. “For businesses or public administrations this is particularly important. Banks and other companies carry out a process called disk mirroring, for example, where they copy the databases from all their branches. Lost connectivity during mirroring can cause major problems but with dual connectivity the reliability is greatly increased.”
With the GANDALF technique, data transmissions switch seamlessly between fixed-line and wireless. “It is completely transparent to users,” Martí notes.
Similarly, the system can also be used to connect two fixed-line local area networks by radio without the need for new fixed infrastructure, something that the project partners are currently testing at the campus of the Technical University of Valencia. The same site will also be used for other field trials before the project ends in December.
In-lab tests have so far achieved a data transfer rate over both fixed-line and wireless of 1.25 Gb/s and the project partners are currently studying other capabilities of the system.

“The technology is here and it works, the only thing remaining is standardisation, depending on how well that goes I imagine a product will be on the market within a year from now,” Martí says. “So in the coming years you can expect, with confidence, that many companies will start using this technology and many people will be receiving data over it in their homes, probably in Spain through [Spanish cable operator] ONO at first and then across the rest of the world.”
Except the USA.
Update: This technology is beyond my ken. Geeks who wish to investigate further can go here.
