The issue with 4G backhaul is a simple one: T1-line backhaul, which many carriers -- particularly in the U.S. -- use extensively, cannot cope with base stations that pump out data at hundreds of megabits a second to provide a few megabits-a-second data downloads to each individual user. Yet faster data downloads are supposed to be what sells so-called 4G services -- be they WiMax or Long-Term Evolution -- to consumers. Carriers, meanwhile, want 4G to further bump up data revenues, which are supposed to supplant declining voice revenue over time.
Using GPS data to estimate prevailing speeds and travel times, researchers have been able to obtain a picture of real-time traffic conditions. Current traffic monitoring systems mostly rely upon pavement-embedded sensors, roadside radar or cameras. The high cost of installing and maintaining such systems has restricted their coverage to only limited stretches of highway.
GPS systems, on the other hand, are becoming ubiquitous and are relatively cheap. The technology can pinpoint a car's location to within just a few feet and calculate its speed to within three miles per hour. Enlisting GPS-equipped mobile phones into traffic monitoring systems could help provide information on everything from multiple side-street routes in urban areas to hazardous driving conditions or accidents on vast stretches of rural roads, the researchers say.
"Even though the phones are capable of sending their position and speed every three seconds, an efficient traffic monitoring system should not need to transfer such a large amount of data, which would require enormous bandwidth," says Alexandre Bayen, a University of California, Berkeley, assistant professor of systems engineering and civil and environmental engineering. "Our challenge is to find the optimum subset of this data for effective traffic monitoring," Bayen observes. "The quantity and quality of data provided by GPS-equipped cell phones present an unprecedented enhancement to mobility tracking technology and traffic flow reconstruction mechanisms."
Yet such a system also raises questions about phone users' privacy. That's why the researchers, with the help of Rutgers University's Winlab, have built privacy protection into the system. "Mobile device users control the service--if an individual does not want his or her device to transmit position data, he or she can turn off the GPS feed," says Quinn Jacobson, a researcher with the Nokia Research Center. The system's data is immediately disassociated from individual phones and is combined with the general stream of traffic data. "Only anonymous aggregated data is ever created, transported or stored in this 'privacy-by-design' system," Jacobson notes. All data is further protected by encryption.
A commercial launch date hasn't yet been announced for the system. But when it does become available, its benefits could be substantial. In the U.S. alone, traffic congestion leads to 4.2 billion hours in extra travel time and an extra 2.9 billion gallons of fuel burned, for a total cost of $78 billion, according to a 2007 report from the Texas Transportation Institute. With the number of vehicles on the road increasing rapidly worldwide, a cost-effective method of travel planning could help drivers make smarter decisions about which routes to take.

The software-service combo enables users to see the bandwidth usage of applications in real time. The tool also gives bandwidth utilization precedence to time-sensitive applications, including VoIP and video calls. Lower-priority applications, such as file transfers, run in background.
A Propel PBM subscription provides updated traffic shaping policies, protecting high-priority network applications, such as Skype, against current and new software applications. Propel PBM also includes a network traffic monitor that displays bandwidth utilization in real-time, enabling users to monitor their bandwidth usage, as well as to detect potential malware.
For example, a Skype call taken during a file upload can result in outgoing voice traffic suffering significant time delays or blockages as the two tasks compete for outgoing network bandwidth. The Skype traffic is higher priority because interfering with its packets can degrade the call quality. In contrast, the file upload is lower priority, since the file transfer will not break if preference is given to the Skype traffic. While an individual can attempt to protect high-priority networking applications, such as Skype, from low-priority traffic by turning them off manually, this is often inconvenient and time wasting.
A typical PC has dozens of programs that access the network. Propel PBM aims to prioritize all of this traffic automatically so that time-sensitive packets get higher priority than other traffic. The company states that Propel PBM's automatic behavior is based on policy definitions that are updated automatically, much in the way a virus protection program periodically downloads new virus definitions.
Propel PBM is targeted at the rapidly growing market of individuals who use network-intensive, time-sensitive applications, says David Murray, president and CEO of Propel, which is based in San Jose, Calif. "We've developed an easy-to-use, powerful application for helping individual PC users get the most from their network connection," he notes. "By using Propel PBM, PC users for the first time can be assured their high-priority, time-sensitive applications will run simultaneously with low-priority applications and maintain optimal performance in any given network condition."
Propel is privately funded and claims to be profitable. The company has raised three rounds of financing since its 1999 founding by a team led by Murray and Steve Kirsch, the company's chairman.
The internet, Web 1.0, is so incredibly powerful that even now, almost 20 years later, we have only begun to explore its potential. Web 2.0, with its YouTube, Facebook, Flickr and blogs galore is even younger and shows even more potential.
Now, thanks to the work of the WIP project, we may be on the brink of a new internet, a new world wide web. One where users can spontaneously create their own networks, in minutes, and with any kind of data device – mobile or fixed, handheld or deskbound. It means completely reinventing the internet, retooling its underlying technology, creating new operating principles and defining wholly new communications protocols so that it all works with any technology.
“When the internet first emerged, it assumed devices would be fixed in place and linked by wires,” remarks Marcelo Dias de Amorim, a researcher with the WIP project. “But that’s no longer true. A large number of devices are mobile and equipped with wireless communication capabilities.”
Many of the fundamental assumptions of the original internet have been superseded and many other pillars of the web are simply ad hoc (even bootstrap) solutions to discrete problems. It all appears rather accidental.
WIP wants to change all that, reinventing the internet and its underlying methods in what they cheerfully describe as disruptive technology. It is revolutionary, radical, but is it realistic?
