As the volume of “traffic” on the Internet grows at an enormous rate – estimates are that it is doubling every year – scientists in several countries have begun working to measure this incremental growth and to devise methods for more efficient means for future networking.

One major project is EVERGROW, a European Union-funded program involving 25 universities in Europe, Israel and Egypt and selected high-tech communications companies. Scientific co-coordinators of the project are Prof. Scot

Lehigh engineering professor is testing the usefulness of multitier networks in remote areas that lack digital and cable-modem access

When the providers of Internet services look at a map of Susquehanna County in northeastern Pennsylvania, they see a hilly, lightly populated region that offers little financial incentive to install the wires necessary for digital or cable-modem access.
When Shalinee Kishore looks at Susquehanna County, she sees a chance for wireless technology to give ru

SkyPlex is a technological and commercial breakthrough in Satellite Telecommunications. Due for launch on 16 March from Baïkonour aboard Eutelsat’s W3A satellite, SkyPlex will deliver Internet and TV services.

Developed by the European Space Agency (ESA) with Alenia Spazio as prime contractor, SkyPlex is used by Content Providers, companies and Internet Service Providers. Today there are 12 SkyPlex units in orbit aboard the following Eutelsat satellites: Hotbird 4 (one unit), Eurobird 2 (3

Between June and August 2003, France Telecom tested a unique system for real-time, wireless and continuous transmission of medical data on patients transported by ambulance. The SAMU (emergency medical services) headquarters are constantly updated on changes in the condition of the patient being transported and on transport conditions during the transfer to the destination chosen.

This continuous data transmission is made possible using Orange’s GPRS network for mobile telecommunicatio

The digital watch you just bought interacting with your mobile phone? Now a new prototype allows wearable and portable devices communicate with each other via Bluetooth.

The successfully tested 2WEAR prototype is a wearable personal network that links together computing elements in an ad-hoc fashion using short-range radio. Certain elements are embedded into wearable objects, such as a wristwatch and small general-purpose computing and storage modules that can be attached to clothes or plac

Fast Internet connections are all the rage, mostly over DSL and cable modems. But a little-known competitor – a technology that promises speeds up to 200 megabits per second over existing electrical infrastructure – is jostling for a place in this lucrative market.

In January 2003, broadband services – used to transmit voice, data or video signals simultaneously – had either been requested or were already available in around 7 per cent of European Union households. The Yankee Group predicts
