Article Abstract:
The volatility of the telecommunications market as evidenced by the many mergers in the past few years is due in part to the emergence of a new breed of telephony and in part to the rise of a world market. Some companies merged to increase their service areas, whereas some merged with companies that provided complimentary services to increase their market and allow them to provide new services. Cellular technology has gained worldwide acceptance, especially in countries that do not already have an embedded land line system in place. Voice over IP technology has received a great deal of attention for its ability to deliver voice and data over a single architecture. The new telecom giants are preparing to market the new technologies even as they are still being developed.

Optical networks brace for even heavier traffic
Article Abstract:
Backbone infrastructure owners are looking for ways to add capacity to their fiber-optic systems and the Internet is cited as a reason. Backbone traffic is increasing at a compound annual growth rate of more than 100 percent in Europe and the U.S., compared to a rate of only 6 to 10 percent in pre-Internet times. However, having sufficient backbone capacity does not address the problem of the 'last mile,' the connection between the service provider and the end user. An innovative approach being pioneered by Telebeam involves beaming optical waves through the air. A fiberless optical service would eliminate the need to install fiber but would only work if subcribers have line-of-sight access to a service provider's site.

Mighty mites: the fuel cell's first big market success may be alcohol-fed units small enough to power cellphones, laptops, and PDAs
Article Abstract:
Leroy Ohlsen, founder of Neah Power Systems Inc, Bothell, WA, envisions fuel cells as replacements for batteries in handheld devices such as cellphones, personal digital assistants (PDA) and laptop computers. Alcohol-fed fuel cells, aka direct methanol fule cells (DMFC), are seen as more practical than hydrogen cells for portable applications.
