From Broadband to Ultra Wide Band (Mar 2002)
Ultra Wide Band (UWB) is a data transmission method which uses very short duration pulses over large transmission bandwidths. In English, that means a lot of information goes from point A to point B very rapidly by sending all of it in one big cluster. The emergence of Ultra Wide Band could have a revolutionary impact on data transmission and consumer electronics. The technology could be applied to set up wireless cable TV or computer networks at home, or to enable users to swap enormous amounts of data almost instantly.
Copper Battles Optical for the Cable Infrastructure Future (Aug 2001)
Gigabit Ethernet has kicked the dilemma between copper-based and optical cabling into high gear. Alternatively known as 1000Base-T, the new gigabit networks will up the ante on the performance of the cable infrastructure in many organizations. The rapid expansion of Gigabit Ethernet will force IT managers to confront this problem and make some tough decisions.
Enterprise Broadband Can Cut Costs (May 2001)
Internet emphasis has shifted from processing speed to bandwidth. The need for wider pipes grows with increases in traffic along with graphic and sound content. As an alternative to traditional T1 or ISDN lines, broadband access can reduce both costs and hassles.
Globalstar Expands Mobile Satellite Services (Sep 2000)
In February 2000, Globalstar USA launched its mobile satellite service in the United States, providing seamless voice service coast to coast with international roaming capabilities. A rollout of commercial Globalstar services began at the end of 1999, and it is anticipated that completion of the basic network rollout will be achieved by the first quarter of 2001, at which point Globalstar service will be available in over 120 countries served by 38 gateways.
DSL Can Payoff in Enterprise Applications
Digital subscriber line (DSL) is the phone company's answer to low cost, wide bandwidth communications channels. Challenging DSL are the cable companies, which offer cable modems. From a business standpoint, the matter certainly tilts in favor of DSL, although few companies have yet taken the plunge. This analysis looks at the issues that confront an IT manager considering DSL installations and what tradeoffs need to be addressed.
