Telecommunications
Article Abstract:
Telecommunications may be the final indicator of the success of the European unification plan. A technical infrastructure that permits a variety of networks to be seamlessly stitched together is a basic requirement for a single market. A 192-page report from the European Community's Commission recommends a Western Europe-wide telecommunications infrastructure founded on the ISDN and other digital communication links. The Commission's plan calls for the national Post, Telegraph, and Telephone administrations, which now regulate information flow, to have much less power. The market for terminal equipment would be open to everyone. Progress on establishing a telecommunications infrastructure varies from country to country. The variable quality of network services in different countries is another obstacle. But a trans-European ISDN system is beginning to materialize and work on specific technologies, standards, and regulations is underway. Work on upgrading the capacity for existing applications is also underway.

Telephone wiring: a conduit for networking standards
Article Abstract:
Emerging IEEE 802.3 standards for local-area networks (LANs) that run on conventional twisted-pair telephone wire are making it less expensive and easier to implement data-voice LANs. Use of twisted-pair simplifies installation and reconfiguration of LANs, and their cost is much lower than coaxial systems. The 802.3 working group has already approved an AT & T StarLAN-based 1M-bit-sec standard, IBASE5, which is a star topology network that supports computers up to 250 meters from the hub. An 802.3 task force is also developing 10BASE-T, a 10M-bit-sec LAN implementation that will support distances up to 100 meters from the hub, have a bit error rate of one in 100 million, and be compatible with the existing 802.3 standard. Such systems will probably dominate the LAN market through the early 1990s.

Manufacturing hurdles challenge large-LCD developers
Article Abstract:
Viable large flat-panel liquid crystal displays (LCDs), particularly color and high-definition television (HDTV)-sized ones, require substantial technological advances to compete with cathode-ray tube (CRT) displays. Active-matrix LCDs are expected to replace supertwist LCDs as the choice for large displays, but significant improvements in high-volume semiconductor production and large-surface amorphous-silicon manufacturing techniques are necessary to achieve market-appropriate economies of scale. Japanese electronics companies, especially those in the Ministry of International Trade and Industry-supported 'Giant Electronics Project' joint venture, are actively pursuing HDTV-sized active-matrix LCD panel technology. Large-panel LCD technology developments in the US and Japan are described.
