New Electronics Promise Wireless at Warp Speed

Click For Summary

Discussion Overview

The discussion revolves around the potential of new wireless networking technologies to deliver high-definition video and large data files at unprecedented speeds, exploring the advancements needed in electronics, particularly in semiconductor materials and designs.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that conventional silicon-based semiconductors may be replaced by metal-insulator electronics, which can utilize cheaper substrates like glass or plastic, enhancing wireless capabilities.
  • Another participant highlights the advantages of using 60GHz frequencies for wireless networks, noting that these frequencies can be contained by walls, allowing for distinct networks in different rooms.
  • A later reply humorously comments on the necessity of line of sight for some wireless technologies, implying that the 60GHz feature is beneficial.
  • One participant proposes that graphene-based transistors could contribute to faster data transmission, contingent on achieving sufficient thinness for practical use, while also noting that receiving devices must match or exceed transmission speeds.

Areas of Agreement / Disagreement

Participants express various viewpoints on the technologies and materials that could enhance wireless data transmission, with no consensus reached on the best approach or the feasibility of the proposed solutions.

Contextual Notes

The discussion includes assumptions about the capabilities of new materials and technologies, as well as dependencies on the development of compatible receiving devices, which remain unresolved.

SF
Wireless networking technology will one day deliver high-definition video content and other large data files via the airwaves far faster than that information can be now be delivered over wired systems. But it will take major advances in the electronics that drive computer and radio-frequency systems to create such a high-powered wireless highway.
[..]
Conventional semiconductors are built using silicon-based substrates (the material upon which semiconductor devices are fabricated), but metal-insulator electronics can be made atop less pricey glass, metal or plastic substrates. Phiar's approach is to place two metal layers on either side of a double layer of insulation. When voltage is applied, electrons tunnel through the insulator layers with the help of a "quantum well" that forms between the two insulators.

I love the quote about using 60GHz for wireless. "Since higher frequencies are more easily contained by walls you can have a different 60GHz network in each room" - instead of "our new wireless requires line of sight to the transmitter"
 
Hey! It's a "feature" not a bug.:rolleyes:
 
maybe the graphine-based transistor will help with that. granted some one can get it thin enough to use by the time that gets going. I mean if info is being transmitted that fast, the comp/recieving device would need to as fast/faster to compensate for it.
