The Future of Wide Area Networks

  • Lakshman T.
  • Sparks K.
  • Thottan M.

We are entering a new technological era where everything will be digitized and there will be an unprecedented demand to connect this massive new set of digital goods to create new value in terms of automation of lives and systems. The network will require the ability to deliver information and entertainment content at massive scale but with an economic outlay that is not vastly different than today. This requirement comes at a time when we have reached the physical limits of todays network performance and so a top to bottom restructuring of networks is required, with a wholesale shift to highly distributed, highly intelligent optimized networking. Todays self contained standalone networking constructs whether it be an operator, a network, a network layer, or a network element will be dis-aggregated and then realigned and reintegrated at different levels using a set of new software platforms and interfaces. This will require a new automated control paradigm that will make networks truly programmable and the essential building blocks of a new digital connected reality.

© 1963-2012 IEEE. This article presents a packaged SiGe BiCMOS reflectometer for 0.01-26-GHz two-port vector network analyzers (VNAs). The reflectometer chip is composed of a resistive bridge coupler and two wideband heterodyne receivers for coherent magnitude and phase detection. In addition, a high-linearity receiver channel is designed to accommodate 20 ...

Protecting photonic quantum states using topology

  • Blanco-Redondo A.

The use of topology to protect quantum information is well-known to the condensed-matter community and, indeed, topological quantum computing is a bursting field of research and one of the competing avenues to demonstrate that quantum computers can complete certain problems that classical computers cannot. In photonics, however, we are only ...

Digital networks at the nexus of productivity growth

  • Kamat S.
  • Prakash S.
  • Saniee I.
  • Weldon M.

This paper takes a fresh look at the debate over the relationship between digital technology and productivity. The argument of economic historian Robert J. Gordon is that digital technology will not lead to increases in productivity such as we saw in the last century, based on his analysis of the ...
