Wireless Myths, Realities and Futures..

چکیده
The Myth [1]: Sixty years of research following Shannon’s pioneering paper has led to telecommunications solutions operating arbitrarily close to the channel capacity ’flawless tele-presence’ with zero error is available to anyone, anywhere, anytime across the globe... The Reality [1]: Once we leave home or the office, even top of the range iPhones and tablet-computers fail to maintain ’flawless tele-presence’ quality. They also fail to approach the theoretical performance predictions... The 1000-fold throughput increase of the best thirdgeneration (3G) phones over second-generation (2G) GSM phones and the 1000-fold increased tele-traffic predictions of the next decade require substantial further bandwidth expansion towards ever increasing carrier frequencies, expanding beyond the radio frequency (RF) band to optical frequencies, where substantial bandwidths are available. The Future [1]: However, at the time of writing opticaland quantum-domain wireless communications is less well developed than RF wireless. It is also widely recognized that the path-loss of RF wireless systems monotonically increases with the carrier frequency and this additional challenge has to be tackled by appropriate counter-measures in future research. Hence we set out to seek promising techniques of tackling the above-mentioned challenges and for resolving the conflicting design constraints imposed on the flawless tele-presence systems of the future.

Augmentative Communication and Early Intervention Myths and Realities
The use of augmentative and alternative communication (AAC) services and supports with infants and young children has been limited, owing to a number of myths about the appropriateness of AAC use with this population. This article will provide an overview of some of the myths that have hampered the inclusion of AAC into early intervention service delivery and refutes them. It will then examine ...

متن کاملChallenges and Benefits in an Open Data Initiative – Local Government Case Study of Myths and Realities
This paper investigates the myths and realities of open data at local government (a focused municipality) level. There are many expectations related to open government data (OGD) covering e.g. public transportation, car parks, public committee minutes and air quality measurements and the effects of more open public agencies and commercial possibilities, together with citizen benefits. Expectati...
متن کاملManaged care mythology: supply-side dreams die hard.
As managed care gains increasing influence over the American health financing system, economic pressures and emerging market realities have created a fertile climate for wishful thinking on the part of hospital executives and physicians. Rather than accept the inevitability of reducing excess capacity and incomes, providers cling to self-serving myths about managed care's strategic direction. H...
