In this work the impact of the optical technologies and infrastructures on the reduction of the carbon footprint maintaining high level of broadband to the end user is discussed.
The increased interest in long lasting wireless sensor networks motivates to use Free Space Optics (FSO) link along with radio frequency (RF) link for communication. Earlier results show that RF/FSO wireless sensor networks has life time twice as long as RF only wireless sensor networks. However, for terrestrial applications, the effect of weather such as rain or snow on optical wireless communication...
The objective of this paper is to describe recent activities and investigations on free-space optics (FSO) or optical wireless and the excellent results achieved within SatNEx an EU-framework 6th programme and IC 0802 a COST action. In a first part, the FSO technology is briefly discussed. In a second part, we mention some performance evaluation criterions for the FSO. In third part, we briefly discuss...
Optical wireless links provide complementary behavior to the existing communication technologies like mmW or RF. It is admitted that the next generation of wireless communication networks (4G systems) will be based on multiple access technologies that will complement each other. Optical wireless is a very adequate access technology for future communication requirements and provides a huge bandwidth...
A dominant percentage of last mile Internet connections within entire Europe are realized with copper cable pairs (POTL) which are limited in bandwidth by cable length (attenuation) and the number of XDSL lines in a telecommunication cable (crosstalk). Exposed users often cannot get state of the art broadband Internet connections for these reasons and in addition also have to share existing bandwidth...
