Abstract:
Laser communication links in space are attractive alternatives to present-day microwave links. This tutorial
describes the basic concept and the functions of an optical terminal on board a spacecraft. It points out the differences
between free-space optical links on one hand and glass fiber systems and microwave directional links on the other
hand. The requirements on data transmitters and receivers as well as on optical antennas and pointing, acquisition and
tracking mechanisms are discussed. Typical application scenari ....etc

Smart Sensor Networks: Technologies and Applications for Green Growth:


Fields of application of wireless sensor networks:

There are numerous different fields of application of sensor networks. For example, forest fires can be detected by sensor networks so that they can be fought at an early stage. Sensor networks can be used to monitor the structural integrity of civil structures by localising damage for example in bridges. Further, they are used in the health care sector to monitor human physiologi ....etc
