WIRELESS COMMUNICATIONS IN A TREE CANOPY

Wireless Communications in a Tree Canopy

The wireless communications in a tree canopy is essential for pre-harvesting control of fruit productions. To efficiently communicate between a sensor node and a sink node, channel characteristics in a tree canopy must be well-established. In this paper, propagation channel characteristics at the frequencies of 2.45 and 5.2GHz have been estimated for designing a wireless communication system in...

Polarization in Wireless Communications

Wireless communications exploits the electromagneticmedium,which is intrinsically polarization-sensitive. Much wireless technology, however, has been devised without explicit consideration of polarization. Past decades of wireless technology has mainly exploited the dimensions of time, frequency and space. As such, polarization is a logical next step in this progression. This special issue focu...

Wireless Communications in Substations

Wireless Communications

The field of wireless communications has been in existence since the first humans learned to communicate. In early days of civilization humans would transmit notices of important events such as enemy invasions or royal births through the sounding of horns or the lighting of fires. While simple messages could be effectively transmitted in this manner, in order to communicate over long distances ...
