line of sightautomated motorized line of sight control of antennas is discussed in this paper which is an advanced technique. By using automated system between the antennas to obtain maximum signal strength and reduce the over all fading diffractions between the two antennas.Hassan Muse Warsame...
A wireless multiple-input multiple-output (MIMO) multiplexing system consists of multiple transmit and receive antennas. The channel capacity of such systems does not merely depend on the number of degrees of freedom (DoF) it can support, but also on their gains, represented by the singular valu...
In obtaining the radar horizon equations, it is common practice to assume a value for the Earth's radius that is 4/3 times the actual radius. This is done to account for the effect of the atmosphere on radar propagation. For a true line of sight, such as used for optical search and ...

Line of sightRadio transmissionTilting the antennas up to obtain 2 dB loss (for each antenna) over maximum gain during steady signal conditions is shown to reduce fading over this particular path. The technique should also work on other paths where sufficient angular separation between the direct ...
First the two basic types of smart antennas, adaptive and phased arrays are described and then their current use and proposed use in future wireless systems is discussed. A smart antenna is therefore a phased or adaptive array that adjusts to the environment. That is, for the adaptive array,...
The present invention relates to a method for alignment of a first node with at least one secondary node in a wireless communication network. The first node includes first node antenna beams with corresponding designated pointing angles. For each such beam, the method comprises the steps of, for...
For each such beam, the method comprises the steps of, for each secondary node: directing a first node antenna beam in its designated pointing angle; using a secondary node antenna beam where objects can generate signal reflections/diffractions; and detecting at least one signal property of ...
