where is the transmitter's power level, is the transmitter's antenna gain in the direction towards the receiver, is the receiver's antenna gain in the direction of the transmitter, is the transmitter's cable attenuation, is the receiver's cable attenuation, and is adaptive transmission path loss, which we will discuss carefully later.
Initially, the northern direction of the transmitter stations is parallel to the positive direction of the y axis.
where (boldsymbol {hat {k}}) is a unit vector that gives the direction of departure from the transmitter array, and (boldsymbol {hat {kappa }}) is a unit vector that gives the direction of arrival to the receiver array.
Resolving this dual solution would be impossible without knowing the direction of rotation of the transmitter.
The direction of travel of a transmitter is stated in Definition 5 as the angle between consecutive positions in Euclidian space.
We establish a mobility path in our vehicular scenario as a sequence of vehicular layout coordinates over time, along with a mobile transmitter's direction of travel at every point.
This is achieved using smart antenna technology that adapts to environmental changes by focusing the receiver antenna in the direction of the incoming power from the transmitter using beam forming and steering.
In a better approximation the power level and the antenna characteristics, e.g. the direction of the main beam of the transmitter, as well as the reflections and absorptions along the path from antenna to the home of the participant, as the housing parameters should be taken into account.
Number of transmitter antennas.
All published epidemiologic studies of transmitter exposures have based exposure assessment on distance from the transmitter.
