We study how the distribution between two types of tilt, electrical and mechanical, affects path gain and cell edge, peak, and average throughput.
By using antenna tilting technique, a significant improvement in the desired SINR, average throughput and sum data rate within the cell can be observed as well ...
Results highlight the point that changes in antenna height and tilt angle results in variations in the signal coverage and path loss of the network.
Abstract—Antenna tilt is one of the most important perfor- mance tuning parameters of a cellular network, since it has a strong impact on the inter-site ...
With mechanical tilt the loss compared to the optimal tilt combination, i.e. pure electrical tilt, is up to 25% for cell edge and up to 10% for mean throughput.
People also ask
What is the difference between electrical and mechanical tilt antenna?
Mechanical Down-Tilt: where the antenna is tilted as a whole, including all its segments. Electrical Down-Tilt: where there is adjustment of phase of the control signals given to individual segments of the antenna.
What is the electrical tilt of an antenna?
Electrical tilt is the process of adjusting the phase of the signal that is fed to the antenna. This can be done by using a phase shifter. Electrical tilt is typically used to improve the gain of an antenna in a specific direction.
What is the tilt angle of an antenna?
Antenna tilt is defined as the angle between the main beam of the antenna and the horizontal plane. It is measured in degrees and can have positive and negative values.
What is mechanical down tilt?
Mechanical downtilt: This process involves physically adjusting an antenna's pole-mount brackets, using a digital level set against the back of the antenna to obtain an accurate measurement.
