TR Component Azimuthal Adjustment for Wireless Network Interference

Solution Overview

Problem

In wireless telecommunications networks, active state user equipment often experiences reduced performance due to intra-cell interference, which can be attributed to overlapping network signal footprints from adjacent TR components, leading to suboptimal throughput and signal-to-interference-plus-noise ratio (SINR) values.

Innovation Solution

The method involves adjusting the azimuthal setting of a TR component to shift the network signal from a first footprint to a second footprint, reducing overlap and improving performance by mechanically shifting the TR component in the azimuthal direction, thereby altering the sector power ratio (SPR) and enhancing throughput and SINR for active state user devices.
