Draft:Angle of departure

Angle of Departure (AoD) refers to the direction from which a signal, such as radio, optical, or acoustic, departs. In AoD, the receiving device calculates its position in space by employing various methods, including triangulating angles from multiple beacons and their known positions. The primary goal is to determine the azimuth angle of a distant emitter.

Measurement
Measuring AoD involves using antenna arrays to precisely direct transmitted signals. . This process includes sending signals through an antenna array and receiving them through a single antenna on the receiving device. The data is analyzed by the receiving device, enabling it to accurately calculate the angle of departure

Applications
AoD finds applications in various communication scenarios, particularly in systems requiring precise positioning. In wireless communication, AoD is employed for localization purposes, enabling devices to determine their spatial coordinates based on multiple beacons with known positions. This is especially relevant in emerging technologies such as the Real-time Locating System (RTLS), where users depend on accurate location information for navigation and wayfinding within complex indoor settings.
