Draft:Angle of departure

Submission declined on 17 January 2024 by Drmies (talk).

This draft's references do not show that the subject qualifies for a Wikipedia article. In summary, the draft needs multiple published sources that are:

in-depth (not just passing mentions about the subject)
reliable
secondary
independent of the subject

Make sure you add references that meet these criteria before resubmitting. Learn about mistakes to avoid when addressing this issue. If no additional references exist, the subject is not suitable for Wikipedia.

If you would like to continue working on the submission, click on the "Edit" tab at the top of the window.
If you have not resolved the issues listed above, your draft will be declined again and potentially deleted.
If you need extra help, please ask us a question at the AfC Help Desk or get live help from experienced editors.
Please do not remove reviewer comments or this notice until the submission is accepted.

Where to get help

Comment: The topic isn't clear, and the sourcing not enough. Drmies (talk) 18:06, 17 January 2024 (UTC)

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[edit]

Measuring AoD involves using antenna arrays to precisely direct transmitted signals.^[1]. 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^[2]

Applications[edit]

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.
