Angle of Arrival - Bluetooth 5.1 Direction Finding Explanation

5 років тому

Our new software for Bluetooth 5.1 adds support for angle of arrival (AoA) and angle of departure (AoD). This feature enhances location services applications including indoor navigation, asset tracking, and point-of-interest mobile engagement. Learn more:

Thank you for everything

Hi @Silicon Labs, As you answer: "No, if phones want to implement AoD and receive beacons packets from multiantenna beacons and calculate the angle and elevation. In this case the phone “just” needs software that is able to do the angle calculation and does not need multiple antennas." Its mean, in this case, I can use a smartphone with Bluetooth version 5.0 or lowers and update/install software that is able to do AoD algorithms or need to have a phone with Bluetooth V5.1 to support AoD algorithms? Thank you for answer!

Hi, when do you guys think the direction finding development kit would be out for sale?

In this demo the asset-tracker and the locator is close to each other and in Line-of-sight (LoS). For any indoor positioning system the main problem is multi-path, reflection and when the object (asset-tracker or tag) and Locator (or anchor) are Non-LoS. How accurate the measurements in those condition for BT 5.1? AoA is very sensitive to distance and other reflection related issues.

I am wondering about the same thing. Guess I´ll have to get hands on such a system and test it myself.

you likely would need several roof mounted arrays to track a larger environment for best chances of LOS tracking of objects

Please have bluetooth 5.1 to both cell phones and gaming devices

Check 0:59. Direction display goes wild when he puts his hand on the tag probably blocking the signal

@neilyoung6671 3 роки тому

Exactly. Same procedure as last year. Wearing such a tag on your ass or on your jacket makes a significant difference :)

@slicex3408 2 роки тому

i don't see anything "going wild"

Impressive

I think it is repetitive question. 1. Does the AOA Implementation in mobile need to be upgraded new h/w(chip) and s/w( next version of oreo in case android)? 2. what is minimum requirement to implement AOD in mobile ? only mobile os upgrade can make AOD possible? if not, we need install new h/w compliant to BLE 5.1?

Hi, please see our direction finding landing page: www.silabs.com/products/wireless/learning-center/bluetooth/bluetooth-direction-finding?cid=nat-you-ble-012819 Or, visit silabs.com/community where you can ask our engineers questions directly. Thank you!

@azzamf.khayyat8072 5 місяців тому

so you determined the elevation and angle but the main issue so far regarding ble signlas is you can't accurately determinate the distance nor control it, as per our latest testings.

@DXenakis 5 років тому

Does this require for the future (Bluetooth 5.1 enabled) smartphones to have a new antenna design?

@ViralSilabs 5 років тому

Hi! Our Bluetooth marketing manager has this answer for you: Yes and no: Yes, if phones want to implement direction finding such as “find my keys” they will need to have multiple antennas. No, if phones want to implement AoD and receive beacons packets from multiantenna beacons and calculate the angle and elevation. In this case the phone “just” needs software that is able to do the angle calculation and does not need multiple antennas. If you have any more questions, please visit the community at community.silabs.com, where our engineers can talk directly!
