Dear all;
I am an originally signal processing expert working on "positioning in smart cities" for IoT using bluetooth 5.1. As part of our new tasks, we are to evaluate the possibility of establishing a new BLE link for the purpose of positioning (indoor and outdoor). Improving on our existing technology, we desire to make use of the special feature of BLE 5.1, namely, the use of antenna arrays and direction finding, to further enhance the accuracy of current positioning techniques.
I was wondering to inquire about the following matters, regarding the new SoC "nRF52811" and possible integration of it into IPS (Indoor Positioning Systems), RTLS (Real-Time Localization Systems) or BLE Beacons.
1- Is the antenna array capability already implemented/tested on the development/evaluation board for nRF52811?
Within same question, does the development/evaluation board come with the antenna arrays for sell?
2- Are there algorithms and techniques implemented in the embedded SDK concerning the estimation of AoA or AoD (direction findings)? Has anyone seen a reliable BLE-based positioning system using nRF52811, which makes use of direction finding to improve on accuracy?
3- Has anyone observed any measures of the accuracy or the results, such as that in terms of the error in localization or angle estimation?
I will be so grateful if anyone can lend help with these concerns.
Cordially,
M. Parchami
