“So we actually have patented hardware with multiple radios inside of it, and those radios, when you place the devices in in the right configuration around a room or a space, hallways, whatever, a stadium, A hotel, a casino, a hospital, you name it, a retail store. It can actually determine down to, I call it show or we call it shoulder to shoulder accuracy of where everyone in that particular building is located or where the devices are in that building.”

Assessment

On February 19, 2019, Robert Frederick (then-CEO of Sirqul, Inc., which is phonetically referred to and branded as 'Circle') claimed that his company held patented multi-radio hardware capable of tracking people and devices indoors to 'shoulder-to-shoulder' accuracy. Patent records confirm that Sirqul, Inc. and Frederick held granted patents for multi-radio mesh and socket hardware (e.g., US Patent 9,071,603 granted in 2015, US Patent 10,054,933 granted in 2018, and subsequent patents US 10,251,247 and US 10,383,201). Furthermore, published technical specifications for Sirqul's Edysen multi-radio hardware documented triangulation tracking accuracy 'down to the foot' (~0.30 meters), fulfilling the sub-meter / shoulder-to-shoulder accuracy threshold.

USPTO patent records show Sirqul, Inc. (with Robert Frederick as inventor) holds patents covering multi-radio mesh hardware and inter-device tracking (e.g., US 9,071,603, US 10,054,933, US 10,251,247, and US 10,383,201).
Product specifications for the Sirqul Edysen multi-radio device line document sub-meter indoor positioning capabilities 'down to the foot' (~0.30 m) using multi-radio triangulation across Wi-Fi and Bluetooth BLE.
