System and method for pairing devices in a gym environment

A system comprising:

• a server computer comprising at least one processor and at least one memory configured to store training data of one or more users;
• a plurality of data collector devices, each of the plurality of data collector devices being associated with a gym device or an exercise spot of a gym,
• wherein
• each data collector device comprises a wireless communication unit, and a memory configured to store training data of a user;
• one or more time-of-flight positioning units configured to be disposed at fixed locations in the gym and conduct time-of-flight positioning;
• one or more mobile tag devices, each mobile tag device comprising a time-of-flight positioning unit configured to conduct the time-of-flight positioning together with the time-of-flight positioning units at the fixed locations;
• and
• one or more wearable devices, wherein each wearable device is associated with one of the one or more mobile tag devices, and each wearable device comprises a wireless communication unit, and a memory configured to store training data of the user,
• wherein the system is configured to perform operations comprising:
• tracking locations of the one or more mobile tag devices with respect to the data collector devices in the gym as a result of the time-of-flight positioning;
• determining, on the basis of the tracking, whether or not a location of a mobile tag device is within a pairing area of a data collector device;
• and
• when the location is determined to be within the pairing area, triggering establishment of a wireless connection between a wireless communication unit of the data collector device and a wireless communication unit of a wearable device associated with the mobile tag device, and transmitting training data between at least two of the data collector device, the wearable device, and the server computer.
