1. A gym device, comprising:
a radio apparatus, the radio apparatus comprising: phased antenna array comprising at least two phased antenna elements for wirelessly communicating heart activity data with exercise sensors; at least one processor; and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the radio apparatus to perform operations comprising: generating at least one antenna beam pattern with the at least two phased antenna elements, wherein at least one main lobe of the at least one antenna beam pattern is directed towards a gym device-specific exercise area, wherein the gym device-specific exercise area is an area in which the exerciser is located while exercising with the gym device; performing automatic pairing of the radio apparatus with an exercise sensor located in the gym device-specific exercise area, wherein the automatic pairing comprises:
identifying that the device to be paired with, among a plurality of different devices in a gym, is an exercise sensor, wherein the identification is based on an identifier received from the exercise sensor; andselecting the exercise sensor to be paired with from a plurality of exercise sensors in a gym on the basis of received signals strengths from the plurality of exercise sensors and by applying the at least two phased antenna elements in order to determine which exercise sensor among the plurality of exercise sensors is located in the gym device-specific exercise area; wherein the radio apparatus is further caused to perform operations comprising: communicating heart activity data wirelessly with the paired exercise sensor by applying the at least one antenna beam pattern and a short-range device-to-device technology, wherein the radio apparatus further comprises a wired data bus; and communicating the heart activity data with the gym device over the wired data bus. |
