A surgical hub for use with a surgical system in a surgical procedure performed in an operating room, wherein the surgical hub comprises: non-contact sensors ; means for determining locations of devices of the surgical system located within a pairing range of the surgical hub by assessing transmission radio signal strength and direction; and a control circuit configured to: initially, determine bounds of the operating room based on measurements performed by the non-contact sensors; after the initial determination, detect devices of the surgical system located within the pairing range of the surgical hub; determine a location of a detected device using the means for determining the locations of devices of the surgical system; determine whether the detected device is located within the determined bounds of the operating room; pair the surgical hub with the detected device if it is determined that the detected device is located within the determined bounds of the operating room; determine whether the detected device located within the determined bounds of the operating room is a second surgical hub; and establish a control arrangement with the detected second surgical hub located within the bounds of the operating room, wherein the control arrangement is a master-slave arrangement or a peer-to-peer arrangement. non-contact sensors ; means for determining locations of devices of the surgical system located within a pairing range of the surgical hub by assessing transmission radio signal strength and direction; and a control circuit configured to: initially, determine bounds of the operating room based on measurements performed by the non-contact sensors; after the initial determination, detect devices of the surgical system located within the pairing range of the surgical hub; determine a location of a detected device using the means for determining the locations of devices of the surgical system; determine whether the detected device is located within the determined bounds of the operating room; pair the surgical hub with the detected device if it is determined that the detected device is located within the determined bounds of the operating room; determine whether the detected device located within the determined bounds of the operating room is a second surgical hub; and establish a control arrangement with the detected second surgical hub located within the bounds of the operating room, initially, determine bounds of the operating room based on measurements performed by the non-contact sensors; after the initial determination, detect devices of the surgical system located within the pairing range of the surgical hub; determine a location of a detected device using the means for determining the locations of devices of the surgical system; determine whether the detected device is located within the determined bounds of the operating room; pair the surgical hub with the detected device if it is determined that the detected device is located within the determined bounds of the operating room; determine whether the detected device located within the determined bounds of the operating room is a second surgical hub; and establish a control arrangement with the detected second surgical hub located within the bounds of the operating room, wherein the control arrangement is a master-slave arrangement or a peer-to-peer arrangement. <EOS>
