## Abstract

A method for establishing a radio connection includes selecting a first radio access technology for a first phase of a multi-phase radio connection establishment process to minimize power consumption at a remote device, and participating in the first phase of the multi-phase radio connection establishment process. The method also enables establishing and using a radio connection with the first radio access technology that is selected independently from a selection of a second radio access technology used in a second phase of the multi-phase radio connection establishment process, wherein the second phase may be relayed or direct data communications over the established connection in the first phase between the wearable device and its peer (relay) devices or network equipment.
