Abstract
An accessory device may establish a short range link to a companion device, and the accessory device may use the companion device as a proxy to conduct a data session over a cellular network. Based on a latency requirement associated with the data session and/or a signal strength of the short range link, the accessory device may dynamically determine to transition its cellular radio from a powered-off mode to a low power mode.
