A method and system for selecting a thermally optimal airlink for a portable computing device includes monitoring a temperature of the portable computing device as well as determining if the portable computing device has reached a threshold temperature range. Next, an estimated volume of data to be sent over one or more airlinks may be calculated in addition to determining an estimated duration for the data using one or more airlinks. A quality of service needed for the data in connection with the one or more airlinks may be determined. With this estimated data, one or more available airlinks for the data to be transmitted may be compared. After this comparison, one or more thermally optimal airlinks may be selected based on the estimated volume, estimated data rate, and estimated duration. Determining if the portable computing device is proximate to an operator may be used when considering airlinks.
