1. A method for outputting data for storage by a user device in a distributed storage network (DSN), the method comprising: processing the data into a plurality of sets of encoded data slices using an error coding dispersal storage function, wherein a data segment of the data is encoded into one of the plurality of sets of encoded data slices; identifying distributed storage (DS) units of the DSN for storing the plurality of sets of encoded data slices, wherein a first DS unit of the identified DS unit to store a first encoded data slice of each set of at least some of the plurality of sets of encoded data slices, a second DS unit of the identified DS unit to store a second encoded data slice of each set of the at least some of the plurality of sets of encoded data slices; and a third DS unit of the identified DS unit to store a third encoded data slice of each set of at least some of the plurality of sets of encoded data slices; determining performance requirements regarding storing the plurality of sets of encoded data slices in the identified DS units; determining security requirements of the plurality of sets of encoded data slices based, at least in part, on vault information associated with the data segment; in accordance with the performance requirements and the security requirements, mapping the at least some of the plurality of sets of encoded data slices to particular wireless modules of the user device for substantially simultaneous wireless transmission of the at least some of the plurality of sets of encoded data slices to the identified DS units via one or more networks; transmitting, by a first wireless module of the wireless modules, the first encoded data slice of each of the at least some of the plurality of sets of encoded data slices to the first DS unit; transmitting, by the first wireless module, the second encoded data slice of each of the at least some of the plurality of sets of encoded data slices to the second DS unit; and transmitting, by a second wireless module of the wireless modules, the third encoded data slice of each of the at least some of the plurality of sets of encoded data slices to the third DS unit.
