Abstract

A method can include determining whether, based on job data and in completing a first job of jobs with a transmission at a fundamental frequency, a harmonic frequency of the fundamental frequency satisfies a second job of the jobs, and transmitting the transmission with the fundamental frequency and the harmonic frequency to complete the first and second jobs, respectively and simultaneously.
