Motivation for this work is the development of a new satellite air interface for a low data rate massive access network in the context of machine-to-machine communications (M2M)/Internet of things (IoT) applications. For this purpose, this chapter considers energy efficiency at the user terminal and gives an evaluation of hardware-related aspects for an energy-efficient air interface and introduces a hardware concept involving energy harvesting in combination with an intelligent energy and system management. Typically, the performance of air interfaces is measured in terms of throughput, transmit error performances, etc. However, we evaluate for energy efficiency, an additional hardware-related aspect, which indicates the joint energy efficiency of hardware and transmission scheme. In particular, conventional continuous transmission of a message is opposed to discontinuous transmission by telegram splitting, as specified for the telegram splitting ultra-narrowband (TS-UNB) technology standardized by European Telecommunications Standards Institute (ETSI). Evaluations show that discontinuous transmission exploits the hardware components in a more efficient way than continuous transmission. This results in an extended use of the battery, which translates into a longer lifetime of the user node.
