Making 4G networks loT and M2M-ready

摘要

Features such as power saving mode (PSM), extended discontinuous reception (eDRX) cycles and coverage enhancement (CE) can tune the wireless interface to the needs of loT applications. An optimised core architecture that also allows non-IP communications will further help to adapt 4G networks for the Internet of Things. To meet the specific performance and availability requirements, the right features and parameters need to be selected and all communications layers must work together perfectly. This creates a need for end-to-end application testing, in order to optimise performance parameters (for example, power consumption and reaction times).
