Initial 3GPP efforts have focused on the ability todifferentiate machine-type devices This allows the operator to selectively handle such devices
in overload situations
Radio-level optimisations to enable implementationof low-cost LTE M2M devicesWork moving towards generic solutions due to
divergence of M2M traffic patterns UE power consumption optimisation Optimisation for small data transmission
