Long Term Evolution (LTE) communications
systems are increasingly being used for remote applications where a battery life of 10 to 15 years can be specified. To ensure these demands can be met, accurate modelling
of power consumption is required. Existing models which decompose LTE power consumption focus on laboratory-only
measurements and use continuous transmission scenarios. The work presented shows that whilst these are valid for the continuous case, they are not relevant for Machine to Machine (M2M) activity on a live network. Under these
conditions, packet size is likely to be small in relation to protocol and system overheads, resulting in a dramatically increased and hard to model consumption of power. In addition,
network measurement and optimisation transmissions in supposedly low power idle periods threaten to further confound the issue.
