Abstract

With the rollout of LTE networks the energy consumption of wireless networks will further increase. We study the impact of power amplifier improvements in combination with scheduling strategies for traffic profiles expected around 2015. We compare a scheduling policy with adapted bandwidth (capacity) using a power amplifier with adaptive operation point vs. a micro DTX scheduler using a power amplifier with a deactivation mode. In times of low traffic up to 30% of energy saving can be achieved, over a day 13% to 24% are achieved.
