Green ICT
Competences:
- Power consumption model for different type of base stations and various 3G, 4G, and 5G wireless technologies (GSM, UMTS, HSPA, WiMAX, LTE(-Advanced))
- Influence of traffic, MIMO, sleep modes, etc. on the base station's energy efficiency
- Development of wireless access networks optimized towards power consumption or exposure for human beings
- Joint-optimization of power consumption and exposure for human beings in a wireless access network
- Development of strategies for reducing the impact of renewable energy shortages in wireless access networks powered by renewables and the traditional power grid
- Evaluating the performance of wireless access networks in post-peak and energy-constrained future scenarios
- In collaboration with the IBCN research group
