Green ICT

  • 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
    • Joint paper: S. Lambert, M. Deruyck, W. Van Heddeghem, B. Lannoo, W. Joseph, D. Colle, M. Pickavet, P. Demeester, "Post-Peak ICT: Graceful Degradation for Communication Networks in an Energy Constrained Future", IEEE Communications Magazine, Vol. 53, No. 11, pp. 166-174, November 2015.
Research projects: 
  • iMinds GreenWeCan
  • Bilateral projects with LNE (Environment, Nature and Energy department of the Flemish Government)
  • Politecnico di Torino
  • LNE (Environment, Nature, and Energy department of the Flemish Government)
Tools and Valorisation: 
  • Power measurements on operational base stations
  • Capacity-based deployment tool for green wireless access networks
    • Responding to the number of active users and their instantaneous bit rate request by introducing sleep modes for the base stations in the network
    • Green wireless access networks: optimized towards power consumption, towards human exposure or towards both power consumption and human exposure
    • Based on 3D information about the environment

    Output of the capacity-based deployment tool
