  • Whatisbeyondthese values?There’s a hugepotential for more efficient elements in all parts of the network. The research effort willbe immense. Only a collaboration between the main playerswilllead to achieving the goal.
  • How an antenna connects to an end-user.The wireless signal is broadcast equally to an entire sector when connecting to an end-user.
  • How an antenna connects to an end-user.The wireless signal is broadcast equally to an entire sector when connected to an end-user. Energy use is high. Most energy is wasted.
  • Antenna prototype simulates action of current antennas. The wireless signal is broadcast equally to an entire sector when connected to an end-user. Energy use is high. Most energy is wasted.Only one antenna column is powered to simulate a call to an end-user.
  • Simulated action of the prototype Large Scale Antenna System.The Large Scale Antenna System focuses the wireless signal to the end-user. Energy efficiency is improved 16X!All antenna columns are powered to simulate a call to an end-user.
