Dynamic variation of power per antenna to facilitate beamforming of antenna array
摘要:
Methods and systems are provided for dynamically adjusting the beamform of an antenna array. A first beamform produced by an emission from a first antenna and an emission from a second antenna are determined, each of the first antenna and the second antenna having separate power supplies. Positions of user devices served by the cell of the antenna array are determined and compared to the first beamform. If it is determined that a second beamform would provide better coverage to any one or more of the user devices served by the cell, any one or more of the power supplies to individual antennas may be modified. Any one or more power supplies may utilize changes in the phase and/or amplitude of the power supplied to an antenna to change the emission of at least one antenna, producing a second beamform. The second beamform, in particular, may permit dynamic targeting of various vertical distributions of user devices within the cell.
