Pivotal Commware develops software-defined antennas and radios that use Holographic Beam Forming™ to increase network speed, capacity and spectral efficiency. For network operators, Pivotal's reconfigurable beams can follow mobile users in real time using the lowest cost, size, weight and power consumption (C-SWaP) envelope available. Pivotal's holographic beamforming focuses transmitted power at the intended recipient(s) as opposed to the omnidirectional DSP based space-time coding used in digital beamforming. Holographic beamforming provides a solution to the need for greater spectral efficiency driven by the insatiable demand for wireless data. Through holographic beamforming, it is possible to simultaneously reuse the same spectrum in a given space. Like the beams from several spotlights illuminating discrete objects on a stage, holographic beamforming antennas are capable of focusing their radiated power on separate targets without illuminating adjacent users. Unlike current cellular systems that utilize antennas that form 60-90 degree stationary sector beams, holographic beamforming permits more of a one-to-one communications protocol between base station and user. This technique preserves the spectral hygiene of the cell and allows multiple concurrent transmissions using the same frequency without interference. This allows abundant spectrum reuse and higher modulation rate signals for both stationary and mobile users.
