The basis for Socowave's innovative beamforming solutions is its unique wideband calibration technology. It synchronises all transmitters and receivers from an inter-path; phase, amplitude and timing perspective, thereby producing a highly coherent platform for beamforming.
In wide channel systems (5MHz upwards), calibration of transmit signals is essential for optimal performance. The video below shows the random nature of transceiver lineup clocking and its impact on the propagated signal, if uncontrolled.
3-Way calibration ensures that an array-based transceiver systems do not become an EVM contributor, rather it enables SDMA functionality.
