Latest Patents

Andrew holds a patent for "Radio frequency enclosure attenuation calibration." This patent discusses techniques for determining calibration data associated with an RF testing environment. For instance, an RF signal can be input to the RF enclosure and selectively applied to discrete attenuators. The attenuators can adjust the strength of the signal, and various user equipment (UEs) located within the RF enclosure can measure the signal strength. A plurality of measured reference signal received power (RSRP) values can be determined by multiple UEs associated with a specific attenuation level. Different attenuation levels can be measured, and an average attenuation can be calculated for attenuation steps. Measured attenuation steps can be extrapolated to other levels to expedite the calibration process. Subsequently, a testing plan can be applied to the RF enclosure, and the calibration data can be utilized to ensure accurate signals for testing UEs.
