Performance Testing for OTA
PCTEST CONFIDENTIALPerformance Testing for OTA. Operator Driven Focus in Areas not Addressed by Certification: Bluetooth, NFC, GPS, Co-Existence, Internal Desense at Operator Specific Channels Alternate Metrics (Near-Horizon Partial Quantities, Antenna Efficiency, ECC, etc.) Alternate Test Environments (Reverberation Chamber w/ and w/o Channel Emulator, Small Chambers, etc.) Alternate Device Positioning, Alternate Phantoms (Ground Plane, Body-Worn, Lap/Table, etc.) Targeted OTA Tests/Metrics based on Device Type Operator Specific RF Channel Configurations and Channels Operator Specific Pass/Fail Requirements Goal is to Derive Expected Network Performance/Coverage from Performance Test Certification Testing Metrics may not Allow for a Full Evaluation
