5G Wireless Standard Design

A: The right call prevents rising PIM by stopping electrochemical potential from building under salt-laden moisture. Uniform oxidation ignores the electrolyte and metal pairing that sets the cell. Stress corrosion cracking needs sustained stress and specific alloys that aren't present here. Fretting happens, but it doesn't explain the monotonic IM growth seen without repeated mating cycles.

A: The chosen value preserves physics by summing power linearly across carriers before applying losses and gain. Adding 7 dB blindly skips the linear domain and overstates radiated power. Scheduler assumptions don't remove simultaneous average power in a compliance sense. Averaging across bandwidth confuses spectral density with total radiated power.

A: Reading it this way explains how the unit adapts band edges without violating isolation. An RF sampling port would be shown as a coupled branch with power levels. Redundant RF paths are drawn as solid parallel lines with ports. External calibration loops are called out with connectors and test notes.

A: This option directly reduces out-of-band emissions that drive the complaint while staying within spectral masks. Trading antenna gain for PA power leaves ACLR unchanged at the port. Duplexing mode change isn't available in n78 deployments. Downtilt helps geometry but doesn't fix spectral regrowth seen at the victim receiver.
