Degraded 5G throughput on an urban route: three causes, three actions

Interference from an overshooting cell, rank stuck at 1 due to a faulty RF branch, a coverage edge: low-throughput cause analysis separates the three and quantifies the gain from the corrections.

Median DL throughput over the route: 220becomes424 Mbit/s
DL layers on the repaired sector: 1becomes4
Pilot pollution alerts: 6becomes0

Uplink noise rise on a shared DAS: diagnosing passive intermodulation

Excellent downlink coverage, an uplink that collapses at times: three tests at a stationary point and one correlation are enough to identify passive intermodulation before any technician is dispatched.

UL throughput, simultaneous test: 1.0becomes15.5 Mbit/s
PUSCH transmit power: 23becomes11 dBm
Correlation of DL throughput with UL power: 0.93becomes−0.37
