High floor: restoring 5G DAS dominance over the macro cells

On the 14th floor, the indoor cell does not dominate at the façades: the floor plan colored by SINR, the delta to the best neighbor and the cell inventory identify the macro cells involved, then validate the added antennas.

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.
