Devices, traces, analysis and data

Commercial off-the-shelf smartphones running Android 10 or later, without root access. The KPIs exposed depend on the modem and on the permissions granted. Advanced KPIs — MCS, rank, BLER, RRC and NAS signaling — come from test-device diagnostic traces, analyzed in AKCELL Analyzer.

Test-device diagnostic traces, measurement files from third-party drive test tools, IP captures and AKCELL Mobile sessions; traces from dual-SIM devices are split by subscription. The detailed list of formats is given in the AKCELL Analyzer datasheet.

Each second of data transfer whose downlink throughput is below the threshold receives the first verified cause, in a documented order: mobility, coverage, radio quality, BLER, share of allocated slots, RB, rank, MCS. Thresholds are adjustable; a second with no obvious radio cause is classified as “undetermined”, never forced into a category.

Yes. Coverage hole, degraded SINR, high BLER, pilot pollution, dominant neighbor without handover, uplink power limitation, ping-pong: each threshold (level, window, duration) is set in Tools › Event thresholds. Signaling events are linked to the message that carries them.

No. AKCELL Mobile records sessions on the device, and the fleet communicates locally, between devices in close proximity. AKCELL Analyzer processes traces on the user’s workstation. Only the network tests (with the test servers) and the base map (with the map tile server) exchange traffic; no measurement is sent to them.

The floor plan of each level is imported into AKCELL Mobile and calibrated on two reference points. The route is defined in advance — façades, circulation areas, stairwells, elevators — and each waypoint is placed on the plan. In AKCELL Analyzer, the walk is replayed on the plan and colored by KPI; dominance and the margin over the best neighbor are read zone by zone.

AKCELL Analyzer reconstructs VoLTE calls and IMS registrations from the SIP messages, reads the call release causes and estimates perceived quality from the transport (loss, jitter, delay) using the ITU-T E-model. Standardized perceptual methods (ITU-T P.863), which require recording the audio signal, are not offered.

Yes: preparation and execution of measurement campaigns, indoor acceptance testing, analysis of existing traces with an expert report — root cause, recommendations and corrective action.
