Key Takeaway
HiCellTek enables indoor DAS coverage validation (airports, malls, stadiums, hospitals) directly from an Android smartphone. Import floor plans, perform point-by-point walk tests, and generate RSRP/SINR heatmaps in real time. Expected outcome: 3 to 5x faster DAS validation compared to legacy scanner tools, with immediately actionable data. Key modules: Indoor Walk Test, RF Monitor, Cartography.
Indoor DAS Coverage Validation with HiCellTek
Distributed Antenna System (DAS) installations in critical buildings require rigorous indoor coverage validation. This use case shows how HiCellTek transforms the DAS acceptance process by making it faster, more accurate, and fully mobile.
The indoor DAS context
High-density buildings require Distributed Antenna Systems to ensure homogeneous 4G/5G coverage indoors. After installation, every zone must be validated through point-by-point measurements to verify that contractual RSRP and SINR thresholds are met. Traditionally, this requires dedicated RF scanners, a laptop for data collection, and several days of post-processing to generate heatmaps and the acceptance report.
Indoor DAS validation challenges
No GPS indoors
Standard drive test tools rely on GPS for measurement geolocation. Indoors, GPS signal is absent or degraded, making automatic spatial correlation of KPIs impossible.
Heavy, cumbersome equipment
Professional RF scanners and collection laptops weigh several kilograms, a burden when walking through large buildings like airports or shopping centers. Technician fatigue impacts measurement quality.
Lengthy post-processing
Generating heatmaps and the acceptance report requires data transfer to PC, import into specialized software, and hours of processing. Days pass between measurement and deliverable.
Disputes over results
Without precise geolocated data on floor plans, discussions between DAS installers and operators about threshold compliance are frequent and time-consuming.
The HiCellTek solution for DAS acceptance
HiCellTek transforms the Android smartphone into a professional indoor validation tool. The Indoor Walk Test module allows importing building floor plans and performing geolocated point-by-point measurements directly on the plan.
Import floor plans (PNG, JPEG, PDF), manual or assisted positioning of measurement points on the plan, automatic radio KPI collection at each point. RSRP, RSRQ, and SINR heatmap generation directly on the floor plan.
Real-time RSRP, RSRQ, SINR, and RSSI measurement of serving and neighbor cells. Immediate identification of zones below contractual thresholds during the walk test.
Measurement overlay on building plans with data interpolation between measurement points. High-resolution heatmap export for the acceptance report.
Real-time RRC/NAS decoding to verify handovers between DAS antennas, reattachments, and indoor cell configurations. Immediate diagnostics when anomalies arise.
Simplified workflow
The technician imports the floor plan into the app, defines planned measurement points, then walks the building tapping their position at each point. KPIs are collected automatically and the heatmap builds in real time on the smartphone screen. At the end of the walk test, the acceptance report is ready to export, no post-processing needed.
Expected results
Based on measured capabilities of the HiCellTek platform.
Complete DAS validation in hours instead of days with legacy tools.
Heatmaps and reports generated in real time, directly in the field.
A single Android smartphone replaces RF scanner + laptop + PC software.
Cloud synchronization for immediate validation by the operator.
