CellScope Pro — Free Browser-Based RF Planning & Learning Platform for 4G/5G

CellScope Pro is a free browser-based RF network planning and learning platform for 4G LTE and 5G NR coverage prediction, site design, PCI planning, and RF engineering education. Built by RF engineers for engineers, students, and small operators — calibrated against 3GPP TR 38.901 and ITU-R P.1812-7 standards, with drive-test calibration support.

Honest positioning: CellScope Pro is not a replacement for Atoll, Planet, or ASSET in enterprise operator workflows. Those tools have decades of investment in geodata, live-network integration, and vendor support that we do not match. We are a credible learning/planning platform for outdoor macro, small-cell, and educational use, with a transparent engine and exportable engineering reports.

Engineering Foundations & Standards

Every prediction is computed using physics from published standards (not black-box marketing math):

• 3GPP TR 38.901 — UMa / UMi / RMa propagation, LoS probability, K-factor (0.5–100 GHz)
• ITU-R P.1812-7 — Path-specific terrestrial propagation (30 MHz–6 GHz)
• ITU-R P.526 — Knife-edge diffraction (single + multiple obstacles)
• ITU-R P.452 / P.676 / P.838 — Interference, atmospheric absorption, rain attenuation
• ITU-R P.2109 / P.2108 / P.1238 / P.2040 — Building entry, terminal clutter, indoor, materials
• 3GPP TS 36.213 / 38.213 — UE open-loop power control (UL OLPC)
• 3GPP TS 36.214 / 38.215 — RSRP, RSRQ, RSSI, SINR measurement definitions
• 3GPP TS 36/38.211 — PCI groups, NCS for PRACH
• 3GPP TR 36.819 — CoMP / Joint Transmission cell-edge gain
• 3GPP TS 36/38.104 — BS noise figure, ACLR (in-band emissions)

23 propagation models supported. Full formulas, assumptions, and references are listed in the in-app Methodology & Standards section of the generated PDF report.

Geodata & Terrain

• Terrain DEM: SRTM 30m elevation tiles (AWS S3) with Delta-Bullington diffraction
• Clutter: ESA WorldCover 10m land-classification (auto-fetched per area)
• Building heights: OpenStreetMap (OSM) extruded buildings with material database for ray tracing
• 3D Ray Tracing: multi-bounce facade reflections + rooftop diffraction + material-aware penetration loss (concrete, brick, glass, drywall, metal, wood) with frequency scaling
• Custom DEM/clutter import: GeoTIFF + Shapefile (DBF + PRJ reprojection across WGS84 / Web Mercator / UTM)

Drive-Test Validation & Calibration

Predictions can be calibrated against measured RSRP from real drive tests:

• CSV / KML / GPX import with automatic header mapping
• Per-clutter auto-calibration — one click computes mean (measured − predicted) RSRP delta per clutter type and applies as a path-loss offset
• Linear least-squares calibration for SPM K-factors (K1–K7) with reported RMSE
• Gradient-Boosted Tree (GBT) calibration for non-linear residuals
• Confidence overlay layer — per-pixel reliability score flags areas where drive-test verification is recommended

A live mobile drive-test PWA at dt.html records GPS + RSRP estimates in the field and exports GPX for import.

Coverage Prediction

RSRP, SINR, RSRQ, throughput, best-server, UL RSRP/SINR, pilot-pollution, confidence, and composite layers. Capacity-aware SINR with per-cell PRB load. Carrier Aggregation throughput across same-site cells. UE-height-aware (handheld, vehicle, drone, CPE).

Site Planning & Design

Manual placement, hex grid generator, CSV import (with operator-realistic per-cell custom frequency override via resolveBand()), Atoll-style antenna pattern upload (.msi/.ant/.txt/.pat), 138 worldwide cellular bands with regional filter (FCC/CEPT/TRAI/ARIB).

PCI / PRACH / Frequency Planning

• DSatur graph coloring + Tabu Search PCI assignment
• Mod-3, Mod-4, Mod-6, Mod-30 conflict detection
• NCS auto-calculation from cell-range (TS 38.211)
• PRACH config index (0–63), FDM, SSB-RO mapping, restricted set (Type A/B)
• Joint Multi-Band AFP with CA-aware grouping
• Per-cell PCI/AFP locks for legacy preservation

Analysis Tools

• Link Budget Calculator — MAPL, cell range, ISD with limiting-link analysis
• Pilot Pollution layer — auto-paints overshooting zones (servers within 3 dB on same freq)
• Interference Matrix — C/I per cell pair with verdict
• Coverage Gap Analysis — top-15 holes < -110 dBm with coordinates
• Handover Boundary Stats — per-cell pixel ownership, overshoot detection
• Tilt Optimization — Find optimal electrical tilt per cell
• Monte Carlo Simulation — Statistical coverage probability with shadow fading
• EIRP Regulatory Audit — FCC / CEPT / TRAI / ARIB caps with PASS/EXCEEDS verdict

Optional Modules

• 3D Network Visualizer — SRTM terrain + OSM building extrusion + time-of-day sun arc
• Indoor Planning — wall/floor penetration with material library (educational depth, not iBwave depth)
• Backhaul Planning — Microwave + fiber routing with BOM
• Network Slicing (URLLC/eMBB/mMTC) visualization
• CoMP Analysis — Joint Transmission cell-edge gain modeling
• Vendor MML Export — Huawei MOD CELL, Ericsson NETCOOL lset, Nokia RAML

Known Limitations

• Live-network OSS/PM integration is on the roadmap, not shipped today
• Indoor planning is educational depth — not a substitute for iBwave / Ranplan for stadium / mall / DAS specialist work
• Geodata is open-source (SRTM 30m, ESA 10m, OSM) — commercial sub-meter geodata is available through Atoll/Planet vendor agreements
• Production planning requires drive-test calibration before commit. Run "Per-Clutter Auto-Calibrate" from the Drive Test menu
• Vendor SLA / support contracts not offered — community support via GitHub
• Always validate against field measurements before site acquisition or capex commitment
