The ultimate professional reference tool for telecommunications engineers specializing in RAN (Radio Access Network).

Built by telecom engineers for telecom engineers, RAN Engineer Tool centralizes all the technical knowledge you need in the field: network parameters, KPIs, 3GPP diagrams, RF calculators, troubleshooting scenarios, and vendor documentation — all in one app that works completely offline.

📡 WHAT'S INCLUDED?
📋 Technical Parameter Database 500+ technical parameters organized by category: Mobility, RF Parameters, MIMO & Beamforming, Quality of Service (QoS), Random Access (RACH), Radio Resource Control (RRC), Interference Management, SON (Self-Organizing Networks), Carrier Aggregation, Network Slicing, and more. Each parameter includes a technical description, value ranges, KPI impact, and 3GPP references.

📊 KPI Dashboard Key performance indicators with reference values, calculation formulas, root cause analysis, and result interpretation. Covers accessibility, retainability, mobility, service quality integrity, and SON KPIs.

🗺️ 3GPP Knowledge Graph Interactive technical diagrams with zoom and pan, based on 3GPP standards: • LTE & 5G NR connected-mode mobility strategies (carrier layers, RSRP thresholds) • Signaling flow diagrams (RRC Connection Setup, NR Registration, VoLTE IMS) • RRC state machines and RACH procedures • LTE/NR frame structures (FDD/TDD, SSB, symbol mapping) • Logical, transport, and physical channel mapping (3G/4G/5G) • Idle-mode procedures and cell selection/reselection flows

🔢 RF Technical Calculators Field-ready calculation tools: • FSPL — Free Space Path Loss • Link Budget (MAPL) • EARFCN ↔ Frequency (LTE) • NR-ARFCN ↔ Frequency (5G NR) • RSRP to RSSI converter • LTE Theoretical Throughput • EIRP and more

🔧 Guided Troubleshooting Problem-resolution scenarios with root causes, step-by-step diagnostics, and solutions for the most common RAN issues: coverage gaps, throughput degradation, interference, handover failures, VoLTE, and Carrier Aggregation.

🏭 Vendor Information Technical profiles for the main RAN vendors: Ericsson, Huawei, Nokia, Samsung, and ZTE — including software versions, key features, and implementation differences.

🔍 Smart Global Search Instantly find any parameter, KPI, troubleshooting scenario, or diagram with full-text search and filters by technology (3G/4G/5G) and vendor.

📌 Notes, Favorites & Bookmarks Save important parameters, add your own field notes, and organize your favorite content for quick access.
