About this app

CellScout is a professional, enterprise-grade cellular drive-testing, network diagnostics, and cell mapping application designed for radio frequency (RF) engineers, telecom professionals, and network enthusiasts.

Tired of traditional network utility limitations that freeze during tower handovers, deplete your battery under intensive Dual-SIM workloads, or contaminate your coverage logs with "ghost sectors"? CellScout is built from the ground up to resolve these hardware-level challenges, delivering unmatched performance, safety, and data integrity.

UNCOMPROMISING DATA HYGIENE & MODEM PROTECTION
CellScout is powered by proprietary, low-level optimizations that resolve the limitations of traditional cellular telemetry tools:

• SMART HYBRID COOLDOWN™
Standard mapping utilities often freeze and drop telemetry packets during intense 5G SA/NSA handovers. CellScout’s real-time latency monitor detects RIL (Radio Interface Layer) lag instantly. During congestion, the app engages an adaptive, self-correcting cooldown, falling back to passive memory caches to guarantee 100% continuous data capture with zero dropouts.

• ECI BLEED & SECTOR RESOLUTION™
Android often reports stale cell identifiers during fast handovers, associating new physical signals with old logical tower IDs and corrupting maps. CellScout's active Identity-Physical Integrity Map tracks physical-to-logical pairings. If a contradiction is detected, it sanitizes the desynced metadata before committing, protecting your logs from ghost sectors.

• RIL HAMMER / MULTI-SIM PRESSURE MITIGATION
Dual-SIM devices can overload the physical modem during concurrent active telemetry scans, causing overheating, battery drain, and baseband locks. CellScout uses a thread-safe synchronization layer to serialize Multi-SIM queries. If a SIM experiences latency, other slots transition to passive read modes, reducing battery draw by up to 40%.

• HARDWARE PLL & CLOCK STEERING
At highway speeds, asynchronous GPS and cellular clocks cause spatial jitter and coordinate clumping. CellScout's software-based Phase-Locked Loop synchronizes snapshot schedules directly with physical GPS hardware coordinate arrivals, eliminating spatial drift and creating clean, mathematically precise drive-test routes.

PROFESSIONAL FIELD-TEST FEATURES
• Log & Map Real-Time Telemetry: Monitor 5G NR (Standalone & Non-Standalone), LTE, WCDMA/HSPA+, and GSM.
• Real-Time Band Information: Hardened PLMN-channel lookup database yields absolute band designations (e.g., n78, n258, b71, b41) automatically.
• Advanced Throughput & Latency Monitoring: Integrated passive and active background traffic speed testing, tracking jitter, packet loss, and ping latency without impacting battery.
• Master/Slave Remote Sync: Broadcast drive-test parameters, log filenames, and real-time GPS coordinates from a master device to multiple slave devices simultaneously—ideal for multi-operator mapping vehicles.
• External Hardware Compatibility: Compare internal phone GPS side-by-side with high-precision wired USB GPS receivers directly in the app.
• Highly Secure & Efficient: Outfitted with a secure, hardware-accelerated local encrypted database format with strict write-locks for industrial-grade data protection.

WHO IS CELLSCOUT FOR?
• RF Engineers & Network Planners performing signal drive tests, 5G SA rollout verifications, or neighbor cell analysis.
• Wireless Enthusiasts mapping local cell towers and seeking clean, error-free logs.
• Field Technicians identifying coverage gaps, cross-feeder issues, and co-channel interference.
