An in-house ChromaWave Labs product — 8 months from concept to Play Store, built the same way we build for clients.

RF engineers and telecommunications specialists were juggling 5-7 separate apps during field visits — switching between calculators, reference sheets, and reporting tools, often in locations with poor connectivity where those apps failed exactly when they were needed most.

ChromaWave built GoodPAW: a single, unified mobile platform combining essential network diagnostics, RF analysis tools, and reporting capabilities in one field-ready application. Today it is used by 100+ RF professionals in the field, cutting tool-switching time by 68% and making site assessments 42% faster.

The Challenge

Network engineers and telecommunications specialists faced several critical challenges in their daily operations:

  • Engineers were using 5-7 separate applications during field visits, creating inefficiencies
  • Many critical calculations were being performed manually, introducing human error
  • Lack of standardized reporting tools led to inconsistent documentation across teams
  • Difficult access to reference data for region-specific frequency details and device credentials
  • Apps frequently failed in areas with poor connectivity, precisely when they were most needed

These challenges were resulting in longer site visits, inconsistent data collection, and potential errors in network planning and optimization. The consortium estimated that field engineers were spending up to 35% of their time managing tools and documentation rather than addressing actual network issues.

Our Solution

ChromaWave developed GoodPAW, a comprehensive mobile application designed specifically for network engineers and RF specialists, combining essential tools in an intuitive, field-ready interface.

Key Features

Network Dashboard

Real-time monitoring of network parameters and location information, providing engineers with instant access to critical connectivity data even in variable signal conditions.

RSRP Calculator

Advanced tool for calculating Reference Signal Received Power for LTE, NR1, and NR2 bands, essential for network planning and optimization with visual signal quality indicators.

RF Spot Check

Capability to import floor plans and conduct detailed RF spot checks, perfect for indoor coverage analysis and distributed antenna system (DAS) deployment planning.

Professional Reporting

Generation of detailed, professional reports from collected spot check data, ready to share with clients or team members in multiple formats (PDF, CSV, and native app format).

Technical Implementation

  • Cross-platform development using Flutter for both iOS and Android compatibility
  • Robust offline functionality using SQLite for local data storage and synchronization
  • AES-256 encryption for secure storage of sensitive device credentials
  • Tiered access model with freemium and subscription options using in-app purchases
  • Low-bandwidth API design for operation in poor connectivity conditions

The application was rigorously tested in actual field conditions with network engineers to ensure it met real-world requirements. Special attention was paid to battery optimization, as field engineers often work long hours without reliable access to charging facilities.

Senior RF Engineer, GlobalConnect Wireless

GoodPAW has completely transformed how our team conducts field assessments. Before this app, I was constantly switching between different tools and spreadsheets, often losing time and occasionally making errors in the process. Now, everything I need is in one place, and the offline capabilities mean I can work effectively even in areas with poor connectivity. The spot check feature with reporting has cut our documentation time in half. I honestly can't imagine going back to the old way of working.

What we'd do for you

If your team is fighting a version of this problem, this is exactly the kind of engagement we run. Most clients start with a fixed-fee audit or a 2–4 week sprint.
