SignMetrix Impression Zone Calibration Capabilities

The platform combines centralized remote configuration, field-based calibration workflows, and Auto Calibration capabilities to help improve impression boundary accuracy across different store environments, fixture layouts, antenna placements, and RF conditions.

SignMetrix calibration capabilities are designed to support:

• Rapid deployment scalability
• Enterprise operational consistency
• Real-world environment validation
• Continuous measurement refinement
• Reduced operational overhead
• Improved impression accuracy across large fleets

The SignMetrix platform includes:

• Pre-Setup Manual Configuration
• Field Calibration via SignMetrix Field Services Mobile App

The Advanced Auto-Calibration Engine is available as an add-on package for customers requiring continuous optimization and adaptive refinement at scale.

Included Standard Calibration Capabilities

1. Pre-Setup Manual Configuration

The simplest deployment model allows impression zones to be remotely configured directly from the SignMetrix Dashboard.

Using the centralized management portal, admins can manually define:

• Impression zone radius
• Zone-level measurement parameters
• Device Group-level calibration settings

This methodology does not require on-site calibration and is commonly used for:

• Rapid deployments
• Standardized store layouts
• Controlled retail environments
• Enterprise rollout preparation

Benefits

• Fast deployment
• Remote configuration capability
• No field technician requirement
• Centralized fleet management
• Consistent deployment configuration across locations
• Reduced operational overhead by minimizing on-site deployment requirements

2. Field Calibration via SignMetrix Field Services App

The SignMetrix supports physical on-site calibration using the SignMetrix Field Services App.

This capability is commonly used for enterprise-scale retail media deployments where calibration accuracy, operational consistency, and environment-aware optimization are critical.

The platform enables field personnel to calibrate impression zones based on actual physical display positioning.

Field Calibration Capabilities

Field service personnel can:

• Verify player health and connectivity
• Validate BLE coverage behavior
• Perform physical impression boundary calibration
• Define impression zones using real-world RSSI measurements
• Validate antenna positioning and environmental conditions

Calibration Workflow

The workflow is intentionally simplified for operational scalability:

1. Open the SignMetrix Field Services App
2. Select the store and zone
3. Start the field calibration process
4. Position at the desired impression boundary
5. Wait 10 seconds countdown while the player measures RSSI and signal behavior
6. The platform establishes the initial impression coverage parameters for that zone

Benefits

• Environment-aware calibration
• Improved real-world accuracy
• Faster field deployment process
• Validation of physical RF conditions
• Supports enterprise-scale deployment standardization
• Reduces operational overhead by minimizing the need to dispatch field service personnel for recalibration activities

This methodology allows calibration settings to reflect:

• Actual store layouts
• Fixture positioning
• Antenna placement
• Environmental RF reflections
• Signal attenuation conditions

Add-On Package

3. Advanced Auto-Calibration Engine

The SignMetrix Advanced Auto-Calibration Engine is an optional enterprise add-on package designed for large-scale retail media deployments requiring continuous optimization and adaptive measurement refinement.

Unlike static calibration models, the auto-calibration engine continuously analyzes live operational data to improve impression boundary accuracy over time.

Auto-Calibration Analysis Inputs

The platform continuously evaluates:

• RSSI signal behavior
• Distance estimation patterns
• Dwell time consistency
• Signal density variations
• Repeat traffic behavior
• Historical zone interaction patterns
• Real-world shopper movement observations
• Long-term signal behavior trends

Using these inputs, the system continuously refines and optimizes the most probable impression zone boundaries for each environment.

Continuous Learning Model

Unlike manual calibration, auto-calibration is not fully instantaneous.

The model improves progressively as additional traffic and signal data are collected.

High-traffic locations may achieve strong calibration accuracy within approximately one week, while lower-traffic environments may require several weeks of operational data collection to fully optimize impression zone boundaries.

Recommended Deployment Model

Many enterprise customers use a hybrid deployment strategy:

• Initial manual or field calibration for baseline deployment
• Advanced auto-calibration for continuous optimization and refinement over time

Recommended Use Cases

The Advanced Auto-Calibration Package is commonly recommended for:

• Large retail media networks
• Enterprise-scale deployments
• High-density traffic environments
• Long-term audience measurement optimization
• Continuous operational improvement initiatives

Benefits

• Continuous adaptive optimization
• Reduced long-term manual calibration effort
• Improved measurement consistency
• Environment-aware learning models
• Scalable enterprise deployment support
• Ongoing refinement of impression boundary accuracy
• Reduced operational overhead through automated calibration refinement processes
