Tab 1: Device Information

This tab displays static technical specifications of your device's operating system, hardware, and cellular modem.

Section A: System Information

Core operating system and processor details.

---

Section B: Modem Information

Cellular modem hardware and firmware specifications.

---

Tab 2: Resource Utilization

This tab is your device health dashboard, showing performance metrics and 24-hour historical trends.

Metrics Cards

Three cards display current resource usage across critical components.

CPU Utilization

Displays:

• Number of CPU cores

• Current utilization percentage

Example:

CPU: 1 cores

Utilization: 45%

---

RAM Utilization

Displays:

• Total RAM capacity

• Currently used RAM

• Utilization percentage

Example:

RAM: 128 MB total

Used: 66 MB (51.5%)

💡 Memory Management: High RAM usage isn't always problematic. Modern systems use available RAM efficiently. Concern arises when usage stays at 90%+ for extended periods.

---

Storage Utilization

Displays:

• Total storage capacity

• Used storage space

• Utilization percentage

Example:

Storage: 512 MB total

Used: 270 MB (52.73%)

Common Storage Consumers:

• Logs

• Application data

---

24-Hour Performance Graphs

Below the real-time cards, three line graphs display historical resource usage trends.

Graph Specifications:

• Time Range: Last 24 hours

• Data Points: Every 1 minute

• X-Axis: Time (hours)

• Y-Axis: Utilization percentage (0-100%)

Graph Types:

1. CPU Usage Graph (Green line)

2. RAM Usage Graph (Blue line)

3. Storage Usage Graph (Yellow line)

---

Analyzing Performance Trends

Normal Patterns:

CPU:

• Fluctuates based on workload

• Spikes during data transmission or processing

• Should return to baseline after tasks complete

RAM:

• Typically steady with gradual increases

• May step up when new processes start

• Rarely decreases significantly without restart

Storage:

• Gradually increases over time

• Sudden jumps indicate large file writes

• Decreases indicate log rotation or cleanup

Tab 3: Network Information

This tab provides detailed connectivity information for both wired (Ethernet) and wireless (Cellular) network interfaces.

The tab is organized into two sections:

1. Ethernet Card Information

2. Cellular Card Information

---

Section A: Ethernet Card Information

Wired network interface details for WAN (internet) and LAN (local network) connections.

Typical Display: Multiple ethernet interfaces may be shown (e.g., WAN, LAN, LAN2)

Ethernet Parameters

---

Section B: Cellular Card Information

Wireless cellular network connectivity details for mobile or backup internet connections.

Cellular Parameters

---

Interpreting Signal Strength

Signal strength is measured in dBm (decibel-milliwatts), a logarithmic scale where higher (less negative) values indicate stronger signals.

Signal Quality Scale:

Factors Affecting Signal:

• Distance from cell tower

• Physical obstructions (buildings, terrain)

• Weather conditions

• Network congestion

• Antenna quality and positioning

---

Cellular Troubleshooting Quick Guide

Problem: Poor Signal Strength (<-100 dBm)

Solutions:

1. Antenna Positioning: Relocate device or adjust external antenna

2. Alternative Location: Move device to higher elevation or near window

Problem: No Cellular Connection

Check:

• ✅ SIM card inserted correctly

• ✅ Carrier account is active and paid

• ✅ APN settings match carrier requirements

• ✅ Device is in carrier coverage area

• ✅ IMEI is not blocked by carrier

Problem: High Data Usage

Investigate:

• Check Downloaded/Uploaded Data totals

• Review application data transmission settings

• Confirm data is being sent via cellular (not ethernet)

• Look for unauthorized usage or malware

Tab 4: GPS Location

This tab manages device location tracking through automatic GPS data or manual coordinate entry.

Location Tracking Modes

The tab offers two mutually exclusive modes:

1. Auto Mode: Automatic GPS tracking

2. Manual Mode: User-defined coordinates

---

Option A: Auto Mode

Automatic location tracking using the device's internal GPS modem.

How It Works:

1. Device's cellular modem contains GPS receiver

2. Modem locks onto GPS satellites (requires 4+ satellites)

3. Location data calculated on device

4. Coordinates transmitted to Atra RMS

5. Map updates automatically

---

GPS Data Fields

When Auto mode is active and GPS has a fix, the following data is displayed:

---

Understanding GPS Accuracy

Satellites Count:

• 4+ satellites: Minimum for 3D fix (lat, lon, altitude)

• 3 satellites: 2D fix only (lat, lon, no altitude)

• 8-12 satellites: Optimal accuracy

• <3 satellites: No position fix possible

HDOP (Horizontal Dilution of Precision):

• Quality Indicator: Lower values = better accuracy

• Scale:

• 1.0-2.0: Excellent (typical accuracy: 1-3 meters)

• 2.0-5.0: Good (typical accuracy: 3-10 meters)

• 5.0-10.0: Moderate (typical accuracy: 10-30 meters)

• >10.0: Poor (accuracy degraded)

Validity Codes:

• 'A' (Active/Valid): GPS data is current and reliable

• 'V' (Void/Invalid): GPS data is stale or unreliable

---

GPS Troubleshooting

Problem: No GPS Fix

Common Causes:

• ❌ Device is indoors (GPS requires clear sky view)

• ❌ Device is in metal enclosure (blocks signals)

• ❌ GPS antenna not connected properly

• ❌ Location service disabled in device settings

Solutions:

1. Move Device: Place near window or outdoors temporarily

2. Check Antenna: Verify external GPS antenna connection

3. Wait: First fix can take 5-15 minutes ("cold start")

4. Verify Settings: Ensure GPS service is enabled

Problem: Poor Accuracy (High HDOP)

Solutions:

• Improve Sky View: Remove obstructions above device

• Wait: Accuracy improves as more satellites are acquired

• External Antenna: Use high-quality external GPS antenna

• Check Environment: Avoid placement near RF interference sources

---

Use Cases for Auto GPS Mode

Ideal Scenarios:

• ✅ Vehicle-mounted devices (fleet tracking)

• ✅ Mobile equipment monitoring

• ✅ Temporary installations requiring location verification

• ✅ Asset tracking applications

• ✅ Devices requiring location-based automation

Not Recommended:

• ❌ Stationary indoor installations

• ❌ Underground or heavily shielded locations

• ❌ Locations with poor GPS visibility

---

Option B: Manual Mode

User-defined static location coordinates.

How It Works:

1. User enters Latitude and Longitude manually

2. Coordinates stored in cloud only

3. Location displayed on Overview map

4. No data transmitted from device

---

Manual Location Entry

Input Fields:

Latitude:

• Format: Decimal degrees

• Range: -90° to +90°

• North: Positive values

• South: Negative values

• Example: 23.0225 (23° N)

Longitude:

• Format: Decimal degrees

• Range: -180° to +180°

• East: Positive values

• West: Negative values

• Example: 72.5714 (72° E)

---

Finding Coordinates for Manual Entry

Method 1: Google Maps

1. Open Google Maps (maps.google.com)

2. Right-click on desired location

3. Click "What's here?"

4. Coordinates appear at bottom (click to copy)

5. Format: Latitude, Longitude (e.g., 23.0225, 72.5714)

Method 2: GPS Device/Phone

1. Use smartphone GPS app

2. Stand at device location

3. Record coordinates from app

4. Enter into Manual Location fields

Method 3: Physical Address Lookup

1. Use geocoding service (e.g., geocode.xyz)

2. Enter physical address

3. Service returns coordinates

4. Verify accuracy on map before using

---

Important Limitations of Manual Mode

⚠️ Critical Understanding:

Manual location data is stored ONLY in the cloud, NOT on the physical device.

Implications:

• Map Display: Device appears at manual location on Overview map

• Device Reality: Physical device has no knowledge of this location

• Mismatch Possible: Device may be physically elsewhere

⚠️ Use Manual Mode Only When:

• GPS is unavailable (indoor, underground, shielded locations)

• Device is stationary and location won't change

• Approximate location is sufficient for your needs

• You understand the location is for reference only

---

Use Cases for Manual Mode

Appropriate Scenarios:

• ✅ Fixed indoor installations (factories, server rooms)

• ✅ Underground installations (basements, tunnels)

• ✅ Devices in GPS-shielded enclosures

• ✅ Legacy devices without GPS capability

• ✅ Approximate location sufficient for inventory purposes

Not Recommended:

• ❌ Mobile devices requiring real-time tracking

• ❌ Situations requiring precise location verification

• ❌ Applications with location-based automation

• ❌ Compliance scenarios requiring actual device location
