</td></tr></tbody></table>

</div>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 (&lt;-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.

[![image.png](https://docs.atreyo.in/uploads/images/gallery/2026-04/scaled-1680-/UGuimage.png)](https://docs.atreyo.in/uploads/images/gallery/2026-04/UGuimage.png)

#### 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.

[![image.png](https://docs.atreyo.in/uploads/images/gallery/2026-04/scaled-1680-/ibGimage.png)](https://docs.atreyo.in/uploads/images/gallery/2026-04/ibGimage.png)

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

</td></tr></tbody></table>

</div>---

##### 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
- &lt;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)
- &gt;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.

[![image.png](https://docs.atreyo.in/uploads/images/gallery/2026-04/scaled-1680-/40Mimage.png)](https://docs.atreyo.in/uploads/images/gallery/2026-04/40Mimage.png)

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

[![image.png](https://docs.atreyo.in/uploads/images/gallery/2026-04/scaled-1680-/Gjnimage.png)](https://docs.atreyo.in/uploads/images/gallery/2026-04/Gjnimage.png)

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

---
