WIFI and Internet Connectivity

Introduction

This guide assists Lynx-HCF software users in understanding the roles and differences between Wi-Fi (LAN) and Internet (WAN) connectivity in mobile health clinics, whether vehicle-based or fixed units.

• LAN (Local Area Network): Connects devices within a limited area, typically via Ethernet or Wi-Fi.
• WAN (Wide Area Network): Connects devices across multiple locations globally.

Wi-Fi connectivity is crucial for on-site operations and screening functions, while Internet connectivity is essential for creating patient records and syncing data to the cloud.

Wi-Fi Connectivity (LAN)

Importance

• Data Transfer: Enables data transfer between tablets and modality worklist for X-ray participant details.
• Backup Logs: Facilitates backup logs on the modality computer.
• Screening Process: Required for all screening processes, even without internet connection.

Ensuring Wi-Fi Connection

1. Keep Tablets in Range: Ensure tablets are within Wi-Fi range and connected to the correct local API. A red banner indicates no connection.
2. Troubleshooting:
   • Check if the Wi-Fi router is powered on and functioning (signal lights visible).
   • Contact HCF support if issues persist.

Wi-Fi Range Notification

• A red banner warns if a tablet is not connected to the correct Wi-Fi, out of range, or if the router is off.

Data Management

• Tablets Only: Participant details should be captured or modified only on tablets. Direct participants to the data capturer for corrections.

Internet Connectivity (WAN)

Importance

• Electronic Medical Records (EMR): Creates participant/patient cloud EMRs.
• Data Sync: Syncs participant details, X-rays, and results to the cloud for case management and reporting.

Internet Connectivity Tiers

1. Daily Monitoring:

   • Check "Outstanding Sync" on tablets.
   • Monitor Qure "Pendings" and Orca "Not Found" in the Lynx-HCF Client Management List.
   • Run ORCA Sync on startup and ensure "JdicomCC - Status" is error-free.

2. Level 1 - Little Action Needed:

   • Discuss dual SIM options with HCF support.
   • Leave the modality computer on for automatic connectivity.

3. Level 2 - Monitoring Required:

   • Consider satellite service options with HCF support.
   • For fixed units, transfer data manually from a stable internet access point.
   • For mobile units, drive to an area with stable internet for syncing.

4. Level 3 - Intervention:

   • Follow Level 2 actions if data is not syncing.

Data Quality and Participant Information

• Modality Restrictions: Do not capture or modify participant details on the modality to avoid mismatches.
• Tablet Management: Ensure all changes are made on tablets and referred back to data capturers if needed.
• Daily Monitoring: Regularly check "Outstanding Sync," Qure "Pendings," and Orca "Not Found" on tablets. Avoid clearing data or deleting the Lynx-HCF App without support instructions.
