Field Work Area (FWA) site network topology integrating solar and battery power with MikroTik routing and Wi-Fi access via L2TP tunnels to HQ. Power flows from Solar Panels and Battery Bank through a Linovision POE-SW804 Switch, which supplies the MikroTik hEX 750 router and Wi-Fi Access Points. The MikroTik CHR at HQ establishes L2TP tunnels with the remote CPE Router and hEX 750, while the Wi-Fi Controller manages access points across the site. This architecture demonstrates resilient off-grid networking for remote field operations, combining renewable energy with carrier-grade routing and centralized management.
