Off-Grid Wi-Fi Mesh Systems

To transmit information from a source to a destination without interruption from electromagnetic interference, a strong wireless network connection is required. These wireless networks may be powered by direct current from a battery or a direct source. The challenge arises when a wireless network is installed at a remote location. In this paper, an off-grid energy Wi-Fi mesh system for remote areas is proposed. The system is self-powered, and to ensure 24 hours energy production, a hybrid solution of vertical wind turbine and the solar cell is used. Dedicated routers are designed using Raspberry Pi, and other supporting electronic circuitry and results are analyzed. To avoid bandwidth issues, the network offloading concept is exploited using a novel concept of power used by each node. The proposed system is portable and suitable for remote areas where grid-connected energy availability is an issue.
