Abstract: A grid gateway and a transmission tower management system having a plurality of the grid gateways are disclosed. The grid gateways are connected with one another to form a mesh network. A plurality of sensors are provided within a wireless transmission range of the grid gateways. The sensors collect and send environmental parameters to the corresponding grid gateway within the wireless transmission range, in order to choose an optimal transmission path in the mesh network through grid gateways to transmit. The environmental parameters are transmitted through the optimal transmission path to a server for storage and analysis. A grid gateway and a transmission tower management system having a plurality of the grid gateways have broad and local area wireless transmission ability, so as to overcome restrictions of topography and communication to execute broad area management and monitor tasks.
