Favorite wireless Ethernet/IP Solution

Need to do wireless communication between 2 shuttle cars and a master PLC. It is my first time doing wireless communications between PLCs. What’s everyone’s recommended solution?

Each shuttle car will have a local 1769-L18 doing control, but they will prod/cons a few tags to a 1769-L36. All logic and navigation will be done local on the car. The prod/cons tags will only communicate target destination position, so 100-250ms lag isn’t an issue...
