At present, many high-end restaurants have implemented computer management and ordering systems, and the usual ordering system is to place a wired touch screen ordering terminal on each floor or in a large area. The waiter still records the menu on paper and then inputs the dish name that the customer has ordered on the terminal. Although this is much more advanced than traditional all paper menu ordering, the efficiency is still not high because the waiter still needs to manually record the ordering content and input it into the terminal.

Due to the small data traffic of the ordering system, but the large number of rooms and areas, a AP with a relatively large coverage area is required to meet the requirements.

For smaller restaurants, one AP can fully cover them. For environments that cannot be covered by a single device, it is necessary to add several devices according to the environment. APs have WDS function, and multiple devices can be wirelessly connected to each other to achieve a larger coverage area
