CROSS-REFERENCE TO RELATED APPLICATION

This application is based on and claims priority to Japanese Patent Application No. 2020-049424, filed on Mar. 19, 2020, the entire contents of which are incorporated herein by reference.

FIELD

Embodiments described herein relate generally to a wireless communication device and a wireless communication method.

BACKGROUND

In remote maintenance of point of sales (POS) products, a system is provided to perform long-distance wireless transmission of a user's product serial code to a maintenance center on a regular basis in order to track the location of a non-operating POS product which is in a packed state or a stopped state at night.

Because AC power supply cannot be used in a non-operational product, a wireless communication device attached to the non-operation product is powered by a battery. In this case, in order to reduce battery consumption, the wireless communication device starts up about once every few hours and wirelessly transmits a serial code of its own product.
