Description

Technical Field

A wireless pager is a wireless electronic device that usually consists of a transmitter and a receiver. It is widely used in various places, including restaurants, entertainment venues, factories, supermarkets, offices, and homes.

[0003] For example, CN221043129U discloses a wireless voice pager, including a main unit and multiple extension units. Each extension unit includes: a low-power extension control module, an extension wireless module, a voice module, an extension power module, a switch detection module, and a wake-up module. The extension power module includes a first power port and a second power port. The first power port supplies power to the extension control module and the extension wireless module.
