The ZKManet2251UM is a 4W handheld mesh network device with a
transmission rate of up to 82 Mbps. It supports various
communication combinations, making it suitable for different
scenarios. It features a built-in display screen that can show
device status and connection status in real time. The device can be
worn by an individual, used in conjunction with a tripod relay, or
installed at fixed points. It can also be utilized on moving
vehicles, ships, robots, drones, and unmanned boats. With one-click
operation, it can be used anytime and anywhere without the need for
configuration or parameter changes.
