Wireless Concentrator

Overview：

The main function of the wireless concentrator is to effectively transmit data and send command on the basis of 470-520MHz radio frequency module and wireless AdHoc network. Wireless concentrator is developed by adopting high performance Arm hardware platform combined with current wireless communication technology.

Functional Characteristics：

1. It adopts master-slave reading mode and wireless meter realizes automatic networking from top to bottom, and optimizes routing by utilizing receiving-sending electric field intensity. It is a wireless meter that uses network ID to distinguish different networks in the same area.

2. It adopts high performance ferroelectric memory, data can be saved for more than 2 years, and erasing life can reach more than three million times.

3. RS232 interface is offered to facilitate connection of handheld meter reader to wireless concentrator and to realize on-site data reading of wireless meter. Operating frequency: 470 MHz.
