Wireless communication technical indicators
Rate: 2Mbps, because the air transmission time is very short, the collision phenomenon in wireless transmission is greatly reduced.
Multi-frequency point: 125 frequency points, meeting the needs of multi-point communication and frequency hopping communication
Ultra-small: built-in 2.4GHz antenna, small size, 15x29mm
Low power consumption: When operating in the answer mode , fast air transmission and start up time greatly reduce current consumption
