NH-1110N is a wireless module used to network dispersedly. It works in the band of 433MHz (other bands is defined by users), the standard maximum output power is 100mW (20dBm), the maximum transmitting current is less 80mA, receiving current is 18mA, when working voltage is 3.3V to 3.5V; RF modulation is GFSK, UART baud is from 2400~115200; The networking protocols have embedded in the module so that it is easy to use the module when users explore them without any modification of protocols and data structure.
MESH is a distributed symmetrical network, adopts private route protocols to use the redundancy in the Internet. Self-healing network, stability and perfect data throughput capacity make it excellent. No need time to network when the power on. 255 level routes and 10 million nodes support the huge scale network. There are many advanced wireless techniques like wireless frequency hopping, auto-adapt rate, reliable wireless wakeup technique in all networks (non-forward and single tone), interlaced correct code and so on in physical level, while the smart collision-avoiding arithmetic in link level improves the capacity of interfere.
