- Ultra low power data transmission.
 - visual distance transmission distance up to 875mtr.
 - based on FSK/GFSK way of debugging, efficient communication protocols, good reliability, low bit error rate.
 - data transparent transmission, transmission is longer than the data frame.
 - colleagues provide RS – 232 / RS – 485 / TTL level interface, optional I/O port.
 - can be used to point to point, point to many, many to point communication mix a variety of ways.
 - only data control, users need extra program.
 - carrier frequency 433 MHZ, also can provide 315/868/915 MHZ carrier frequency.
 - watchdog fact monitoring, an external antenna is optional
