Features:

1.Power and receiving sensitivity  Transmission power: 5W, RX current: <45mA, TX current:1.5A. High receiving sensitivity: -123dbm.2. Modulation mode and Frequency  Modulation mode: GFSK, Frequency :430MHz---470MHz.3. High anti- interference and low BER(Bit error Rate) Based on the GFSK modulation mode, the high- efficiency forward error correction channel encoding technology is used to enhance datas resistance to both burst interference and random interference and the actual bit error rate of 10-5 ~ 10-6 can be achieved when channel bit error rate is 10-2.4. Long transmission distance  Within the range of visibility, It can transmit >20km when the antenna height is grater than 8m(), and>10km()5. Transparent data transmission  Transparent data interface is offered to suit any standard or nonstandard user protocol. Any false data generated in the air can be filtrated automatically (What has been received is exactly what has been transmitted). 6. Multi- channel The standard JZ878 configuration provides 16 channels to meet the multiple communication combination mode of the user.7. High speed wireless communication and Large data buffer zone   When the RF baudrate is quicker than COM baudrate, allowing to transmit unlimited length data at one time, when the speed rate is slower or equal the interfaces, allowing the transmission of 255 Bytes long data frames at one time for more flexible programming by users. 8. Intelligent data control and the user doesnt need to prepare excessive programs  Even for semi duplex communication, the user doesnt need to prepare excessive programs, only receiving/transmitting the data from the interface. JZ878 will complete the other operations automatically, such as transmission/receiving conversion in the air, control, etc.9. High reliability, small and light  Single chip radio - frequency integrated circuit and single chip MCU are used for lessened peripheral circuits, high reliability, and low failure rate. 10. Watchdog monitor  Watchdog monitors the inner function, it changes the traditional product structure and also improve the reliability of our modules.
