Description:
1.Power and receiving sensitivity
Transmission power:5W/10w,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 interfer ence 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 tran smitted).
6. Multi- channel
The standard JZX878 configuration provides 16 channels to meet the multiple communication
combination mode of
