1. Low power transmission With the transmission power of 17dBm. 2. ISM frequency band , requiring on application of frequency
point. Carrier frequency of 433MHz. 3. High anti- interference and low BER(Bit Error Rate) Based on the GFSK/FSK modulation mode, the high- efficiency forward
error correction channel encoding technology is used to enhance
data s 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, the reliable transmission distance
is 1200 m@ 1200 bps with AT-4 antenna s height greater than 1m . 5. Transparent data transmission Transparent data interface is offered to suit any standard or
nonstandard user protocol. Any false data generated in t |
