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 >800 m with AT-4 antenna’s height greater than 1m (BER=10-3@433MHz,1200bps). Within the range of visibility, the reliable transmission distance is >800 m with AT-4 antenna’s height greater than 1m (BER=10-3@470MHz,1200bps). Within the range of visibility, the reliable transmission distance is >400 m with AT-4 antenna’s height greater than 1m (BER=10-3@868MHz,1200bps). Within the range of visibility, the reliable transmission distance is >300 m with AT-4 antenna’s height greater than 1m (BER=10-3@915MHz,1200bps). 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 SRWF-1021 configuration provides 8 channels. If users need, it can be extended to 16/32 channels in the multiple communication mode. 7. Dual serial port, 3 interface modes SRWF-1021 provides 2 serial ports and 3 interfaces, with COM1 as the TTL level UART interface and COM2 as user defined standard RS-232/RS-485 interface (user only needs to plug/pull 1 bit short circuiter and energize it to make the definition).19200 baud rate only has TTL level UART interface. 8. Large data buffer zone
Interface baud rate is 1200/2400/4800/9600/19200bps with format of 8N1/8O1/8E1/9N1 and user self-definition, allowing the transmission of long data frames at one time for more flexible programming by users. (If users need, it can also transmit the data in unlimited

length at one time). 9. Intelligent data control and the user doesn’t need to prepare excessive programs Even for semi duplex communication, users don’t need to prepare excessive programs, only receiving/transmitting the data from the interface. SRWF-1021 will automatically complete other functions, such as transmission/receiving conversion in the air, control, etc. 10. Low power consumption and sleeping function
+5V supply power, receiving current is 28±2mA, transmitting current is 38±2mA, and sleep current is 5±2uA. 11. High reliability, small and light Radio frequency integrated circuit and MCU are used for lessened peripheral circuits, high reliability, and low false bit rate.
