Large-number data transmission In theory, when the interface data rate is faster than the RF data rate, KYL-200L transceivers can sent unlimited-long data package, but long packages more than 120B are not recommended. The length of each package should be between 60~100B. We also recommend our users to use Automatic Error Request Equipment (ARQ) to prevent wrong information. Reasons: What if the actual transmission BER (Bit Error Rate) is 10-4, 1 packet with 1KB data which is about 10-thousand bits, is sent, theoretically, at least 1 bit will be received wrongly, then the 1KB information will never be received correctly. But if we package the data into 10 packets with 100B for each, when all 10 packets are sent, there will be only 1 packet wrong according to this probability. After that, resend this wrong packet using ARQ mode. So by resending one more packet and the efficiency rate is reduced 10%, all data will be absolutely received correctly. 10. Antenna configuration: Many appropriative antennas for low power RF modules are selected to meet different users’ antenna configurations. Please ask our Sales for more information about the antenna’s dimension and performance. a. Helical SMA antennas KYL-ANT-433-10-SMA: 100mm helical SMA antennas with high gain and low cost, reach a long distance. KYL-ANT-433-3-SMA: 28mm SMA helical antenna with magnetic core, small size, beautiful appearance (like the mobile phone antenna) KYL-ANT-433-10-ZSMA: 100mm SMA helical antenna with folding joint, easy for adjusting the direction and fixing. |
