Low Power Radio Long Range Wireless RF Module For Automatic System
Troubles: Short Distance
Cause and Remedy:
* Environment very bad or the antenna is blocked
* Power match or not. Voltage and current is large enough
* The existence of the same frequency or magnetic or electrical interference, or replacement of the
channel away from sources of interference
Troubles: Between devices not communicated
Cause and Remedy:
* Without power
* Module has destroyed
* Frequency inconsistency
* The pin of sleep mode not set
* Communication at both ends of the air rate, parity inconsistency
If the actual error rate 10-4, users need to send 1KB about 10000bit information, if the 1KB data as a
packet, sent at least theoretically, there will be a data error in the receiver, then the 1KB data can never
be received correctly. If it is divided into 10 packages, each package 100B, then send 10 packets, the
packets according to a probability of only 1 error, the error in the form of a packet retransmission by
ARQ 1, although it took more than 1 packet and the efficiency decreased by about 10%, but it can
guarantee all the information is correctly received.
