Abstract
The present invention relates to a data collision prevention method that is capable of solving a so-called hidden channel problem that may arise when there are two wireless senders with different communication ranges. More particularly, the present invention relates to a data collision prevention method and a wireless sender enabling such prevention, wherein a data collision may occur when two wireless senders simultaneously transmit data to a receiver in a situation where only one wireless sender can detect a data transmission state of the other wireless sender.
