    摘要: Provided are a method of controlling frame transmission in a wireless local area network (WLAN) and an apparatus using the same. A first retransmission control method includes: comparing the number of errors in a frame received from a server with a predetermined threshold; and adaptively not allowing retransmission of the frame on the basis of the comparison result. Therefore, optimal pictures can be provided without regard to a state of a WLAN environment by adaptively allowing retransmission frames in which errors are detected.
