This protocol has a problem called hidden terminal problem ¨
¨
. It occurs when
a device is so far from another one that they are not able to sense each other
producing a collision if both transmit at the same time. For avoiding this problem
there is the RTS/CTS Exchange where the device, before transmitting, requests
for the medium (RTS) and if it receives an acknowledge called CTS, then it can
proceed to transmit avoiding collisions.
