I have conceptual misunderstandings in wireless communication. We use
bit error rates in wireless communication in NS. I do not understand
what packet loss and bit error rate mean. When we are using 802.11
wireless interfaces in an ad-hoc network and between any two hops, a
forwarded frame is CRC checked, WHAT DOES BIT ERROR
What I mean is that how can a frame get to a receiver with loss, I
think it either completely does or doesn't get there. There's no way to
get to the receiver with loss. Am I right or wrong?
By the same reasoning, what does a packet loss mean? Doesn't 802.11 use
ACKs? If it does it continually send a frame until it gets to the
receiver, so where's the loss?
I appreciate any answer,
