> It fundamentally assumes a perfect channel, which is why wireless connectivity doesn't play well with it Wireless generally handles the retransmissions on a lower layer (802.11 and cellular data connections both do it), so TCP doesn't see lost packets. (Of coursee with bad wireless connections you get complete cut outs completely so that even link layer retransmissions won't work) If there was a lot of room for improvement in TCP here, other protocols would have done them and probably modern TCP would have incorporated them in turn.
