    Application Details

    The process took a dayinterviewed at Qualcomm in January 2012.

    Interview Details

    Some basic probability/stochastic process questions about lossy wireless channels.

    The last question the interview asked was: "Suppose we make 10 packet transmissions per second over a wireless channel, the channel is lossy such that with probability 1/10 a packet transmission will fail. The transmitter knows perfectly whether a transmission succeeds or fails. When it fails, the transmitter retransmit the packet, until it finally succeeds. So what is the throughput we can get?"

    This was a VERY VERY simple question that the throughput should be 9 packets/second! The interview didn't agree and simply emphasized "because of retransmission, throughput should be reduced more than 1/10" repeatedly.

    Couldn't achieve a consensus with him after a long debate and that's it.

    Interview Questions
    • Given a wireless channel with loss rate 0.1, what's the throughput one can get with retransmission.   View Answers (6)
