Suppose your notebook is connecting to the Internet by WiFi using 802.11b (11 Mb/s). Suppose your notebook and the AP are using the RTS/CTS sequence to reserve the channel. If your notebook wants to transmit 1400 bytes of data, and all other stations are idle at this time. Given that the size of the frames that carry RTS, CTS, and ACK is 34 bytes, and the waiting times of SIFS and DIFS are 10s and 50s respectively. Assuming no bit errors and ignoring propagation delay, calculate the time required to transmit the frame and receive the acknowledgment.
