Cor all of the following problems, assume the following conditions. - Transmit over an 802.11 n physical link at 600Mbps. - Only a single source is transmitting and never encounters a busy medium, so never uses exponential backoff. - This singlesource is backlogged, so it always has a packet to send. - SIFS = 16 microseconds, PIFS = 25 microseconds, and DIFS = 34 microseconds - Acknowledgement packets have no data in the frame body. - Propagation delay is negligible enough to be ignored. - Ignore physical layer headers. - Use the frame format that only uses the fields that are always present, so 14 octets. Next we wish to use group acknowledgements to achieve over 1000Mbps, still also using this infinite PHY transmissidn speed. Use a data packet of size 2,775 octets with all other parameters the same as Question 2. What is the minimum number of packets in a group to achieve this? Assume the RTS/CTS mechanism is used
