2. Our Ethernet connection uses Manchester encoding: 0 1 1 0 0 0 1 0 2 Manchester encoding -2V Suppose our Ethernet runs at 100Mbps speed, calculate the number of symbols transmitted per second. (1 points) 3. One of our wifi network standards is IEEE 802.11ac. It can run at 6.77 Gbit/s data rate. Calculate the symbol rate for 801.11ac at 6.77 Gbit/s data rate. (suppose it uses 256-QAM 8 bits per symbol). (1 points) 4. If you had to download a 100 MBytes video (1Byte = 8bits) from a website, approximately how long would it take to transfer it over the following connections? (2 points) a. ADSL at 1Mbps b. Cable modem at 15Mbps c. Fiber optical modem at 50Mbps d. AT&T mobile data speed at 10Mbps 2.
