1. a. A WLAN uses the 1-Mbps IEEE 802.11 infrared standard and the 16-PPM modulation scheme. Compute the period of transmission (time between bits). b. What is the average time between pulses (1 values) and the corresponding average rate of pulse transmission? c. Compute the minimum time between adjacent pulses d. Compute the maximum time between adjacent pulses. 2. For IEEE 802.11a standard, describe how the modulation technique and coding rate determine the data rate. 3. a. List at least four network devices required to implement a WLAN. b. Describe the role each device plays in the implementation of the WLAN. c. Describe how an ad-hoc LAN is different from an infrastructure WLAN.
