The document outlines discussion topics for a week 4 activity on wireless communications, focusing on modeling the TCP/IP protocol against the OSI model and exploring wireless protocols like FDMA, TDMA, and CDMA. It includes prompts for responses about issues with existing satellite communication protocols and the prevalent network operating systems, emphasizing their differences in LAN and WAN contexts. Each response should be 200 to 300 words.
