Wireless Communication Assignment: Modulation, Protocols, and Networks

This document presents a comprehensive solution to a wireless communication assignment. It begins with calculations related to 4-ASK modulation, including frequency assignments for different data combinations. The solution then addresses questions on analog modulation waveforms, specifically focusing on frequency modulation. Further, the assignment includes the creation of a 16 QAM constellation diagram and explains the Cyclic Redundancy Check (CRC) error detection process. The solution also contrasts Infrastructure and Ad hoc modes in WLANs, along with their respective diagrams. A comparison of TCP and OSI protocols for wired and wireless LANs is also provided using diagrams, followed by an explanation of why hexagonal cells are preferred in cellular communications. The document includes references to relevant sources.
