This document presents a detailed solution to a wireless network and communication assignment. The solution covers various modulation techniques (ASK, FSK, PSK, DPSK, QAM), frequency assignments, and waveform diagrams. It includes calculations for frequency assignments based on given parameters. The assignment also addresses error detection using Cyclic Redundancy Check (CRC), frame check sequence computation, and the application of Direct Sequence Spread Spectrum (DSSS). It further explores the differences between infrastructure and ad hoc modes in WLAN, comparing TCP and OSI protocols for wired and wireless LANs, and explaining the advantages of hexagonal cells in cellular communication. References are provided at the end.
