This document provides a comprehensive solution to a wireless network assignment, covering various aspects of wireless communication and networking. The assignment includes the conversion of binary data into analog waveforms using different modulation techniques such as Amplitude Shift Keying, Frequency Shift Keying, and Phase Shift Keying, along with Differential Phase Shift Keying, and multilevel variations of ASK and PSK. It also involves computing frequency assignments for different data combinations, drawing analog and frequency modulation waveforms, and constructing a 16 QAM constellation diagram. Furthermore, the assignment requires an explanation and diagram of the Cyclic Redundancy Check (CRC) error detection process, computation of the frame check sequence, and computation of the transmitted signal using Direct Sequence Spread Spectrum. The solution also addresses the differences between infrastructure and ad hoc modes in WLAN, along with their respective diagrams, and compares the differences between TCP and OSI protocols for wired and wireless LANs using diagrams. Finally, the assignment concludes with an explanation of why hexagonal cells are preferred over square and circle-shaped cells in cellular communications, supported by relevant references.
