This assignment solution covers a range of topics in wireless networks and communication. It begins by converting binary data into analog waveforms using modulation techniques like ASK, FSK, PSK, and QAM. It then computes frequency assignments for different data combinations, explores analog and frequency modulation waveforms, and analyzes a 16 QAM constellation diagram. The solution also details the error detection process using Cyclic Redundancy Check (CRC) and calculates the frame check sequence. Furthermore, it computes the transmitted signal using Direct Sequence Spread Spectrum (DSSS), differentiates between infrastructure and ad hoc modes in WLAN, and compares TCP and OSI protocols for wired and wireless LANs. Finally, it explains the advantages of hexagonal cells in cellular communications and provides a comprehensive understanding of the subject matter.
