This assignment provides solutions to problems related to wireless network communication. It covers the conversion of binary data into analog waveforms using various modulation techniques such as Amplitude Shift Keying, Frequency Shift Keying, and Phase Shift Keying. It also includes calculations for frequency assignments, drawing analog modulation and frequency modulation waveforms, and illustrating the 16 QAM constellation diagram. Furthermore, the assignment explains and demonstrates the error detection process using Cyclic Redundancy Check (CRC), computes frame check sequences, and calculates transmitted signals using Direct Sequence Spread Spectrum. Finally, it differentiates between Infrastructure and ad hoc modes in WLAN, compares TCP and OSI protocols, and explains why hexagonal shape cells are preferred over square and circle shapes for cellular communications. The document is available on Desklib, a platform offering study tools and resources for students.
