Students should write programs and prepare lab sheet for most of the units in the syllabus. Majorly, students should practice design and implementation of wireless network. Students are advised to implement the modulator de-modulator, frequency planning, channel assignment as well as routing algorithms used in wireless network. Students are advised to use simulators. Students are advised to visit the mobile service operators, network service providers, internet service providers and prepare the report including architecture, service, and functioning of the wireless network.
