Labrotary Work
labwork
1.
Students should write programs and prepare lab sheets for most units in the syllabus. They are advised to practice designing and implementing wireless network systems as well as implementing modulator/demodulator frequency planning channel assignments along with routing algorithms used in wireless networks simulation tools.
2.
Students are encouraged to visit mobile service operators or network service providers to prepare reports on the architecture, service delivery mechanisms, and functioning of wireless networks.
