This document contains the agenda for a seminar on electromagnetic waves, antennas, wireless transmission parameters and calculations, narrowband transmission, data rates, and a wireless lab. The topics covered include Maxwell's equations, antenna types such as monopole, dipole and parabolic, the Marconi equation, RF power loss, EIRP, RSS, SNR, modulation techniques, wireless standards such as 802.11a/b/g/n/ac, and configuring devices in a wireless lab including access points, wireless routers, and security settings.
