UNIK4750/Lecture notes

(back to UNIK4750) What have you learned today?

Examples?

% How can we evaluate?

= L4 - Smart Grid and AMS =
 * examples of adequate security
 * (how long validity of crypto...)
 * challenge of time synchronisation
 * traditional security testing mechanisms is valid, e.g....

Smart Meter
 * integrity protection

= Example from UNIK4700 - Radio Propagation model = What will we learn today
 * Modes of Propagation
 * Free Space Propagation
 * Transmit Power
 * EIRP
 * Permittivity
 * Permeability
 * Attenuation
 * Reflection, Scattering, Diffraction

Test yourself, answer these questions

 * Convert to dB, dBm: Pr = Pt . Gt . Gr . L(free)
 * What is the exact difference between permeability and permittivity?
 * What is Relative permittivity? and Relative Permeability?
 * Define Propagation constant
