(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
