Introduction• Penetration Loss should be considered on almost all the
simulation scenarios presented in [1]– For residential scenario, wall/floor penetration happens– For Enterprise Scenario, cubic wall penetration happens– For outdoor scenario, building/house wall penetration happens
• Penetration loss is different for different materials and for different frequencies

Outdoor-to-Indoor and indoor-to-outdoor Penetration Loss
• Measurements and Information:• In [2], it is shown that the measured penetration loss are
– Brick exterior wall: 14.5dB
• In [3], LTE-advanced simulation setup uses fixed penetration the loss as 20dB
• In ITU [4], Baseline evaluation configuration parameter for Macro suburban uses the fixed penetration loss as 20dB
• In [7], 20dB at 5GHz exterior wall/floor penetration loss is suggested.

Indoor Wall Penetration Loss
• Indoor walls– For residential indoor wall penetration– For Enterprise cubic wall penetration
• Our measurements at 2.4GHz

• In US, sheertrock/wood frame wall are generally used in famly houses.
• In EU and China, Brick wall is more popular.

Indoor Wall Penetration Loss (cont’s)
• Base on our measurements, we saw averagely <5dB indoor wall penetration loss.– We did not count the path loss in our measurement.
• In [2], the measured penetration loss of interior wall is 4.7dB
• In [5], for different walls, it is between 3 to 6dB.• Other literatures show that 5GHz has <0.5dB more
penetration loss than 2.4GHz.

Floor Penetration Loss
• In [6], a floor penetration loss is measured in 1.8GHz and shows that roughly 18dB for the first floor.
• We probably need find more measurements to finalize the floor penetration loss.

How to Model the Penetration Loss?
• ITU channel model the penetration by a random variable with a std– Walls/floor are built with different materials and with different
thickness.
• Other simulation setups use fixed parameters for penetration loss– Maybe simpler for network simulations
• More discussion probably is required.
