A3-7 O-to-I penetration loss model for model B Standard Indoor loss: Path loss through external wall: [dB] deviation: σP [dB] [dB] Low-loss model 0.5d2D-in 4.4 High-loss model 0.5d2D-in 6.5 Note 1: For model B, is minimum of two independently generated uniformly distributed d2D-in variables between 0 and 25 m for UMa_B and UMi_B, and between 0 and 10 m for RMa_B. shall be d2D-in UT-specifically generated. Both low-loss and high-loss models are applicable to UMa_x and UMi_x. Only the low-loss model is applicable to RMa_x. The composition of low and high loss is a simulation parameter that should be determined by the user of the channel models, and is dependent on the use of metal-coated glass in buildings and the deployment scenarios. Such use is expected to differ in different markets and regions of the world and also may increase over years to new regulations and energy saving initiatives. Furthermore, the use of such high-loss glass currently appears to be more predominant in commercial buildings than in residential buildings in some regions of the world. 3.3 Car penetration loss The pathloss incorporating O-to-I car penetration loss is modelled as in the following: (3-4) PL = PLb + N(μ, σP2) where is the basic outdoor path loss given in section 3.1. = 9, and = 5. Optionally, for PLb μ σP metallized car windows, = 20 can be used. The O-to-I car penetration loss models are applicable μ for at least 0.6-60 GHz. 3.4 LOS probability The LOS probabilities are in Table A3-8. A3-8 LOS probability Channel LOS probability InH_x UMa_x Outdoor users: Indoor users: Use in the formula above instead of d2D-out d2D
