8 Excess loss [db] Foliage Loss : Average of [10], [11] and [13] Foliage depth [m] frequency (GHz)

9 Pure foliage penetration loss Excess loss considering reflection and diffraction path need between Tx and Rx RX TX View of RX RX 2.65 m 2.3 m TX 3 m m 2 m 2 m 2 m TX RX 1.15 m Pure foliage-penetrated path can be severely attenuated, as 7~10 [db/m] The long-distance between Tx/Rx and tree can help other propagation pathway

10 Power-Angular Spectrum Analysis on Foliage Loss - Full-scanning on foliage-penetration path over azimuth / elevation angles - Single-tree (depth 4.1m) and double-tree (depth 7.8) foliage penetration measurement TX 4.1 m RX TX (Azi, Ele) = (5, 10) PL = 94.2 db (Azi, Ele) = (30, 5) PL = db (Azi, Ele) = (-5, 20) PL = db Single-Tree Foliage Loss TX view (Azi, Ele) = (0, -5) PL = 95.5 db (Azi, Ele) = (-15, 5) PL = 96.5 db 7.8 m RX (Azi, Ele) = (15, -25) PL = db (Azi, Ele) = (-5, -10) PL = 96.6 db TX RX RX 2 nd tree Double-Tree Foliage Loss Power-Angular Spectrum (PAS) of Single-Tree Foliage Loss

11 6.3 and 6.5 db/m penetration loss was observed respectively for single tree and double tree (Azi, Ele) = (0, 5) db Excess Loss 10.5 (4.1m) Received PAS after single-tree penetration 4.1m FSPL PAS (Azi, Ele) = (5, 5) db Excess Loss 17.9 (7.8m) Received PAS after double-tree penetration 7.8m FSPL PAS

12 Reflection path is one of major components of received signals Tx Wall Reflection Loss 56.9 db Penetration Loss 46.8 db Ground Reflection Loss 49.3 db

13 Foliage loss is increasing along foliage depth, but not linearly RX RX 2m TX TX 330m 6m TX Main propagation mechanisms on foliage are 1) surface-wave propagation over tree-top/bottom 2) forward-scattering within vegetation 3) ground-reflected path on tree-trunk Tx Rx

14 Foliage loss is not extremely increased - Foliage loss measurement at 20 GHz [1] - Tendency matches with previous results - 30~35 db excess loss up to 50m depth Tx-Tree distance, 125m Foliage Loss Measurement at 20 GHz in [1] Tx-Tree distance, 11m Distance between Tree and Transmitter - Long distance is likely to have other propagation pathway - Short distance may block reflected pathways - Dual-gradient model Foliage Loss Measurement at 28 GHz in Daejeon, Korea Long Tx-Tree distance Short Tx-Tree distance
