Numbers of IBSs and the farthest distances to IBSs.
| | Antenna configuration | Number of visible IBSs*1 | Number of IBSs where received CCI level is greater than carrier sense level*2(%) | Farthest distances to IBSs (m) |
| | V | 38 (79.2%) | 38 (79.2%) | 6500 (9400) | | V_tilt | 32 (66.7%) | 27 (56.3%) | 6500 | | H | 23 (47.9%) | 17 (35.4%) | 2116 | | H_tilt | 11 (22.9%) | 6 (12.5%) | 1500 |
