I3 (Indoor 3) Scenario

I3 scenario

  • An indoor conference room scenario
  • A 10 m x 11 m x 3 m conference room with its hallways
  • Two access points inside the conference room at 2 m height
  • More than 118 thousand candidate users in LOS and NLOS conditions
  • Datasets are available at operating frequencies 2.4 GHz and 60 GHz

Key components

  • Two access points or base stations (BSs): BS1 and BS2
  • Each antenna array element at each BS is an isotropic antenna
  • The BSs are mounted on 2 m height on opposing walls
  • 9.67 m separation between the BSs
  • BS1 is on the right side of the room in Figure 1
  • BS2 is on the left side of the room in Figure 1
  • Two uniform x-y user grids (UGs): UG1 and UG2
  • Total number of users = 118,959 users
  • The first user in every user grid is always the user with the lowest (x,y) coordinate
  • Each antenna array element at each user is an isotropic antenna
  • First user grid (UG1)
    • Named “LOS user grid”
    • Located between the two tables with a length of 5.5 m and width of 1.2 m
    • The height of this user grid is 60 cm
    • Accessed from Row 1 to Row 551 (551 rows in total)
    • 121 users per row (121 users with the same y coordinate)
    • 1 cm spacing between adjacent users
    • Number of users in UG1 = 66,671 users
  • Second user grid (UG2)
    • Named “NLOS user grid”
    • Located outside the conference room with a length of 8.5 m and a width of 1.2 m
    • The height of this user grid is 1 m
    • Accessed from Row 552 to Row 1159 (608 rows in total)
    • 86 users per row (86 users with the same y coordinate)
    • 1.4 cm spacing between adjacent users
    • Number of users in UG2 = 52,288 users
  • The room dimensions are 10 m x 11 m x 3 m
  • The 8 human models are 1.8 m in height
  • Each one of the two conference tables is 5.6 m in length and 1.4 m in width
  • The southern door opening in Figure 1 is 3 m in width
  • The Northeastern door opening in Figure 1 is 2 m in width
  • As for the propagation model, each channel path can undergo a maximum of 2 reflections and 1 transmission before reaching the receiver.
