Matching of antenna in measurement & UMs
Measurements performed with specific antennas
Effect of RX antenna taken out
TX antenna remains directional (no AoD)
In most cases, antennas used in measurement DO NOT match those in UMs!
We have all (for UM1 & UM5)!

Pointing the antenna
If we are to define “golden set of channel impulse responses”, how do we point the antenna pattern?
Especially in NLOS situations
For LOS we assume perfect aiming
For NLOS
Strongest path 1
Highest total power 23
