Interference between LMS and FS at 300GHz

Desired-to-undesired ratio (D/U) defined by the ratio of the short distance LMS signal power and the FS signal power, detected by an LMS receiver, as a function of a beam direction difference.

Carrier frequency: 300GHz (both for LMS and FS)

Antenna gain: 50dBi (FS), 30dBi (LMS)

Transmission power: 20dBm (FS), 10dBm(LMS)

Distance: 300m (FS), 1m(LMS)
