I want to simulate a multi gNB multi UE scenario in n78 band (C bands 3.5 Ghz) which will be deployed in ASEAN region. How can I model various parameters like UE mobility, buildings, LOS/NLOS, gNB height, weather effects etc in NetSim?
Yes this should be possible. After you create the network topology, you can choose the operating band under Carrier configuration, Mobility is available under UE parameters, while LOS/NLOS options are available under gNB - chnanel characteristics
As Ashwini Bhat mentions n78 band can be directly selected in the NetSim gNB window.
For mutli UE and/or Multi UE, again just drag and drop the number of devices required.
Buildings can be also be configured in NetSim from the UI itself through the building icon in the menu. This is for indoor vs outdoor propagation and for outdoor to indoor RF losses.
The operating bands supported by NetSim 5G library is available in https://tetcos.com/5g.html. They include
* FR1 bands (Mid-band):
* n34 (2010 MHz – 2025 MHz), n38 (2570 MHz – 2620 MHz), n39 (1880 MHz – 1920 MHz), n40 (2300 MHz – 2400 MHz), n41 (2496 MHz – 2690 MHz), n50 (1432 MHz – 1517 MHz), n51 (1427 MHz – 1432 MHz),
* n77 (3300 MHz – 4200 MHz), n78 (3300 MHz – 3800 MHz), n79 (4400 MHz – 5000 MHz)
* FR2 bands (High band):
* n257 (26500 MHz – 29500 MHz), n258 (24250 MHz – 27500 MHz), n260 (37000 MHz – 40000 MHz), n261 (27500 MHz – 28350 MHz)

LOS/NLOS is a GUI setting which can vary from 100% LOS to 100% NLOS. There is also a statistical model of the standards implemented.
Placing the UE inside the building generates O2I (outdoor to indoor) losses and indoor propagation.
NLOS will lead to higher losses than LOS, and a UE inside a building will experience more loss than a UE outside.

Thank you all for your responses.
How can I find out the Max throughput vs. distance for LOS and NLOS conditions and for different TDD ratios?
You will need to run multiple simulations with combinations of a) UE at different distances from the gNB and b) UE states in LOS/NLOS. If you want maximum throughput then you should generate sufficient traffic (application) such that the gNB is under “saturation” or “full buffer” condition.
