Hello,
I am running coverage simulations in WinProp / ProMan for a master's
thesis on multi-band cellular planning. My current scenario includes
three bands working correctly: LTE B8 (950 MHz), LTE B1 (2160 MHz),
and NR n77 (3525 MHz).
I now want to add a fourth band at 7 GHz, corresponding to the
IMT-2030 candidate range identified by WRC-23 (Resolution 256,
7125–8400 MHz) and currently under study in 3GPP Rel-19
("Channel Model Validation of TR 38.901 for 7–24 GHz"). This is
sometimes referred to as FR3 or the "centimeter-wave / Golden Band".
When I try to configure a transmitter at 7000 MHz, ProMan returns
the following error, even in a brand-new empty project containing
a single transmitter at 7 GHz (no other carriers loaded):
"Two different frequency ranges are defined for 5G networks:
- FR 1: Carrier frequencies between 450 MHz and 6 GHz
- FR 2: Carrier frequencies between 24.25 GHz and 52.6 GHz
You cannot use carrier frequencies of FR 1 and FR 2 in one project.
Please make two different projects."
It appears the software classifies any frequency above 6 GHz as FR2
and additionally validates it against the 24.25–52.6 GHz range,
which 7 GHz fails.
My questions:
- Is there an official way to simulate carriers in the 7–15 GHz range
in the current WinProp release? Is FR3 / centimeter-wave support
on the roadmap? - Is there a configuration workaround (e.g., declaring the air
interface as generic OFDM rather than 5G_TDD, or disabling the
FR1/FR2 validation) that allows propagation simulations at 7 GHz
while reusing the 3GPP TR 38.901 channel model, which is formally
valid 0.5–100 GHz?
Thank you in advance for any guidance.
