FCC Base Station and device power settings
Part 96.41(b) of the FCC rules states:
...
1Category B CBSDs will only be authorized for use after an ESC is approved and commercially deployed consistent with §§96.15 and 96.67.
§96.43 Additional requirements for category A CBSDs.
(a) Category A CBSDs shall not be deployed or operated outdoors with antennas exceeding 6 meters height above average terrain. CBSDs deployed or operated outdoors with antennas exceeding 6 meters height above average terrain will be classified as, and subject to, the operational requirements of Category B CBSDs.
...
(c) Any CBSD operated at higher power than specified for Category A CBSDs in §96.41 will be classified as, and subject to, the operational requirements of a Category B CBSD.
§96.45 Additional requirements for category B CBSDs.
(a) Category B CBSDs must be professionally installed.
...
(d) When registering with an SAS, Category B CBSDs must transmit all information required under §96.39 plus the following additional information: antenna gain, beamwidth, azimuth, downtilt angle, and antenna height above ground level.
The following information has been taken from FCC, https://www.fcc.gov/35-ghz-band-overview#:~:text=In%202015%2C%20the%20Commission%20adopted,federal%20use%20of%20the%20band. ….
n48 5G Signal Pro Settings
Follow the steps as specified in 5G Project Setup using the following project template:
...
Configure the cells as per other technologies in sectors dialog. Note the maximum EIRP for n48 sectors is 47 dBm per 10 MHz. So for 20 MHz the EIRP shall not exceed 50 dBm. See FCC part 96 for more information.
Configure the receiver. Note the UE power cannot exceed 23 dBm for mobile UE’s. See FCC part 96 for more information.
...
All other standard Signal Pro settings should apply.
B48 LTE 4G Signal Pro settings
LTE settings are similar to 5G settings. The same FCC power limits apply for LTE as they do for 5G.
Base Station EIRP shall not exceed 47 dBm/10 MHz. So for 20 MHz LTE, the maximum EIRP is 50 dBm. See figure 1 above.
UE’s are limited to 23 dBm. This limit is not based upon power spectral density. See figure 2 above. The mobile receiver noise bandwidths are defined as:
...
The system profile is set in Network Design/Analysis->LTE Networks->System details/Service area:
...
Set you system profile using the follow pull down depending on the spectrum allocation. TDD profiles are recommended as CBRS spectrum is unpaired.
...
TDD Configuration 1 (DSUUDDSUUD) and configuration 2 (DSUDDDSUDD) are more commonly used depending upon traffic asymmetry.
...
An LTE Band 48 template can be downloaded and placed into into C:\ProgramData\EDX\Templates and unzip.
