Operating Frequency Band 5150 – 5250 MHz
It is the responsibility of the installer to ensure that radios operating in the band 5150-5250
MHz are installed so that they do not exceed 21 dBm EIRP at any elevation angle above 30
degrees as measured from the horizon, as specified in FCC rule 47 CFR Part 15.407 (a)(1)(i).
This compliance can be achieved through proper selection of radio with antenna, angle of
elevation, and Tx power control to provide reasonable protection for co-channel
NGSO/MSS operations.
As shown in the typical deployment above, the highest antenna gain from the horizon
above 30 degree for antenna model 1 & 2 is below. For more detail information, please
refer to antenna specifications.
Antenna No Antenna Gain Antenna Install Degree
1 0.77dBi
Due to device restrictions installation position is as above picture, thus consider above 30
degrees highest antenna gain is chosen from E-Plane antenna specification of 30-150
degrees, for H- plane antenna gain will not affect above 30 degrees from the horizon,
therefore not required for evaluation.
2 -4.88dBi
Due to device restrictions installation position is as above picture, thus consider above 30
degrees highest antenna gain is chosen from E-Plane antenna specification of -60-60
degrees, for H-Plane antenna gain will not affect above 30 degrees from the horizon,
therefore not required for evaluation.
