I was wondering if anyone out there could provide some clarification on the max EIRP limits for the Public Safety Licensed 4.9 GHz spectrum?
High power maximum conducted output power (dBm) = 33
(2) “High power devices are also limited to a peak power spectral density of 21 dBm per one MHz. High power devices using channel bandwidths other than those listed above are permitted; however, they are limited to peak power spectral density of 21 dBm/MHz. If transmitting antennas of directional gain greater than 9 dBi are used, both the maximum conducted output power and the peak power spectral densityshould be reduced by the amount in decibels that the directional gain of the antenna exceeds 9 dBi. However, high power point-to-point and point-to-multipoint operations (both fixed and temporary-fixed rapid deployment) may employ transmitting antennas with directional gain up to 26 dBi without any corresponding reduction in the maximum conducted output power or spectral density. Corresponding reduction in the maximum conducted output power and peakpower spectral density should be the amount in decibels that the directional gain of the antenna exceeds 26 dBi”.
Using a 20 MHz wide channel (max for this spectrum) it looks like from what I am reading you can go up to an EIRP of 59 dBm.
Any feedback on this would be greatly appreciated.
