The power of each base station s transmitting in the MHz band and situated in i any geographic location otherr than that described above is limited to an EIRP of 1640 W/MHz, when transmitting with an emission bandwidth greater than 1 MHz. A licensee operating a base station in n the MHz band utilizing a power greater than 1640 watts/mhz EIRP must coordinate such operations in advance with all parties addressed in the rules. In measuring transmissions in this band using an average power technique, the peak-to-average ratio (PAR) of the transmission may not exceed 13 db. RSS : There is no power limit specified for base station equipment inn the RSS-139. EIRP compliance is addressed at the time of licensing, as required by the responsible IC I Bureau. Licensee s are required to take into account the antenna gain to get the maximum usable power settings to prevent the radiated output power to exceed the ERP/EIRP limits specified in SRSP-513 When the transmitter power is measured in terms of average value, the peak-to-average ratio of the power shalll not exceedd 13 db.

The specified measurement bandwidth for out of band emission measurement is 1 MHz. However, In the 1 MHz band immediately outside and adjacent to the band edges, the unwanted emission power may be measured with a resolution bandwidth of at least 1% of the emission bandwidth. A narrower resolution bandwidth is allowed to be used, providedd that the measured power is integrated over thee full required measurement bandwidth of 1 MHz or 1% of the emission bandwidth, as applicable. Where a smaller RBW was usedd the limit in the plot is adjusted by 10 log (RBW used /RBW s specified) [db]. A resolution bandwidth of 200 khz was used 1 MHz to 6 MHz away fromm the band edges, to compensate for the reduced measurement bandwidth the limit was adjusted by 7 db to -20 dbm (10 log (200 khz/ 1 MHz)). In the 1 MHz band immediately outside and adjacent to the band edges a resolution bandwidth of 20 khz was used. To compensate for the reduced measurement bandwidth the limit was adjusted by 3.67 db to dbm (10 log (20 khz/ 46.5 khz)). Before comparing the results to the limit, 6 db [10 log (4)] should be added according to method 2 measure and add 10 log(nn ANT ) of FCCC KDB D01 Multiple Transmitter Output v01r02 Note: In this case this is a very conservativee approach as the same carrier frequency can only be allocated to two ports at a time. The remaining ports must be allocated a to different frequency.
