Regulatory issues with connectorized units
Maximum EIRP for connectorized units
In most regions (including USA, Canada, Europe and Australia) operation of products
in the band 5470 MHz to 5725 MHz is constrained by an EIRP limit. The constraint is
that the EIRP must not exceed (17 + 10 x Log Bandwidth) dBm.
In some regions (including Europe) operation of products in the band 5725 MHz to
5850/5875 MHz is constrained by an EIRP limit. The constraint is that the EIRP must
not exceed (23 + 10 x Log Bandwidth) dBm.
As the PTP 54600 and PTP 58600 have an operating bandwidth from approximately 5
MHz to approximately 30 MHz, then the maximum allowed EIRP depends on the
operating bandwidth of the radio as shown in
Table 4-77
.

These EIRP limits apply in ETSI regions and FCC/IC regions at 5.4 GHz.
