Regulatory planning

Regulatory planning
This section describes how to plan PTP 250 links to conform to the regulatory restrictions
that apply in the country of operation.
It is the responsibility of the user to ensure that the PTP product is operated in accordance
with local regulatory limits.
Contact the applicable radio regulator to find out whether or not registration of the
PTP 250 link is required.

Regulatory limits

The local regulator may restrict frequency usage and channel width, and may limit the
amount of conducted or radiated transmitter power.
regulatory limits that apply in typical countries of operation.
Many countries impose EIRP limits (Allowed EIRP) on products operating in the 5.4 GHz
and 5.8 GHz bands. These limits are calculated as follows:
•
In the 5.4 GHz band (5470 MHz to 5725 MHz), the EIRP must not exceed the lesser of
30 dBm or (17 + 10 x Log Channel width in MHz) dBm.
•
In the 5.8 GHz band (5725 MHz to 5875 MHz), the EIRP must not exceed the lesser of
36 dBm or (23 + 10 x Log Channel width in MHz) dBm.
Some countries (for example the USA) impose conducted power limits on products
operating in the 5.8 GHz band.
