the regulatory restrictions that apply in the country of operation.
•
Link planning on page 3-24 describes factors to be taken into account when planning links,
such as range, path loss and throughput.
•
Planning for connectorized units on page 3-29 describes factors to be taken into account
when planning to use connectorized ODUs with external antennas in PTP 670 links.
