Page 46: Radar Avoidance
Wireless operation Chapter 1: Product description Radar avoidance In regions where protection of radars is part of the local regulations, the PTP 250 must detect interference from radar-like systems and avoid co-channel operation with these systems. The requirements for a master device are: The device can only transmit on available channels, of which there are none at initial power up.
Page 47: Country Of Operation
PTP 250 User Guide Wireless operation The requirements for a slave device are: The slave device can only transmit after receiving a transmission from its associated master to demonstrate that the channel is an available channel. The slave device is required to vacate the channel when the master device has detected a radar signal.
Page 48: Using Frequency Planning
Wireless operation Chapter 1: Product description Using frequency planning Networks will benefit from the use of fixed channel allocations if (a) the network consists of multiple PTP links, and (b) RF interference predominantly arises from equipment in the same network. Frequency planning is the exercise of assigning operating channels to PTP units so as to minimize RF interference between links.

The following topics are described in this chapter: Regulatory planning on page describes how to plan PTP 250 links to conform to the regulatory restrictions that apply in the country of operation.
Page 60: Regulatory Planning
Once the correct Country Code is set by the user on first login, the PTP 250 caculates these limits automatically. Many countries impose EIRP limits (Allowed EIRP) on products operating in the 5.4 GHz and 5.8 GHz bands.
Page 61: Conforming To The Limits
In Canada, NO operation is permitted in the band 5600 – 5650 MHz. Conforming to the limits When a new PTP 250 unit is first accessed via the web interface, the user is required to select the Country Code from a list. Generally, the PTP 250 firmware does not allow the unit to be configured to operate outside the regulatory limits that apply to the selected country.
Page 62: Radar Detection
For example, at 5.8 GHz in the UK and some other European countries, the RTTT band 5795 MHz to 5815 MHz is barred. With the appropriate configuration for a country in this region, the PTP 250 will not operate on channels within this band.
