NOTE

 

Equipment supplied to the USA can ONLY be set to operate with a Country 
Code which is fully compatible with FCC Rules. 

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. Frequency planning must consider 
interference from any PTP unit to any other PTP unit in the network. Low levels of 
interference normally allow for stable operation and high link capacity. 

The frequency planning task is made more straightforward by use of the following 
techniques: 

x

Using several different channels 

x

Separating units located on the same mast 

x

Using high performance (directional) external antennas 

For help with planning networks, refer to 

Chapter 2 Planning considerations

, or 

contact a Motorola distributor or re-seller.
