Site Planning A-1
Appendix A
Site Planning
This appendix provides information on site planning requirements for the installation of your
ZyAIR.
Introduction
The installation of a wireless network requires some additional planning over a wired network. This
planning includes RF (Radio Frequency) path planning, site preparation, and installation of outdoor
components such as outdoor units, antennas, lightning protection devices, and cabling suitable for outdoor
conditions. Furthermore, you also need to investigate the zoning laws as well as Federal Communications
Commission (FCC) and European Telecommunications Standards Institute (ETSI).
The technology implemented in this wireless bridge system can make use of multi-path signals, reducing
the effect of obstructions, however, it is important that the characteristics of the path be carefully examined.
With this knowledge, components and network requirements can be correctly planned for your specific
application.
This Appendix provides insight into the planning necessary to prepare your site for your outdoor wireless
bridge.
General Considerations
A basic consideration is the physical location of the sites at each end of the link. Because microwave
signals travel in a straight line, a clear line of sight between antennas is ideal. Frequently, however, the
locations of the desired links are fixed. When a clear line of sight cannot be achieved, you have to plan
accordingly.
Other general site considerations include:
 Is there a structure in-situ already on which you can mount the ZyAIR or would you be required to
construct one i.e. a mast for the sole purpose of mounting the ZyAIR?
 Would there be permit requirements for this?
 Possibility of future obstructions
 If trees grow too high will they interfere with the signal?
 Are there plans to erect buildings between the sites, which may inadvertently obstruct the
signal path?
