System Planning 17
System Planning
This chapter describes the site planning of an ePMP link.
The following topics are described in this chapter:
l
Factors to be considered when planning the proposed network is described under Site planning.
Site planning
Conduct a site survey to ensure that the proposed sites meet the requirements defined in this section.
Site installation
An ePMP site typically consists of a high supporting structure such as a mast, tower, or building for the
devices.
Find a location for the device that meets the following requirements:
l
The equipment is high enough to achieve the best radio path.
l
People can be kept a safe distance away from the equipment when it is radiating. .
l
The equipment is lower than the top of the supporting structure (tower, mast, or building) or its
lightning air terminal.
l
There is one Ethernet interface, a copper Cat5e connection from the device to the power supply,
and network terminating equipment.
Grounding and lightning protection
Structures, equipment, and people must be protected against power surges (typically caused by
lightning) by conducting the surge current to the ground through a separate preferential solid path. The
actual degree of protection required depends on local conditions and applicable local regulations. To
adequately protect an ePMP installation, both ground bonding and transient voltage surge suppression
are required.
Warning
Electro-magnetic discharge (lightning) damage is not covered under warranty.
The recommendations in this guide, when followed correctly, give the user the
best protection from the harmful effects of EMD. However, 100 percent
protection is neither implied nor possible.
Details of lightning protection methods and requirements can be found in the international standards IEC
61024-1 and IEC 61312-1, the U.S. National Electric Code ANSI/NFPA No. 70-1984, or section 54 of the
Canadian Electric Code.
Note
International and national standards take precedence over the requirements in this guide.
