Best Practices for

Installation and Setup

of Crestron RF Products

Introduction

This document outlines the Crestron

recommended practices for installing and

troubleshooting Crestron RF devices. Explanations of Crestron RF protocols and

correct installation procedures are provided.

Unlike Cresnet

or Ethernet networks that use a physical medium of transmission,

ensuring connectivity and eliminating interference in a wireless network is much

more difficult. Wireless networks require a significant amount of planning compared

to hard-wired networks. Many additional factors affecting the strength and reliability

of RF signals must be taken into consideration, including walls, furniture, other

electronic equipment, and even people.

Many common household electronic devices emit electromagnetic energy, which can

severely degrade wireless network performance. It is therefore necessary to use

special test equipment to detect the level and locations of interference present in each

unique installation. The most common cause of interference problems is a direct

result of installing equipment that operates on the same frequency as a cordless

phone, baby monitor, or microwave oven. This document helps avoid those

problems.

Wireless Characteristics

Wireless signals are transmitted and received using waves in the radio frequency

(RF) spectrum, which is a portion of the electromagnetic spectrum. The long radio

wavelengths allow signals to pass through solid objects such as walls. The limited

range of wireless signals in the RF spectrum allows networks in different buildings

on the same street to coexist. The following illustration shows the RF spectrum

within the electromagnetic spectrum.
