Best Practices for
Installation and Setup
of Crestron RF Products
Introduction
This document outlines the Crestron
®
recommended practices for installing and
troubleshooting Crestron Radio Frequency (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 the user avoid those
problems.
Wireless Characteristics
Wireless signals are transmitted and received using waves in the 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.
