Cisco IR500 Series WPAN Gateway and Range Extender Installation and Configuration Guide
Chapter 2 Installation
Installation Guidelines
- Rear: 1.0 in. (25.4 mm)
- Top: 1.0 in. (25.4 mm)—the device can be installed in a 1.25
” tall slot, but the mounting surface must
have thermal conductive properties equivalent to or better then 302 stainless steel (16.3 W/m-k)
Contact your Cisco Technical Assistance Centre (TAC) if tighter spacings are required.
Site Surveys
Every network application is a unique installation. Before installing multiple WPAN gateways and
WPAN range extenders, you should perform a site survey to determine the optimum use of networking
components and to maximize range, coverage, and network performance.
Consider the following operating and environmental con
ditio
ns when performing a site survey:
• Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio
range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the
radio data increases.
• Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio
range. As a general rule, range increases in proportion to antenna height. However, do not place the
antenna higher than necessary, because the extra height also increases potential interference from
other unlicensed radio systems and decreases the wireless coverage from the ground.
• Physical environment—Clear or open areas provide better radio range than closed or filled areas.
• Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of
wireless devices. Avoid locating the devices in a location where there is an obstruction between the
sending and receiving antennas.

WPAN Gateway Installation Options and Components
The WPAN gateway has a ruggedized IP41 enclosure and it can be installed in the following locations:
• Outdoor cabinet installations—the WPAN gateway is mounted on a DIN rail within the cabinet. For
more information, see the “Mounting the WPAN Gateway on a DIN Rail” section on page 2-9.
• Interior wall installations—the WPAN gateway is mounted on a wall using wall mounting brackets.
For more information, see the “Mounting the WPAN Gateway on a Wall” section on page 2-13.
WPAN Range Extender Installation Options and Components
The WPAN range extender (basic or advanced model) is mounted on a pole. For more information, see
the “Mounting the Range Extender on a Pole” section on page 2-15.
