Installation Instruction

Installation Guidelines

Systems must be professionally installed by a qualified engineer familiar with WLAN, including trained

partners and resellers.

Because the access point is a radio device, it is susceptible to common causes of interference that

can reduce throughput and range. Follow these basic guidelines to ensure the best possible

performance:

• Perform a site survey before beginning the installation.

• Install the access point in an area where structures, trees, or hills do not obstruct radio signals

to and from the access point.

• The access points can be installed at any height, but best throughput is achieved when all the

access points are mounted at the same height. We recommends installing the access points no

higher than 40 feet to allow support for wireless clients on the ground.

Site Surveys

Every network application is a unique installation. Before installing multiple access points, 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 conditions 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.

Before Beginning the Installation Before you begin the installation process: • Ensure that a site survey has been performed. • Ensure that your network infrastructure devices are operational and properly configured. • Ensure that your controllers are connected to switch trunk ports. • Ensure that your switch is configured with untagged access ports for connecting your access points.
