Chapter 2 Installing the Access Point

Installation Guidelines

•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.

•Ensure that a DHCP server with Option 43 configured is reachable by your access points, or manually configure the controller information in the access point (for additional information, refer to the “Configuring DHCP Option 43” section on page F-1).

•Become familiar with the access point installation components (see the “Becoming Familiar with Access Point Installation Components” section on page 2-9).

Becoming Familiar with Access Point Installation Components

The access point is designed to be installed in an outdoor environment, such as the exterior roof overhang of a tall building or a streetlight pole. Carefully review the following figures to become familiar with the system components, connectors, indicators, cables, system interconnection, and grounding:

•Components in a typical access point installation (see Figure 2-1)

•Pole mount installation (see Figure 2-2)

•Cable strand mount installation (see Figure 2-3)

•Streetlight power tap installation (see Figure 2-4)

Note The illustrations in this document show all available connections for the access point. Unused connections are capped with a connector plug to ensure the watertight integrity of the access point, except for the AC power entry connector on the 1552E access point. Liquid-tight adapters are provided for connector openings, which can be installed before or after deploying the access point.

When not using the AC input connector to power the 1552E (for example when powering using the Cisco power injector), it is important to cover the AC power entry connector. The correct cap is Remke part number 75-0086 (http://www.remke.com/).
