Chapter 2 Preparing for Installation

Site Requirements

This section discusses the site requirements for both infrastructure and client devices.

For Infrastructure Devices

Because of differences in component configuration, placement, and physical environment, every
network application is a unique installation. Therefore, before you install any wireless infrastructure
devices (such as access points, bridges, and base stations, which connect your client adapters to a wired
LAN), a site survey must be performed to determine the optimum placement of these devices to
maximize range, coverage, and network performance. Appendix F, which is provided for people who are
responsible for conducting a site survey, explains how the site survey utility can be used to determine
the best placement for infrastructure devices within a wireless network.
Infrastructure devices are installed and initially configured prior to client devices.
Note

For Client Devices

Because the client adapter is a radio device, it is susceptible to RF obstructions and common sources of
interference that can reduce throughput and range. Follow these guidelines to ensure the best possible
performance:

Install the client adapter in an area where large steel structures such as shelving units, bookcases,
and filing cabinets will not obstruct radio signals to and from the client adapter.
Install the client adapter away from microwave ovens. Microwave ovens operate on the same
frequency as the client adapter and can cause signal interference.
