Before You Begin

Before installing and setting up the CMAP, Ruckus Wireless recommends that you first
complete the following pre-installation tasks.

Prepare the Required Hardware and Tools

You must supply the following tools and equipment:
A notebook computer running Windows 7/Vista/XP with one wireless 802.11b/g/n
■
network card and one Ethernet card installed
Coaxial cable with a male F connector (connected to the CMTS backbone)
■
If you plan to use DC to power the CMAP (for staging or debugging purposes only),
■
you will need a DC power supply (see DC Power Supply in
NOTE: At the beginning of each procedure, this guide lists the specific tools, accessories,
and equipment that you will need to complete the procedure.

Perform a Site Survey

Before installing the CMAP, perform a site survey to determine the optimal access point
placement for maximum range, coverage, and network performance. When performing a
site survey, consider the following factors:
Data rates: Range is generally inversely proportional to data rates. The maximum radio
■
range is achieved at the lowest workable data rate. Higher data rates will generally be
achieved at closer distances.
Physical environment: Clear or open areas provide better radio range than crowded
■
or filled areas. The less cluttered the operating environment, the greater the wireless
range.
Obstructions, building materials, and sources of interference: Physical obstructions,
■
such as concrete pillars, steel beams, filing cabinets, buildings, or trees, can block or
hinder wireless communication. Avoid installing the CMAP in an environment where
there is an obstruction between sending and receiving devices. A number of machines
and electronic devices that emit radio waves – wireless phones, microwave ovens,
satellite dishes – interfere with and block wireless signals. Building materials used in
construction also influence radio signal penetration. For example, drywall construction
permits greater range than concrete blocks.
Mounting: The CMAP is designed to hang on a 1/4 to 3/8" support wire. The hangers
■
will allow a 2" bundle of cables between the support wire and the CMAP.
