5 Physical Installation
Prepare the Required Hardware and Tools
You must supply the following tools and equipment:
■ A notebook computer running Windows XP/2000 and installed with one wireless
802.11b/g/n network card and one Ethernet card
■ 6mm flathead screwdriver
■ 6mm Phillips screwdriver
■ 10mm ratchet wrench
■ 3mm Phillips screwdriver (if you will be using DC power)
■ Electric drill with 8mm drill bit (if mounting on a flat surface)
Perform a Site Survey
Before installing the Wireless Bridge, perform a site survey to determine the optimal
Wireless Bridge placement or 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.
■ Line of sight: Bridging two networks together with Ruckus Wireless Bridges requires
direct line of sight between the two bridges for best results. Physical obstructions, such
as concrete pillars, steel beams, trees or other buildings can block or hinder wireless
communication. Wherever possible, ensure that there is direct line of sight between
the two Wireless Bridges and that obstructions are unlikely to break line of sight.
■ Antenna configuration: Proper antenna configuration is a critical factor in maximizing
radio range. As a general rule, radio range is increased by mounting the radio higher
off of the ground (for recommended orientation examples, refer to Figure 15
on
page 25).
■ Physical environment: Clear or open areas provide better radio range than closed or
filled areas. The less cluttered the operating environment, the greater the wireless
range.
■ Signal interference: A number of machines and electronic devices that emit radio waves
– cranes, 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.
