Determine the in-building environment: Refer to Section 5.4, “Estimating RF
Coverage,” on page 5-13.
• Determine which areas of the building require coverage (entire building, public
areas, parking levels, and so on.)
• Obtain floor plans to determine floor space of building and the wall layout of
the proposed areas to be covered. Floor plans are also useful when you are
selecting antenna locations.
• If possible, determine the building’s construction materials (sheetrock, metal,
concrete, and so on.)
• Determine the type of environment:
– Open layout (for example, a convention center)
– Dense, close walls (for example, a hospital)
– Mixed use (for example, an office building with hard wall offices and cubi-
cles)

Determine the appropriate estimated path loss slope that corresponds to the
type of building and its layout, and estimate the coverage distance for each
RAU: Refer to Section 5.4, “Estimating RF Coverage,” on page 5-13.
Use the path loss slope (PLS), which gives a value to the RF propagation charac-
teristics within the building, to convert the RF link budget into an estimate of the
coverage distance per antenna. This helps establish the quantities of Fusion Sin-
gleStar equipment you need. The actual path loss slope that corresponds to the
specific RF environment inside the building can also be determined empirically
by performing an RF site-survey of the building. This involves transmitting a cal-
ibrated tone for a fixed antenna and making measurements with a mobile antenna
throughout the area surrounding the transmitter.

Determine the items required to connect to the base station: Refer to
Section 5.6, “Connecting a Hub to a Base Station,” on page 5-23.
Once you know the quantities of Fusion SingleStar equipment to be used, you can
determine the accessories (combiners/dividers, surge suppressors, repeaters,
attenuators, circulators, and so on.) required to connect the system to the base sta-
tion.
The individual elements that must be considered in designing a Fusion SingleStar
solution are explained in the following sections.
