7.6 Designing for a Neutral Host System
Designing the LGCell for a neutral host system uses the same design rules previously
discussed. Since a neutral host system typically uses multiple systems in parallel, we
find it best to design for the worst case system so that there will not be holes in the
covered area and the economies of a single installation can be achieved. For example,
as indicated Section 7.1, the 1900 MHz RF signals do not propagate throughout a
building as well as the 800 MHz systems, therefore, we design to the 1900 MHz path
loss formula.
7.6.1 Capacity of the LGCell Neutral Host System
As indicated in Section 2.3, “System Bandwidths,” on page 2-10, each Main Hub can
support more than one sub-band of the Cellular or PCS bands. The exception to this is
the iDEN Main Hub, because the SMR band is not split into sub-bands.
The 800 MHz Main Hub can support both the A band and the B band simultaneously.
Also, the 1800 MHz and 1900 MHz Main Hubs can support two bands each (as the
frequencies currently are allocated).
For example, a neutral host system that consists of one iDEN, one 800 MHz, and two
1900 MHz systems can support up to seven separate service providers:
•1 on iDEN
• 2 on 800 MHz, A band and B band
• 2 in each 1900 MHz
