1 PRODUCT DESCRIPTION
This section describes the Digivance Neutral Host (NXD) Radio Access Node (RAN).
1.1 General Description
The RAN, shown in Figure 1, is the remote component in the Digivance NXD Multi-Band
Distributed Antenna System. The RAN is a pole-mounted or pad-mounted, weather-resistent
cabinet, housing electronic modules that operate on an internal cPCI backplane. Included are a
central processing unit, a system interface, an optical interface, optical to RF data converters,
RF multicouplers, and DC power supplies. The RAN also houses rectifiers, backup batteries,
power amplifiers, and optical wave division multiplexers. Optical and RF functions are both
required because the RAN exchanges data with the system Hub using an optical link and
exchanges data with wireless users using RF signals. Each RAN provides the system with an RF
antenna and can accommodate up to four bands (
PCS A-F, SMR A, Cell A”/A, or Cell B/B’). Dual
RANs installed at the same location can accommodate up to eight bands using a common
antenna.
