2. Introduction
User’s Manual for ION
®
-U Page 15
2. Introduction
2.1. Purpose
Mobile telephone systems transmit signals in two directions between base
transceiver station (BTS) and mobile stations (MS) within the signal coverage area to
carry voice and data traffic.
If weak signal transmissions occur within the coverage area because of indoor
applications, topological conditions or distance from the transmitter, extension of the
transmission range can be achieved by means of an optical distributed antenna
system (DAS).
Office buildings, sports arenas, college campuses, industrial parks, and other areas
of high demand require the specialized capacity boost that an optical DAS can
provide to meet increasing customer demands for voice and data.
An optical DAS contains optical Master Units and a sufficient number of Remote
Units to provide the necessary coverage. The number of the Remote Units depends
on the coverage requirements of the DAS. The Remote Units are connected to the
Master Unit with optical links.
The Master Unit is the connection to the Base Transceiver Stations. The
configuration of a Master Unit depends on the number of the Remote Units and the
frequency range.
RF signals are transported to and from the Remote Units via optical fibers.
2.2. ION-U High Power Remote Units
The ION-U is an optical fiber based DAS system that efficiently takes the outputs of
multiple Base Transceiver Stations (BTS) sectors and converts those RF signals to
optical to send them over fiber optic cables to Remote Units to provide coverage in
indoor and outdoor locations. The system supports both low power and high power
remotes units and SISO and MIMO operation.
The ION-U H 7P/80-85P/17(E)P/19P is a multi-band, multi-operator Remote Unit
used in conjunction with a Master Unit in the ION optical distribution system. This
system transports up to five frequency bands simultaneously (700 MHz, 800/850
MHz, 1700/2100 MHz, and 1900 MHz), providing a cost-effective solution for
distributing capacity from one or more base stations.
It has been specifically tested and optimized for GMSK, EDGE, CDMA, UMTS,
HSPA+, LTE, and other OFDM modulations. Furthermore it is provisioned for future
modulation scheme evolutions.
These Remote Units feature independent downlink and uplink gain adjustments and
an integrated channel power detector for in-band spectrum and PIM analysis and
end-to-end auto leveling.

3. Functional Description
Page 16 User’s Manual for ION
®
-U
The unit utilizes a single fiber to support multiple bands in both the uplink and
downlink directions. WDM (Wave Division Multiplex) filters are integrated in the
optical modules. For the UL, a wavelength within 1546 nm – 1550 nm is used. For
the DL, a wavelength of 1310 ±10 nm is used. The maximum optical output power for
the UL and DL is 6.7 mW.

figure 3-1 ION-U High Power RU block diagram
In the Downlink (DL) path, the Remote Unit provides:
Optical to RF conversion of the input optical signal
Automatic Gain Control (AGC) of each converted signal to compensate for
optical losses
RF amplification of the converted RF signal for transmission while maintaining
an excellent signal-to-noise ratio
RF filtering to reject spurious emissions
In the Uplink (UL) path, the Remote Unit provides:
RF amplification to boost the signals received by the antennas to maintain an
excellent signal-to-noise ratio
RF filtering to reject spurious emissions
Automatic Level Control (ALC) to adjust the RF signal level to meet blocking
requirements
RF-to-optical conversion of the signal, which is conveyed to the optical port
The Remote Unit can be paired with further EUs (Extension Unit) to provide
additional bands.

4.2.4. Pole mounting procedure with screw bands
Standard mounting hardware cannot be used to mount the Remote Unit to a pole, a
column, or other similar structures. Additional hardware must be used for this type of
installation. The pole-mounting kit includes
two mounting brackets with screw bands, (worm gear) clamps to mount the
brackets to the pole
and two M8x25 screws, flat washers, and split lock washers per bracket to
attach the Remote Unit to the bracket.

- pitches figure 4-3 Pole mounting - screw bands figure 4-4 Pole mounting - fasten RU
1. Use two screw bands (B) for the upper and one for the lower bracket to fasten the
two brackets (A) to the pole.
2. Place the bands around the pole or post and feed the loose end into the lock and
tighten the slotted screw securely. When the screw is turned clockwise, it acts as
a worm drive pulling the threads of the band causing the band to tighten around
the pole.
Note: When fastening the brackets make sure that they are installed
congruently and not at an angle to each other. To determine the distance
between the clamps refer to figure 4-2 Pole mounting - pitches.
