2. Introduction
Page 14 M0200ABA_ION-U_EU_H_23_23 User’s Manual for ION®-U
2. Introduction
2.1.Purpose
Mobile telephone and public safety 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. Extension Units can be connected to
Remote Units to provide coverage for further bands. 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.
2.2. ION-U High Power Remote and Extension 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
Remote Units and SISO and MIMO operation.
The ION-U EU H 23/23 is a SISO and MIMO Extension Unit used in conjunction with
a Remote Unit in the ION optical distribution system. This system transports up to
two frequency bands simultaneously (WCS2300 MHz), providing a cost-effective
solution for distributing capacity from one or more base stations.
It has been specifically tested and optimized for UMTS, HSPA+, LTE, and OFDM
modulations. Furthermore it is provisioned for future modulation scheme evolutions.
These Remote and Extension 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.

2. Attention: Due to power dissipation, the Extension Unit may reach a very high
temperature. Ensure sufficient airflow for ventilation.
3. Notice: Exceeding the specified load limits may cause the loss of warranty.
4. Notice: When connecting and mounting the cables (RF, expansion, mains, ...)
ensure that no water can penetrate into the unit through these cables.
5. Notice: Ensure that there is free access to the electrical connections as well as
to the cabinet. The approved bending radius of the connected cables must not be
exceeded. See chapter 7.1 for more details.

6. Notice: If any different or additional mounting material is used, ensure that the
mounting remains as safe as the mounting designed by the manufacturer. The
specifications for stationary use of the Extension Unit must not be exceeded.
Ensure that the static and dynamic strengths are adequate for the environmental
conditions of the site. The mounting itself must not vibrate, swing or move in any
way that might cause damage to the Extension Unit.
7. Notice: Observe all additional rules or restrictions regarding mounting that apply
to specific Extension Unit types. For details refer to the mechanical specifications
in the data sheet for the unit. Install the unit vertically with the fan unit at the top.
A maximum tilt angle of 25° from a vertical position must be maintained, as
shown in the following illustrations:
8. Notice: A spacing of 40 mm (1.58 inch) around the unit is required.
9. Notice: To ensure sufficient airflow when mounting the unit in enclosed spaces,
two lid openings (one for the air inlet and the other for the air outlet) must be
provided. Do not block these air inlets and outlets when mounting the Extension
Unit. The size of each opening must equal at least 18 x 18 cm (> 300 cm2).
Ensure that there is no thermal short circuit between the air inlet and air outlet.
Make sure free airflow is not deflected or otherwise obstructed.

4.2.4. Wall mounting procedure
Notice: It is the responsibility of the installer to verify that the supporting surface will
safely support the combined load of the electronic equipment and all attached
hardware and components and to ensure that the EU is safely and securely
mounted.
1.
Mark the position of the drilling
holes (for pitches refer to figure
4-2 Wall mounting)
. Drill four
holes at the marked positions and
insert dowels*.
2. Mount the brackets (A) to the wall
using the
M8x80 screws (B), split
lock washers (C), and
washers
(D).

3. Hang the Extension
Unit into the upper
bracket, insert it to the lower bracket,
and
fasten it to the low
er bracket with the
M8x25 screws (E), split lock washers (F),
and washers (G).
* The dowels are not included with the delivery because the suitable type depends on the on-site

4.2.5. Pole mounting procedure with screw bands
Standard mounting hardware cannot be used to mount the Extension 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 Extension Unit to the bracket.

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.
FNote: 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 4-3 Pole mounting - pitches.
