1.4. Compliance

1. Notice: For installations which have to comply with European EN50385 exposure

compliance requirements, the following Power Density limits/guidelines (mW/cm²)

according to ICNIRP are valid:

o 0.2 for frequencies from 10 MHz to 400 MHz
o F (MHz) / 2000 for frequencies from 400 MHz to 2 GHz
o 1 for frequencies from 2 GHz to 300 GHz

2. Notice: For installations, which have to comply with FCC RF exposure

requirements, the antenna selection and installation must be completed in a way to

ensure compliance with those FCC requirements. Depending on the RF frequency,

rated output power, antenna gain, and the loss between the repeater and antenna,

the minimum distance D to be maintained between the antenna location and human

beings is calculated according to this formula:

]/[

][

][

2

4

cmmW

mW

cm

PD

P

D







where

• P (mW) is the radiated power at the antenna, i.e. the max. rated repeater
output power in addition to the antenna gain minus the loss between the
repeater and the antenna.

• PD (mW/cm²) is the allowed Power Density limit acc. to 47 CFR 1.1310 (B) for
general population / uncontrolled exposures which is

o F (MHz) / 1500 for frequencies from 300MHz to 1500MHz
o 1 for frequencies from 1500MHz to 100,000MHz

RF exposure compliance may need to be addressed at the time of licensing, as
required by the responsible FCC Bureau(s), including antenna co-location
requirements of 1.1307(b)(3).

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. 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.

The ION-U system includes high power and low power Remote Units designed to meet
the specific requirements of a given DAS. An ION-U Master Unit can support both high
power and low power RUs simultaneously.

2.2. ION-U Low Power Remote/Extension Units

The ION-U Low Power Remote Units are scalable and integrated with up to:

• 5-band (Cell700, LMR800, Cell850, PCS1900, AWS-3 1700/2100) or

• 6-band with additional Extension Unit

• 7-band with two additional Extension Units

SISO capability. Two RUs can be operated as a pair for MIMO operation. These units
are compatible with analog, GSM, EDGE, IS-95, CDMA2000, EVDO, W-CDMA,
HSDPA, LTE and iDEN modulation standards. 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.

4.2.6. Antenna connection

The Extension Unit has six 4.3-10 connectors. For mounting the cable connector, it is
recommended to refer to the corresponding documentation of the connector
manufacturer. The bending radius of the antenna cables must remain within the given
specifications.

The selection of cable and antenna is an important consideration. Choose the type of
cable best suited for the antenna. Consider that a cable with higher loss is less
expensive but impairs performance.

Notice: Use an appropriate torque wrench for the coupling torques:

- for N-type connectors (2 N-m / 20 in lb) with 13/16 in opening,
e. g. item no. 244379 available from the CommScope e-catalog

- for 4.3-10 type connectors (5 N-m, 44 in lb) with 22mm (7/8) in
opening

Do NOT use your hands or any other tool (e.g. a pair of pliers). This might cause
damage to the connector and lead to a malfunction of the unit.

Attention: To minimize passive inter-modulation (PIM) distortion, attention has to be

paid to the physical condition of the connector junctions:

• Do not use connectors that show signs of corrosion on the metal surface.

• Prevent the ingress of water or dirt into the connector.

• Use protective caps for the connectors when not mounted.

• Before mounting clean the connectors with dry compressed air.

• Before mounting clean the mating surfaces of the connector with a lint-free

alcohol-drenched cloth on a wooden or non-metallic item.

• Attach and torque the connectors properly.

• Avoid metallic abrasion when mounting the connectors by only screwing the

connecting nut, but not turning the whole connector.

• Use a torque wrench to fasten the connector, see above.

• Clean the protective caps before mounting for antenna cable replacement.
