Regional Tool Facility.
System and RF Design Specification
The Picocell installation should first be specified by a qualified RF
engineer for optimum placement of transceivers and performance. The
system specification details traffic and coverage requirements. If this
is not possible the Field Service personnel will have to conduct
extensive coverage testing after turn up to ensure critical areas receive
RF coverage and to identify areas where coverage may be limited. See
NTP XXX XXX for deployment guide lines and RF planning.

3.1 Precautions
Observe the general safety precautions against personal injury and
equipment damage outlined in the ISM/IM0 at all times.
Indoor Installations only.
This method is for indoor installations only.
Picocell 1900 transceivers and antennae are for indoor installations only
and mounting of some or all; transceivers, antennae, hybrids and cabling
in an outside environment may create a potential fire hazard from
lightning. Custom design is required to address outdoor requirements
Avoid thermal trapped air cavities. In particular, the Picocell cannot be
mounted above the ceiling as this is deemed a plenum installation, and
different, tighter safety specifications are enforced.
CAUTION
Maintain minimum or greater distances from interference
sources and from equipment and apparatus which may be
affected by RF energy.
3.2 Preparations
Prior to starting the operations presented in this method, arrange all
materials, tools, and test equipment at the work location so as to
minimize fatigue and inconvenience.

4.0 Installation Requirements
PICOCELL 1900 employs dual transceivers, which are distributed in a
typical commercial building environment. Standard building telephone
wiring connects the TCM digital link between the transceivers and the
CSI. The CSI in the building location connects to the MTX over
standard Telco digital T1or E1 facilities. Transceivers are equipped with
internal Omni antennae and provide RF coverage from a wall or ceiling
location. External antennae options are also supported and described
here.
To provide flexibility in providing RF coverage in building
environments and to provide flexibility in meeting traffic requirements
the PICOCELL 1900 transceivers may be connected to external
antennae either directly or combined through RF hybrids. Flexibility in
RF coverage may also be enhanced with external antennae connected
directly to the transceiver and the antenna placed for optimum RF
coverage around barriers and obstacles and in select areas.
The RF channels in the individual PICOCELL 1900 transceivers are
equipped with duplexed transmitters and dual receivers to provide path
diversity in the mobile to base station path. The transmitters are hybrid
combined internally to both antenna ports which are also duplexed to
each receiver. Therefore RF signals from each antenna port connecting
to the dual receivers provide diversity over two RF paths.
Traffic capacity and RF coverage may also be optimized by combining
several transceivers on several antennae through multi port RF hybrids,
each antenna providing coverage for multiple RF channels. Refer to
NTP-XXX-YYY for deployment rules governing RF coverage and
traffic requirements.
Three configurations are supported:
•
1. DISTRIBUTED TRANSCEIVERS
•
2. DISTRIBUTED ANTENNAE
•
3. COMBINED TRANSCEIVERS AND DISTRIBUTED
ANTENNAE.

Distributed Transceivers
One or more transceivers equipped with internal antennae are
distributed through an indoor building environment as shown in Figure
2. RF coverage and traffic engineering rely on the coverage area and
traffic capacity provided by the physical placement of each transceiver.
Using this arrangement, filling in high traffic areas and spot coverage
requires the placement of individual transceivers at central points in the
desired coverage area. Traffic capacity is determined by the number of
Picocell transceivers in the coverage area. The TDMA 1900 mobile
units are served with Digital traffic channels and Digital Control
channels as determined by rules outlined in the Picocell Deployment
Guide.
Figure 2 – Distributed Transceivers

September 3, 1998
Method 04-0242
External antennas may be connected to the Picocell transceivers and
located remotely from the transceiver location. This provides flexibility
for optimizing RF coverage and working around restrictions for
mounting the transceivers. The internal antennae equipped in each
Picocell transceiver is disabled when remote antennae are connected and
permits the RF coverage area to be determined by placement of the
antennae and not the transceiver. The remote antenna option can be
used to provide coverage over shadowed areas where physical
deployment of the transceiver has an obstruction which blocks RF
coverage and where it is impractical to locate the Picocell transceiver

Combined Transceivers and distributed Antenna.
Transceivers may be combined with multiple antennas to increase both
traffic capacity and RF coverage in a cell partition. Figure 4 shows the
distribution of external antennas with two transceivers combined
together. Hybrids are used to combine two to four Picocell transceivers
with an external antenna network up to 8 antennas. Combining uses
either a dual 4 port or dual 8 port combining hybrid. The dual 4 port
hybrid has 4 inputs and 4 outputs and connects all 4 RF channels to each
of the 4 antennas. The dual 8 port hybrid has 8 inputs and 8 outputs and
connects all 8 RF channels to each of the 8 antennas. Low-loss coaxial
cables connect between the antennae, hybrids and transceivers. See IM
12-0152 for cable types.
Figure 4 illustrates a multi floor application with distributed antennas
on 2 floors and the combined transceivers mounted on the first floor.
Antenna placement and resulting coverage must be determined by the
System Engineer and should be listed in the System design and layout
document. Ensure system layout and mounting information is available
before starting the installation.

Method 04-0242
Multiple Picocell transceivers may be combined on antennas using
hybrids. Each picocell transceiver connects to two antennas which may
either be internal to the unit or cabled to external antennas. The
transmitters of both RF transceiver channels are combined through an
internal hybrid to broadcast on each transceiver antenna port. External
hybrids are used to connect multiple Picocell transceivers to multiple
antennae as shown in Figure 5 and Figure 6.

4.2 Picocell Physical Site Requirements
Installation of the Remote antenna option must consider mounting of
antennae, transceivers, the interconnecting coaxial cable and TCM
wiring. Cables must be supported in cable tray, routed in conduit or tied
in intervals and must not violate building and fire codes. The System
design Specification and layout must specify these parameters to ensure
that the cable types and routes meets building codes.
transceivers and antennae must not be mounted behind obstacles and if
it is impractical to do so then external antennae may be required.
Mounting constraints on antennae are more flexible due to the lighter
weight and smaller size. The ceiling antenna may be secured directly to
ceiling panels and the directional antenna to dry wall surfaces using
common anchor hardware. The Picocell transceiver requires support for
ceiling mounting. See IM 12-0152 and IM 02-0245 for mounting
details.
Installation of the combined Picocell applications require the
transceivers to be cabled to an external hybrid combiner. This will
operate multiple transceivers to serve a large area on antennas
distributed throughout the building. The antennae are connected to the
hybrid combiner by low-loss coaxial cables. Mounting of the Hybrids,
transceivers and cabling must consider the cable routing options, power
options and location. It may be required to provide a plywood back
board to support the combined Picocell transceivers and hybrids.
Transceivers co-located with power supplies will require individual AC
outlets at the transceiver locations. IF transceiver power is remoted from
the CSI location then outlets must be provided to accommodate all
power convertors, see next section: "Picocell Power"

4.3 Picocell Remote DC Power
Picocell power may be remoted through station wiring or co-located
with the Picocell transceiver. Co-located power requires an AC outlet
close to the Picocell transceiver. Refer to the System Design
Specification to confirm AC outlet requirements.
Remote power requires that the cable resistance be accounted for in
order to ensure that the voltage drop over the pair does not reduce the
voltage below minimum requirements at the Picocell transceiver. More
conductors may be employed to reduce voltage drop and pairs may be
doubled up to meet the resistance requirements. Table 1 on page 16
outlines the maximum length of 24 AWG cable allowable between the
Picocell transceiver and the remote AC/DC power convertor. The
following assumptions have been made:
24 AWG twisted pair
-48 volts minimum from the AC/DC convertor
-30 volts minimum into the Picocell transceiver

Note: To calculate the distance with 26 AWG wire, scale distances by 0.629 To
calculate the distance with 22 AWG wire, scale distances by 1.599
Note: The Picocell nominal maximum DC power drain design is 32W. The DC
distribution range is limited since the PUPS will shut down if the voltage drops
below -30V. The 36W range numbers should be used for the worst case for
maximum load, all transmitters on.
It is expected that a typical, in-building connection from the Picocell
will be via 4-pair station wiring, with 2-pair for DC powering, and 2-pair
for the TCM feeds. Figure 7 illustrates the picocell transceiver
terminations on the MDF terminal block. This arrangement is intended
to isolate ground and battery on the block to minimize accidental
shorting.

4.5 Environmental
•
The room must be clean and well ventilated. Each Picocell
transceiver can dissipate up to 40 Watts maximum of power in the
form of heat( 134 BTU per hour.) Equipment ventilation must be
sufficient to maintain the temperature at an acceptable level.
•
Indoor use only, cabling, antennae, hybrids and Picocell
transceivers.
•
Avoid thermal trapped air cavities. In particular, the Picocell cannot
be mounted above the ceiling as this is deemed a plenum
installation, and different, tighter safety specifications apply.
•
The acceptable temperature levels are listed below:
•
5o and 40o C (41o and 105o F) Continuous Operation
•
The humidity is maintained between 5% and 90% RH (noncondensing) at 40o C worst case temperature and not to exceed 0.024
lbs of water per pound of dry air for continuous operation.
•
The Picocell will function from the altitude of 60m (197ft) below sea
level to 4000m (13,000ft) above sea level. The maximum
operational temperature requirement will be de-rated by 2oC (3.6oF)
per 304m (1000ft) for altitudes above 2134 m (7000 ft).
•
The location selected to mount the Picocell is not subject to constant
vibration.
•
The Picocell is located at least 12ft (3660 mm) away from any
source of electrostatic and electromagnetic energy. These sources
may include:
