4 Site Preparation for Node B Installation
4.1 (Step 4) Conduit Installation
Conduit is typically required between the INC and the Power source. In the case of the outdoor
installation the INC and power source are housed in the same cabinet. Power and Ethernet cables
are to be pulled through the conduit, one power cable and one Ethernet cable for each Node B. If
external alarms are to be utilized conduit may also be necessary between the external alarm
device and the Node B for monitoring the alarm.
4.2 (Step 5) Antenna and Coax installation
Antenna’s and coaxial cable should be available at the site, and are part of the construction
checklist. Two antennas per Node B are required, therefore two coaxial cables per Node B
should be available.
Cables should be properly marked to indicate what antenna the coaxial cables are to be
connected to the Node B serving the sector or area.
The coaxial cables are to be terminated to a lightning arrestor and a jumper installed to the
proper length between the lightning arrestor and the Node B location.

4.3 (Step 7) GPS
For proper operation of the GPS receiver, the Node B must have a clear southern view of the sky.
A site survey should be done before Node B installation to verify that the Node B installation
location is suitable for GPS reception. A simple survey method is to take a handheld GPS
receiver to the site and verify that GPS lock is obtained in the location of the Node B installation.
The handheld GPS should be able to obtain a “locked” condition within 2 minutes of power-on,
and should be able to see a minimum of 4 satellites at all times. Note that when the Node B is to
be installed on or near a tower or building wall, the GPS survey should replicate this
configuration exactly.

5.3 (Step 6) Grounding Installation and Inspection
Grounding materials used for the node consist of #2 AWG BCW tinned-ring solid copper wire
leading from the ground lug on the right rear section of the node to the grounding buss bar. The
grounding wire crimps on a double lug lead going from the buss bar to a grounding ring via a
Cadweld (exothermic) ground ring. A typical ground ring consists of eight foot long stainless
steel ground rods which are 5/8” diameter. Although each site will be designed for that specific
site installation.

5.6 Backhaul Connections to INC
The Node B currently requires one 100 BaseT connection to a serving INC. Future
enhancements will enable (4) T1's for connection to a serving INC. The connections are labeled
and shown in the figure below.
If the Node B is in not in the same site location as the serving INC, there must be no greater than
a 5 millisecond delay on the backhaul connection. This can be provided by microwave or land
based facilities with a very high reliability rate of 99.9995%.
Terminate the Ethernet cables with RJ48 connectors and strip the wire to allow proper
connection to the earth bar. Test the continuity for the Ethernet cables with test equipment
consisting of a main and a remote unit.
The termination for these interfaces is specified within the datasheets for the interfaces. The
specification for both cables should be CAT5 - 4 pair, screened cable, recommended Alcatel
LANmark-5 F2TP or equivalent.

5.11 GPS
5.5.1 GPS Operation
The Node B has an integral GPS antenna and receiver, as shown in figure above. The GPS
timing signal is used by the Node B for the TDD frame timing, so that all Node B’s in a network
are synchronized. The GPS signal is also used by the master oscillator for a frequency reference.
The Node B can operate for several hours after a loss of GPS timing but a gradual drift of the
frame timing will result in system interference and a loss of handoff capability.
The GPS receiver is automatically enabled when the Node B is powered and there are no
adjustments or settings to be made by the user.
After installation of the Node B, verify proper operation of the GPS receiver by connecting the
Local Maintenance Terminal (LMT) to the LMT port and accessing typing “gpsstats”.
5.5.3 GPS Repeater Installations
A GPS repeater functions as a reradiating repeater to provide a GPS signal in areas that do not
have a clear view of the sky. The repeater consists of an active antenna, a repeater block, a
passive antenna, connecting cables and a +12VDC supply
The location of the active antenna should be chosen so that the antenna has a clear view of the
sky. A suitable location can be verified before installation by checking for GPS lock with a
handheld GPS unit. The repeater block and passive antenna are installed in the coverage area
(Node B location). The +12VDC supply can be provided by a wall transformer that is connected
to a UPS.
After installation and power-on, verify that the handheld GPS unit is able to obtain GPS lock
inside the Node B installation area. If not, make adjustments to the antenna locations as required
until the handheld GPS receiver can obtain lock. After the Node B is installed, verify that the
Node B GPS receiver is able to obtain and keep GPS lock condition.
