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.
