Node B Installation Guide DRAFT 1 OVERVIEW Node B is the European Technical Standards Institute’s (ETSI) name for the radio base station. The basic function of the Node B is to convert 100 Base T packet data into the UTRAN TDCDMA air interface used between the Node B and the 3G Modem. The Node B can be configured to operate in configurations ranging from a single sector or omni mode, up to a 6 sector arrangement.

Node B Installation Guide DRAFT 3 (Step 3) MOUNTING THE NODE B BRACKET There are three ways of installing the Node B – Wall, Pole and Rack Mounts. This section explains the three different mounting types with the installation and powering procedure for each type of mount. PRECAUTIONS The following precautions and checks are applicable to all mounting types. Leave blanking plugs over all connectors until they have been connected to the appropriate cabling.
Node B Installation Guide DRAFT 3.1 WALL MOUNT W ALL MOUNT ASSEMBLY General Safety Precautions: • Wall construction is able to support the weight of the unit assembly. • Proper grounding 3.1.1 Mounting Considerations Consider the earthquake zone requirements for the given site being considered. Ensure that the mounting location complies with these considerations. Review the GPS installation guidelines to ensure that the location will allow proper operation of the Node B. I.e.
Node B Installation Guide DRAFT 3.2 POLE MOUNT POLE MOUNT ASSEMBLY Illustration 3 shows antenna and mounting brackets fixed on an aluminum type pole. • • • General precautions – Do not install in winds over 40 Mph. Do not install when lightning is closer than 2 miles. Do not attempt to install in rain. 3.2.1 Mounting Considerations Consider the earthquake zone requirements for the given site being considered. Ensure that the mounting location complies with these considerations.
Node B Installation Guide DRAFT 3.3 RACK MOUNT RACK MOUNT ASSEMBLY General Precautions 3.3.1 Mounting Considerations Consider the earthquake zone requirements for the given site being considered. Ensure that the mounting location complies with these considerations. Review the GPS installation guidelines to ensure that the location will allow proper operation of the Node B. I.e.
Node B Installation Guide DRAFT 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.
Node B Installation Guide DRAFT 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.
Node B Installation Guide DRAFT 4.5 (Step 9) External Alarms If local alarms are to be utilized for a terminal block has been provided on the Node B termination panel. The specifications for those interface requirements are below. 4.5.1 Alarm Input Specification The alarm inputs from the Node B Patch board to the digital board shall be TTL levels and active high. The external alarm inputs shall be opto-isolated current loops. The voltage and currents shall be supplied by the external source. 4.5.
Node B Installation Guide DRAFT 5 (Step 10) PHYSICAL INSTALLATION OF THE NODE B 5.1 Placing the Node B into the Rack It is assumed that the unit has been removed from the packing crate and that all materials are checked and present, further that all the site preparation has been planned. Sighting the NodeB The first priority in sighting the NodeB is that the GPS antenna can ‘see’ the sky and therefore the satellites. See section 4.4 for further guidance.

Node B Installation Guide DRAFT The conduits must be fixed to the brackets prior to fixing the bracket to the wall. Leave a sufficient loop of cables to enable them to be prep’d back to the appropriate length. Looped Cable The following figure specifies the way the conduit bracket glands have been designated signifying which cables should be fed thru which gland.

Node B Installation Guide DRAFT 5.2 Service Area Interfaces The following figures illustrate the key elements for reference in the cable interface service area of the NodeB. The ground connection is at the rear of the unit see below.
Node B Installation Guide DRAFT 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.
Node B Installation Guide DRAFT 5.4 Cable Clamp Seal Remove the cable clamp by loosening the 4xHex-Socket head screws, see figure below.
Node B Installation Guide DRAFT 5.5 Connecting Power to the Node B The power supply can be either universal ACDC coverter of 300W, universal input range of 90 to 240Vac with a 12Vdc output or a –48Vdc input to 12Vdc output. • Cable preparation – Specification: terminal blocks maximum cable size 2mm2 (14AWG) & maximum size of outer diameter 7mm.
Node B Installation Guide DRAFT 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.

Node B Installation Guide DRAFT 5.7 Alarm Connections The description of the alarms is as follows Alarm Inputs The alarm inputs from the Node B Patch board to the digital board shall be TTL levels and active high. The external alarm inputs shall be opto-isolated current loops. The voltage and currents shall be supplied by the external source. Alarm Outputs The alarm outputs from the digital board to the Node B Patch Board shall be TTL levels and active high.

Node B Installation Guide DRAFT 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.
