The following general requirements must be met before installation of an indoor UMTS Macrocell site can begin:
HVAC and environmental control system installed.
All required room construction completed.
Cabinet support structures installed.
Locations for equipment marked.
Adequate clearance provided for service access.
Cable supports, racks, enclosures, and trays installed.
AC electric service installed, as described in Chapter 4, Electrical power requirements.
T1/E1, T3/E3, OC3/STM1, and user alarm facilities installed at demarcation point, as described in Chapter 7, T1/E1, T3/E3, OC3/STM1, user alarm, and Ethernet facility requirements.
Conduit for fiber cable protection system.
Alarm sensors and connection points readily available.
Interconnection equipment, such as Z-IDC blocks installed.
Cabinet anchor holes drilled.
The environment complies with limits listed in Indoor environment.
AC electric service must be installed, as described in Chapter 4, Electrical power requirements.
1-1/2 inch conduit must be installed from the AC service panel to the location of the 3GP24i power frame, as described in Chapter 4, Electrical power requirements.
Z-IDCs for T1/E1 and user alarm facilities must be installed as described in Chapter 7, T1/E1, T3/E3, OC3/STM1, user alarm, and Ethernet facility requirements
Balun Box must be installed, if required
Grounding electrode system installed
RF and GPS antenna runs installed, if required
Surge protection for antennas installed
TTLNA option
Tower light power installed (if required)
Refer to Appendix A, UMTS Macrocell site preparation checklists of this document for checklists of detailed requirements.
Floor loading must be considered during site preparation. In some cases, the cell site equipment may not rest directly on the floor. In those cases, the cell equipment will need to be supported by an intermediate structure that is fastened directly to the mounting surface. The cabinets must be supported along all four edges. The support structure must be designed in compliance with BOCA national building codes and all other applicable codes.
If required, all RF and GPS cable runs, DC inter-cabinet cable runs, AC cable runs, and facilities cable runs must be supported by a cable support and rack system. All horizontal AC and DC cables over one foot in length are required to be supported by cable support and rack system. Cable runs along the floor must be appropriately protected to prevent damage to personnel and equipment.
All architectural considerations shall comply with all applicable national and local codes, including the following:
Uniform Building Code (UBC)
Building Officials and Code Administrators (BOCA)
Southern Uniform Building Code (SUBC)
American Concrete Institute (ACI)
American National Standard Institute (ANSI)
American Standard Testing Methodology (ASTM)
National Fire Protection Association (NFPA)
