Planning an LGCell Installation
6.2 Planning an LGCell Installation
Preliminary Planning
• Complete a preliminary system design for current requirements
Compile all of the pertinent information to determine a preliminary system design.
• Determine design requirements
Consult with the end user, the service provider, and the equipment vendors to
determine system requirements.
• Analyze floor plans
Review the building floor plans to determine approximate antenna locations and
possible locations of equipment rooms. Also, where possible on the floor plans,
check for various types of construction materials and installation restrictions.
Preliminary System Design
• Compute equipment requirements for current traffic rates
Base this on the voice channels required and equipment parameters of the base sta-
tion specified for the system (requires input from service provider RF Engineer).
• Compute equipment requirements for expansion to future traffic rates
Base this on customer requirements and equipment parameters of the base station
specified for the system.
• Make recommendations for a system design for future traffic requirements
Provide a possible migration plan to achieve future capacity and coverage require-
ments, perhaps including provisions for additional equipment and/or sectorization
of the existing cells.
Site Survey
• Conduct on-site RF site evaluation
Conduct in-building signal level tests after the preliminary design is completed.
Using a test transmitter, introduce an RF signal at the approximate antenna loca-
tions and record the signal levels on a copy of the floor plan.
Conduct a physical review of the building to determine types of construction mate-
rials in the floors and walls, and amount of “clutter” in the building. (Clutter is
anything that can block or reduce the RF signal coverage.) These will help deter-
mine the expected coverage area; the in-building signal loss due to walls, furniture,
equipment, people, etc.; and the proposed equipment locations and cabling require-
ments.
Identify AC power requirements and extra equipment (cabinets, cable trays, cable
racks, etc.)
