These instructions will cover planning for your Cel-Fi QUATRA system.
- Site Address (useful to view building on Google Earth)
- Define project scope (sq. ft, operators of interest, # floors, ceiling types)
- Request floor plans and optional interior photos (usage)
- Identify interior hollow vs. masonry walls
- Ask for known problem areas (they know, and they have expectations!)
- How can a site Internet Connection be provided?
- Where are existing roof penetrations and IT closets?
- Visit the Site if possible
- Take pictures (usage, ceiling types, etc).
- Measure service by Carrier (apps like Network Cell Info Lite & Speedtest)
- Where is service poor or ok?
- What side of roof or building gets best service now (by Carrier)
- Annotate readings on floor plans
- Confirm interior wall construction, IT closet space, low voltage cable routes)
- Determine NU locations and coax lengths to donor antennas
QUATRA BOM Estimator
Estimate the percent (%) of each area type:
Enter the values into the Estimator tool:
Determine CU Locations
Approximate Coverage Radius per area type (assuming good NU-CU isolation):
Rough CU placements:
Adjust CU Layout
Adjust number and placement of CUs depending on # floors or building shape:
IMPORTANT! If installing multiple systems, such as a four carrier solution using 2 Cel-Fi QUATRA 2000 systems, then adjust your hardware plan BOM for the 2 systems.
CUs moved toward areas of higher wall density, and to take advantage of open areas and hallways.
Donor Antenna Placement
Signal analysis or speed tests can help determine the best Donor Antenna location:
Always use the directional antenna for the Cel-Fi QUATRA 1000. For the 2000, if all operator donor signals are good quality or better, use the dual feed Omni Donor Antenna. Otherwise order and aim dual feed MIMO Directional Antenna to improve signal quality.
Best if Donor Antenna cable and splitter losses do not result in less than -90 dBm RSRP into each network unit radio:
