c. Real World Example 3
In this example, CEL-FI QUATRA EVO is providing wireless coverage for two cellular
operators in a six story 75,000 ft
2
building. Operator #1 (donor port A) is using an Off-Air donor
antenna because the donor signal outside the building is healthy. However, Operator #2
(donor port C) is using a Small Cell signal source, because the outdoor donor signal was
inadequate. A CU is placed on each floor, and a distributed antenna system (DAS) field is run
out from each CU to provide great coverage.
Small Cell attenuation of 60-80 dB is typical, however it depends on the small cell (target
RSSI/RSRP at the QUATRA EVO donor port should be -50dBm/-80dBm respectively after
attenuation). Consult the Small Cell Guide or contact Support for more information.
