DAS Architecture
Passive
DAS Architecture Examples
Scenario 1: Wireless Service Provider (WSP) 2G & 3G (Single Office/Home Office) low power
Scenario 2: WSP2G & 3G SOHO (Single Office/Home Office) low power
Scenario 3: WSP 2G & 3G Commercial Repeater
Scenario 4: WSP existing 2G & 3G (as above) with a 4G (LTE) SISO add on.
Scenario 4A:WSP existing 2G & 3G (as above) with a 4G (LTE) SISO add on.
Scenario 5: Scenario 4 with the repeater feeding an ACTIVE DAS that distributes the signal to multiple buildings where each building has multiple floors.
BDA Concerns
DAS Architecture: Active
Scenario 6: Scenario 5 where the repeater is replaced with a single sector of a BTS and the distribution area doubles justifying the capacity and requiring engineered handoff to the macro network.
Scenario 7: Scenario 6 expanded for a demanding capacity situation where WSP now has multiple sectors feeding different areas of campus and indoor handoff has to be addressed.
Scenario 8: Scenario 7 with a BTS location separated from the HE.
Scenario 9: Scenario 8 with a centralized BTS/HE location feeding multiple buildings with different sectors in a campus environment.
Scenario 10: Scenario 9 with the introduction of a MIMO to improve capacity/data rates without the addition of new frequencies.
