This document summarizes a distributed antenna system (DAS) project at DirecTV's corporate headquarters that was designed and implemented by Advanced RF Technologies. The initial system was installed for Verizon Wireless but was modularly expanded over time to add AT&T, T-Mobile, and Sprint. The modular ADX DAS solution allowed each carrier to connect to the system individually. The DAS provides in-building wireless coverage across multiple buildings and floors and part of the parking garage. While the current system capacity needs are being met, the modular design leaves room for future growth through additional carrier connections, small cell integration, or expanded coverage areas.

Summary: Ready for Growth
Modularity = Flexible and Future Ready
o Sprint has yet to deploy with 800MHz (CDMA, LTE)
& 2500MHz (TD-LTE), capacity not needed
currently
o Carriers yet to plug-in w/ Small Cells, extra capacity
not needed
o Minimal areas left to optimize
o Additional parking garage coverage may be added
o Public Safety (ex. UHF/VHF)?
o Remote Access/Alarming?
