In-Building ApplicationsHow to Differentiate Your Service
Moderated by: Dominic C. VilleccoPresident of V-COMM, L.L.C.
2010 Business & Technical Conference
RF over Fiber – 4 Basic Applications and Advantages
• Connecting to the Donor site (Direct feed from BTS)– Eliminates unwanted signals from entering– Consistent signal quality / level– Link budget (no signal loss)– Control Uplink signals (C/N; coverage footprint)
• Between buildings (campus-wide connections)– Consistent signal quality / level– Link budget (no signal loss)– Cost-effectiveness– WDM Solutions available
Wireless In-Building Coverage Solutions
RCA BTC Conference 2010 –Welcome to Myrtle Beach!
•In‐building Coverage Requirements• Typical Projects • BDA Products • System Architecture• Fiber‐Optic Solutions• Turn‐key systems• Combining 2‐Way Radio and Public Safety comms•Other services (WiFi; WiMAX, etc.)• Outdoor DAS

RF over Fiber – Applications and Advantages, cont’d
• Within buildings (DAS applications – connecting antennas and amplifiers)– Modular, scalable architecture– Link budget (no signal loss)– Cost-effectiveness (Less expensive than coax)– Much lower installation cost
• Remoting antennas (GPS applications)– Consistent signal quality / level– Link budget (no signal loss)– Light weight and portable
