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

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
