Small and mid-size venues often have wireless coverage problems that can be solved easily with an off-air bi-directional amplifier (BDA) or RF booster driving a passive distributed antenna system (DAS). For maximum effectiveness, the BDA needs to be close to the DAS headend and this is often far from where the donor antenna must be placed. If this distance is too far for a coaxial cable feed, Optical Zonu’s Antenna Extender solves this problem by providing an easy-to-install RF-over-Fiber link between the donor antenna and BDA. The link consists of the compact Antenna Unit that connects to the donor antenna and the Equipment Unit that connects to the BDA. The two units are connected by one or two strands of optical fiber to provide a robust RF connection for distances up to 3,000 ft.
The units require no adjustments and can be powered locally or remotely.
The versions currently available are:
1. Commercial Cellular: 700MHz, 850 MHz Cellular, 1900 MHz PCS, 2100 MHz AWS, 2300 WCS bands
2. Sprint 2.5 GHz TDD
3. Public Safety: 700 MHz, 800 MHz
4. Europe: Bands 20, 8, 3, 1, 7
The Antenna Unit can be installed indoors or outdoors. For outdoor installations, Optical Zonu also provides the outdoor-rated fiber cable assembly to connect the units. This cable can be fiber-only or hybrid (fiber-copper), which includes the DC power connection for the Antenna Unit.
The link is also available as a mini off-air DAS. In this configuration, the Antenna Unit is connected to an optical distribution unit that connects up to eight Equipment Units each connect to a separate BDA/DAS.
