1 GENERAL
The FlexWave URH product family of products is intended as a “next generation” distributed
antenna system (DAS). DAS products provide bidirectional transport of digitized RF spectrum.
Each link consists of a host unit (providing the interface between the base station RF ports and the
optical fiber) and at least one remote unit (providing the interface between the optical fiber and the
remote antenna). The difference in this product is the high-speed digitalization of a wideband
portion of spectrum, that allows for transport of RF signals over extended distances, without the
RF degradation that normally results when analog systems are impacted by optical effects.
The basic function of the FlexWave URH platform is to transport via fiber optic cable RF
signals form a Base Transceiver Station (BTS) to an antenna interface allowing communication
to a mobile device. Multiple BTS communication paths are allowed over a single URH system.
Diversity receive is supported. A block diagram of the system is shown in
Figure 1.

The basic function of the FlexWave URH simulcast (point-to-point) platform is to transport, via
fiber optic cable, RF signals form a Base Transceiver Station (BTS) to multiple antenna interfaces
allowing communication to a mobile device. Up to 8 simulcast remotes are supported.
