Page 36 FlexWave Prism Host, Remote and EMS 5.1 System Reference

The FlexWave Remote supports or provides the following basic functions:

•• Receives on the forward path the digitized spectrum from the Host and converts

the spectrum back into an RF signal to be distributed via an externally mounted

antenna system. On the reverse path, the Remote digitizes the designated RF

spectrum and digitally transports it over single mode fiber or Millimeter Wave

(MMW) to the Host.

•• Provides RF interface (antenna port) for the antennas.

•• Accepts AC power input.

2.3.1 Handset Interface

The Remote interfaces with the handsets (cell phones) through an antenna. In the

reverse path, the Remote receives RF signals from each handset (see Figure 1-3 on

page 9). The Remote digitizes the RF signals and then converts them to digital optical

signals for transport to the Host over the optical fiber link. In the forward path, the

Remote receives digital optical signals from the Host. The Remote converts the

optical signals to RF signals for transmission to the handsets.
