Host Unit
The rack-mountable FlexWave Prism Host Unit is typically located at a Base Station or a facility housing
a suite of Base Stations. On the forward path, the Host Unit receives the RF signals from the BTS and
digitizes the designated RF bands and digitally transports them over single mode fiber or a millimeter
wave link to the Remote Units. On the reverse path, the Host Unit receives the digitized RF signals from
the Remote Unit and converts them back to RF for the BTS.
The Prism Host Unit is completely modular in design. Digital/Analog Radio Transceiver (DARTS) are hot
swappable providing easy upgrades to addtional bands without interrupting existing service.
The Prism Host Unit supports up to eight DART cards (supporting up to eight Remote Units) and
is capable of simulcasting signals up to as many as eight Remote Units.
The Host Unit utilizes an embedded element management system for system configuration and network
monitoring. The embedded EMS collects alarm information from both the Host and Remote Units. For
multiple link deployments, multiple Host Units can be networked together at the same BTS site.
In addition to sending alarm notifications to the Element Management System (EMS) through software,
the Prism Host Unit also features front panel alarm reporting. LEDs on the front panel of the Host Unit
will change color depending on the status of the unit. LED displays provide information regarding the
following items:
