  • FR-100 #4 is an advanced version of FR-100 #1.
  • Up to 10 simultaneous IP-connections of any topology.
  • Capable of working in multicast mode in networks that do not support the given mode on their own.
  • Allows measurement and transmission of the receive signal (RSSI) over IP-network.
  • When transmitter coverage zones overlap, use can be made additionally of a special Voting Server (optional) to collect all such signals, determine the best one and retransmit it to all base stations connected via FR-104 gateway. In case IP-communication with the Voting Server is lost, the gateway switches to the independent local repeater mode. Analysis of information on the signal received by different base stations is ensured continuously to provide seamless handover of a fast moving subscriber.

fr104 EN2

Application

  • Radio remote control
  • Integration of up to 10 radio communication zones into a single network (with a possibility of overlapping coverage zones)
  • Capable of switching several different radio communication networks without using “Switching” software module of the “Dispatcher” software.
  • Provides continuous radio coverage for highways and complex infrastructure sites. In case of a highway, it is sufficient to have three nominal frequencies – one for reception, and two alternately for transmission

Compatibility

  • Software: SINDIS FR-SF, “Dispatcher” software, “Switching” optional module
  • IP-devices: FR-100 #1/#6 Votinger Server, Remote Voice Logging Recorder, DVC
