P501RE 1350-1390 Mhz Long Range Military Ethernet Bridge

The P501RE is a long range, very robust transparent Ethernet Bridge for L Band applications. It is ideal for applications where long range Ethernet communications is required, but an average throughput in the 100 Kbps range is sufficient. When using radio for data communications, there is always a tradeoff between throughput and range. This product provides both a long range and a significant data rate.

  • Separate diagnostic port - real time remote diagnostics and setup, transparent to network communications.   
  • Improved diagnostics - including RSSI levels in dBm, antenna VSWR and transmit current.   
  • Wide input voltage range - 6 to 30 Volt DC.   
  • The lowest current draw of any radio - at 12 Volts: 
    < 5 mA in sleep mode with no wake up delay 
    < 16 mA in idle mode 
    < 60 mA in full time receive 
    < 500 mA transmit current   
  • Improved low signal performance - RISC-based signal demodulation with matched filter.   
  • Synthesized waveform transmit data - reduces out of band modulation products.   
  • High Noise Immunity - Superior Performance in noise congested environments.   
  • Secure - Proprietary spread spectrum technology prevents detection and unauthorized access.   
  • High Speed - 115.2 Kbps continuous throughput.   
  • Long Range - 60+ mile line of sight range.   
  • Error Free Communications - 32 bit CRC with automatic retransmission.   
  • Industrial Grade Specifications -40 °C - +75 °C.

Particular features of these radios

  • Ruggedized enclosure   
  • Ethernet 10baseT interface   
  • Available in rugged or OEM board-level module   
  • 153 Kbps rate over the radio link 
  • Identical in operation to the FGR115RE (HT115RE)
