RR 4702 - High Capacity LOS Radio Relay



Main features:RR 4702 high capacity LOS radio relay

  • HCLOS PTP radio relay with transmission capacity up to 320 Mbps
  • Harmonized frequency band 4,4 – 5 GHz (NATO IV)
  • High output power and long distance up to 90 km
  • Channel bandwith 7 MHz ÷ 56 Mhz
  • Modulation QPSK ÷ 256 QAM
  • Gigabit ethernet and E1

RR4702 High Capacity Line of Sight (HCLOS) Point to Point (PTP) radio relay based on software configuration core for building of higher organizational levels in mobile tactical networks in NATO IV frequency band. Time continuous full duplex transmission capacity up to 320 Mbps is ensured by Frequency Division Duplex (FDD). Ethernet 10/100/1000 BASE-T and E1 (2048 kbps) are standard interfaces. Local control is over PC and IP management is over webserver or SNMP.

RR4702 is very universal due to wide range of easy software setup parameters (channel bandwith 7 MHz ÷ 56 MHz and modulation QPSK ÷ 256 QAM). It can be configured to high capacity data transport in backbone net (12 - 15 km) as well as to long distance connection (60-90km) with high robustness and lower data rate. Robustness algorithms APC, ACM and FEC are included. Radio meets strict conditions for EMC and mechanical ruggedness – it is designed for extreme climatic conditions.
