MR400 Radio Modem

MR400 Radio Modem



MR400 is awell proven radio modem, on the market for over a decade and undisputably well established. Tens of thousands units serve reliably around the world, fromthe poles to the equator.

MR400 uses a sophisticated anti-collision protocol on the Radio channel. Its unbeatable network performance is boosted by the unique implementaion of proprietary SCADA protocols fromall significant vendors on the SCADA market.

Thanks to MR400 extraordinary intelligence, speed and switching time, they are suitable for all types of networks where emphasis is placed on speed and reliability, such as SCADA & Telemetry for utility distributions (water, electricity, oil&gas), SmartGrid power networks, Transaction networks like lottery, ATM or POS, mobile networks including mission critical fleet management and many other applications.

  • Max. distance more than 50 km
  • High resistance to multi path propagation and interference (CPFSK modulation)
  • Every  can work simultaneously as a repeater
  • Hybrid networks: - any IP network (Internet,3G/GPRS etc.) can interconnect MR400 units
  • Unlimited number of radio hops

Mobile network

  • Connection-less Mobile mode in Radio protocol 
  • Every stationary unit can serve simultaneously as a Base station for mobiles Cell architecture: automatic instant hand-over, each individual packet from mobile is delivered via the best Base station at the moment 
  • Central MR400 maintains a list of “mobile-base” connections, updated with every packet, to enable communication from the centre to mobiles 

Fast to configure and diagnose

  • Setr - special Windows or Linux application for configuration 
  • The fastest and most robust remote access with minimum data over the network
  • Monitoring of User interfaces and Radio channel, either locally or remotely
  • On line as well as historical statistics for all interfaces and Radio channel

RANEC - Network Management

  • Collects statistics from all units and save them in database Extra load generated by RANEC is automatically regulated based on user traffic
  • One server + unlimited number of graphical clients Possible to display all statistics in graphs
  • Displays the network topology on a background map Network planning  - it calculates the coverage using digital model of the terrain

Security

  • Licensed radio bands
  • FEC, interleaving, proprietary data compression 
  • CRC32 data integrity control on Radio channel Proprietary protocol on Radio channel with packet acknowledgement
  • Blowfish 160 encryption
  • Netlock - application which enables/disables remote access to the unit for three level of users

Reliability

  • Every single unit tested in a climatic chamber as well as in real traffic
  • Military or industrial grade components are used
