Embedded Maritme Broadband Radio - EMBR



WORLD CLASS – through people, technology and dedication


      Existing broadband systems
      • Ruggedized WiFi/WLAN 802.11x
              • Stability
              • Path Loss Margin: Up to 150 dB with multiple high
                gain sector antennas
              • Does not handle a combination of short/long
                ranges
              • Limited real time capability
      • WiMax (802.16e)
              • Requires base station
      • Radio link systems with parabolic antennas
              • Only point-to-point
              • Antennas need motor-control to maintain track

      EMBR - Main features

      • Embedded component in reference systems
      • EMBR provides the user with one or more
        reliable broadband data links
      • EMBR is easy to configure and operate
      • EMBR has no moving parts
      • An EMBR data link is able to transfer 5Mbps
        when the distance between the nodes are up
        to 10 km
      • Realtime capability

      EMBR Design


      • Frequency Band: 4.900 – 5.875 GHz

      • Bandwidth: 20 MHz

      • User Datarates: Up to 6Mbps

      • Output power control

      EMBR - Design
      • Smart antenna based radio system with
        60 antennas/transceivers in each unit
      • Maximum Transmitted power:
        60 x 100mW = 6W (38 dBm)
      • Antenna gain: 26 dBi (8 dBi + 10log60)
      • Gives maxmimum EIRP: 2.5 kW (64 dBm)
      • Antenna 3 dB beam width: +/- 4.5° (H and V)
      • Antenna beam can be controlled +/- 45 °
      • All beam forming is performed in the signal
        processing domain

      EMBR MAC/PHY
      • Tailored Media Access Control (MAC) and
        Physical Layer (PHY)
      • ACCM modulation (DSSS with rotating m-ary
        code book)
      • Improved immunity versus multipath fading
        (reflections from sea surface and steel
        structures)
      • Multi purpose functionality and capacity
      • High priority channels – short latency channels

      EMBR – System Gain

      • System gain: system parameter indicating
            how much Path Loss can be tolerated

      • Three different antenna configurations:
              • EMBR-179 (monopole antennas)

              • EMBR-189 (helix antennas)

              • EMBR-201 (helix antennas

      • Line of Sight path loss at 10 km (5 GHz):
            128 dB
