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 /2/ 17-Mar-11

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 /3/ 17-Mar-11

EMBR Design • Frequency Band: 4.900 – 5.875 GHz • Bandwidth: 20 MHz • User Datarates: Up to 6Mbps • Output power control /4/ 17-Mar-11

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 /5/ 17-Mar-11
