    MIMO Fundamentals Antenna Configurations

    Leading the MIMO Revolution

    MIMO Fundamentals

    Traditional systems use a 2 dimensional signaling space: Time and Frequency

    MIMO systems enable the transmission of multiple signals at the same time and frequency by exploiting a 3rd dimension: Space

    Compared to SISO, MIMO provided several benefits: Higher data throughput

    Improved range and robustness

    Lower output power for a given distance

    User can trade between these to achieve project goals

    MIMO Techniques Spatial Multiplexing

    Transmit a different data-set (stream) from each antenna

    All streams operate at the same frequency, mixing within the RF channel

    Sophisticated signal processing allows each individual stream to be recovered at the receiver

    Provides dramatic increase in throughput for a given channel size (higher data rates)

    Leading the MIMO Revolution

    MIMO Techniques Space Time Coding (STC)

    Transmit redundant, robustly-coded copies of data from all antennas Coded in time to avoid time-specific signal interruptions

    Coded in space by sending data over multiple signal paths

    Sophisticated signal processing allows data to be recovered at receiver

    Enables higher probability of successful data transmission in all environments (improved robustness)

    Unattended Ground Sensors US MCWL TNS2

    Leading the MIMO Revolution

    The test went very well for the sensors. It is in very large part due to the exceptional performance of the Silvus radios. In the 6 years I have been doing ground sensors, the one common weakness has always been the radio. Silvus is a huge step up from any other radio we have used thus far for the application of transmitting video data and for operation in challenging environments. MCWL Project Officer

    SC3500 radios performed exceptionally well exceeding my expectations. Video was clear and not glitchy and the Henery GUI was easier to use as a result of low wait times in messaging between the Host TRC and the RIGSS Hubs Excerpts from the TNS2 report

    Unmanned Ground Vehicles Stereo 3D Video

    Providing SRI with high bandwidth comms for 3D HD video

    The Silvus MIMO radio is the only radio we found that will allow us to operate the Taurus and provide the EOD operator the ability to effectively utilize the system at a safe NLOS standoff distance. We tried other communications systems and they simply did not work. -Tom Low, Director, SRI International.
