COFDM

“C”: Coding a.k.a. Forward Error Correction – Convolutional Code with Viterbi for resilience against burst errors

– Retransmission for additional protection against block errors

“OFDM”: Multiple RF Carriers – Slower symbol rates – enhanced robustness in mobile, high multipath,

and non-LOS applications

– Immunity to frequency selective fading

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)

MANET (Mobile Ad-hoc Networking)

• Intelligently routes traffic using Silvus’ advanced networking algorithms

• Self-healing, self-forming mesh

– Dozens of units (20~50) supported today

– Large-scale algorithms in development (100’s of units)

• De-centralized topology

– Administrator access at any node

– No central point of failure

• High capacity – Up to 85Mbps

– 100’s of Mbps for large scale mesh

• Low latency (<10mS per hop)

Leading the MIMO Revolution

MN-MIMO Tying it All Together

Leading the MIMO Revolution

• MN-MIMO is Silvus’ proprietary waveform which blends MIMO, COFDM, and MANET technologies

• 62 discrete MCS (Modulation Coding Schemes), each with a unique combination of modulation parameters and MIMO techniques

• MCS are optimized to provide maximum data throughput in a variety of channel environments

• Radio adapts to environment by shifting gracefully and seamlessly between MCS to maintain optimum throughput as conditions change

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
