Cognitive Radio for Public Safety Applications September 2012

  1. 1. xMax for Public Safety,Homeland Security and DACAApplicationsPresentation to the FCCSeptember, 2012 The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  2. 2. Objectives ► DACA and other Public Safety Initiatives ► Cognitive Radio Helps Realize These Initiatives ► xMax & Demo Overview ► 4 Demos Combining xMax and Cellular Networks: – Broadband – Voice/text – Location Tracking – Interference Mitigation The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  3. 3. Objective ► Review Current State of the Art in Cognitive Radio Technology ► Show xMax Supports FCC Spectrum Sharing and DACA Initiatives. ► Demonstrate Prototype xMax 2.0 Gear and Technology ► Show Commercial Boards and Finished Mock-ups The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  4. 4. DACA► Purpose: address the gap during the first 72 hours after a catastrophic event when communications may be disrupted or completely disabled► Method: facilitate emergency response by rapidly restoring communications capabilities in the immediate aftermath of a catastrophic event. Responses to the DACA PN raised issues with: interference coordination, mitigation and spectrum management with commercial and public safety networks before and during DACA deployment The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  5. 5. Cognitive Radio ► Cognitive systems are able to identify spectrum that is not being used, and to tune to those frequencies to transmit and/or receive signals. ► Have the ability to instantly find unused spectrum if interference is detected. ► Can adapt their own power output, modulation, channel plan, network protocol, etc. dynamically to maximize throughput. ► Issue: there may not be better channels to operate upon Interference Mitigation, not just interference Avoidance, is required for Emergency Communications in limited spectrum scenarios The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  6. 6. Application of Cognitive Radio ► Rapid deployment to extend or even replace commercial cellular, PS functionality. Complimentary capability, capacity, devices, etc. (DACA, Tactical & Disaster Applications) ► Seamless support for existing devices & apps when cellular capacity is not available – Focused Overload – Snowmagedon, Coastal Earthquake – Disasters – Hurricane, 911, War, Jamming, Hot Cut ► 3G/4G overlay solutions require licensed 3G/4G spectrum in order to operate – no uncoordinated use on same frequency – Carriers do not support/allow in populated areas – DACA PN filings with FCC – D Block LTE overlay will require multi-agency coordination within 700 MHz band xMax can deliver a licensed spectrum experience using unlicensed spectrum with no interference to existing networks The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  9. 9. Field Validation “These are major-league Urban/Suburban - Ft. Lauderdale, Florida pioneers who have built – fully mobile 32 mile2 network something that works well.“ – densely populated —Craig Mathias, – interference-rich environment Wireless Analyst, 2010 – extensive testing has allowed continual system performance enhancement and development of Ft. Lauderdale, FL robust system Military - US Army - TX, NM, NJ – lab validated (CERDEC) – garrison enterprise solution White Sands, NM – tactical cellular – austere desert Rural – Lewisville, Arkansas – underserved market – low noise, excellent range Lewisville, AR xG® and xMax® are registered trademarks of xG Technology, Inc.

  12. 12. Interference Avoidance Dynamic Spectrum Access ► Access point and xMod are frequency agile. Either can move channel in response to interference ► Devices background channel scan every 20 mSec cycle for available channels ► Comm links migrate to another channel if interference is encountered. ► Existing users not impacted “I ran an excursion where we attempted to jam it with conventional military jamming systems, and we were unable to do it, xMax was able to stay ahead of the jammers that were trying to attack it and kept the communications systems up and operational throughout the two weeks that I ran the jammers”.

  13. 13. xMax Interference Mitigation ► Spatial projection processing to remove interference ► xMax can mitigate narrow and wideband interference, burst and continuous time interference xG algorithm uses multiple dimensions of receive signals ► Interference mitigation results from 2X4 MIMO The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  18. 18. Critical Needs Drivers► Commercial Networks “demanding” more capacity – No virgin spectrum left to auction – Against overlay use by PS networks (DACA response)► Public Safety, DHS, FEMA, etc requiring more wireless communications during a response► Immediate tactical wireless capacity and availability critical in disaster when existing infrastructure is compromisedClearing existing Federal spectrum for exclusive use not practical or economical (NTIA report) Shared spectrum access appears to be best solution!
