Why cognitive radio mattersSpectrum challenges for the warfighter are Civilian and host nation operators aremultiplied by global operations and jamming demanding additional spectrum resources for(intentional & unintentional) data hungry consumers Inundated Global Spectrum Existing Spectrum Allocations Exponential globalSpectrum Allocations challenges Existing spectrum management Dynamic Spectrum Access (DSA) and Cognitive Radio • Identify and access unused spectrum globally Solution • Advanced interference detection, mitigation and avoidance • Connectivity and capacity – when and where needed The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 3. Commercial vs. military challenges Commercial Environment Military Environment Massive demand for wireless applications Issue every soldier a cell phone Limited supply of spectrum No new spectrum – relocate/share existing? Lack of spectrum precludes new market Host nation spectrum access entry Expensive service plans Expensive service plans Mobility On the move Smartphone adoption Smartphone as force multiplier► Shared pursuit of a cost-effective mobile voice and broadband capability using a single set of IP infrastructure► Flexible all-IP architecture allows xMax to answer commercial and unique military requirements – “future-proof” The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 5. Traditional approach …► Cognitive radio identifies spectrum that is not being fully used …► … and dynamically tunes to those frequencies if interference is detected on channel currently in use (DSA)► Priority is to minimize interference to other devices by ‘running away’► Often, alternative channel choice preset (and can be predicted and hacked/jammed) The focus on ‘running away’ from interference does a poor job of optimizing all available spectrum resources i.e., Grey/Black Spaces, not “White Spaces” The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 6. … vs. xMax approach► Advanced sensing and multi-spatial interference mitigation and avoidance technologies offer the ability − both to mitigate interference, which extends “dwell time” on the current frequency … − … and avoid interference by hopping to other ‘cleaner’ channel instantly if interference is overwhelming and performance falls below set thresholds (within 40ms)► In addition, to maximize throughput (or range) and minimize interference, xMax dynamically adapts network architecture to real-time conditions − power output − modulation − channel plan − network protocol xG’s cognitive radio network solution dynamically optimizes spectrum utilization through opportunistic use of all available resources The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 7. xMax cognitive radio► xMax layered cognitive approach − spectrum sensing: interference based detection of transmitters (background scan every 20ms) − spatial processing: MIMO technologies allow resistance to interferers. Optimize SNR using multiple antenna processing to improve link budget and data rates. Also used to track and cancel interference from multiple mobile transmitters using sophisticated multi-spatial signal processing algorithms − spectrum sharing: able to operate in crowded shared spectrum (ISM, UNI II etc.). Detect interferers, mitigate them or avoid them by changing operating parameters or frequencies − spectrum management: capture the best available spectrum for use at any time. Can add capacity anywhere, any time without using existing frequencies − spectrum mobility: use spectrum dynamically (DSA). Mobile user terminals and base stations can decide to change bands where they operate “Unlike other cognitive radio systems currently being trialed, xMax features advanced interference detection and avoidance capabilities designed to work around both intentional and unintentional interference. ” – White Paper: “ New Approaches To Optimizing Radio Spectrum” (Andrew Seybold), December 2011 The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 13. Game changing capabilities Military tests of xG Technology solution could have domestic implications Nov 16, 2011 5:58 PM, By Donny Jackson (donald.jackson@penton.com) . . . .commercial-wireless executives have been outspoken in proclaiming a “spectrum crisis” that federal policymakers have been working feverishly to resolve . . .. . . . ., the military has opted to conduct its own tests . . .And the xMax system tested at Fort Bliss was “exceptionally impressive,” according to Mike McCarthy, director of operations for the Mission Command Complex at the Brigade Modernization Command at Fort BlissMcCarthy said the military plans to conduct further tests in the spring to “push that system as far as we can push it”“The results of these tests should be of interest to many, not just those in the military. If the xMax system proves that it can providereliable communications over unlicensed spectrum, the utility of unlicensed bands and prospects for wireless communicationsoperating in the TV white spaces could be transformed in the near future” The information presented herein is confidential and subject to change without notice. xG® and xMax® are registered trademarks of xG Technology, Inc.
