  • 1. Solving the Spectrum Crisis What is Cognitive Radio? An Overview of Cognitive Radio Network Technology November 2012xG® and xMax® are registered trademarks of xG Technology, Inc. Copyright 2012, All Rights Reserved. www.xgtechnology.com 1
  • 2. What Is Cognitive Radio?  Cognitive radio networks, like xG’s xMax system, represent an innovative approach to wireless engineering in which radios are designed with an unprecedented level of intelligence and agility  Cognitive radios are able to monitor, sense, and detect the conditions of their operating environment, and dynamically reconfigure their own characteristics to best match those conditions  Cognitive radio technology enables radio devices to use spectrum (i.e., radio frequencies) in entirely new and sophisticated ways xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 3. How Cognitive Radio Works  Using complex calculations, cognitive radios can identify potential impairments to communications quality in their environment, for example, interference, path loss, shadowing and multipath fading  They can then adjust their transmitting parameters, such as power output, frequency, and modulation to ensure an optimized communications experience for users xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 4. Cognitive Radios vs. Conventional Radios Conventional (“dumb”)Radios  Designed with the assumption that they were operating in interference-free spectrum  Unable to dynamically change parameters, channels or spectrum bands in response to interference  View congested radio spectrum as essentially unusable for communications due to heavy interference xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 5. Cognitive Radios vs. Conventional Radios Cognitive Radios  xMax cognitive radios have been engineered from the ground up to function in challenging conditions  Can view their environment in great detail, allowing them to quickly identify unused “gaps” in spectrum that are not being used  Can instantly find and tune to other spectrum if interference is detected on the frequencies being used (example - xMax samples, detects and determines if interference has reached unacceptable levels up to 33 times a second) xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 6. Cognitive Radios vs. Conventional Radios  Cognitive radios can use frequencies and find available bandwidth where other radios can only see static  xMax uses Dynamic Spectrum Access (DSA) to identify spectrum not being used, detects and mitigates interference, locks on a signal, and sends/receives  Increases throughput and range while minimizing interference xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 7. xMax Cognitive Radios ImproveSpectrum Efficiency  Can access unused frequencies to extract more wireless bandwidth  “Sees through” the spectrum clutter, eliminates interference, and allows optimal use of licensed and unlicensed spectrum  Designed to be frequency agnostic – its cognitive “identify and utilize” spectrum sensing technology can be used to power radios in any frequency band  Is able to exploit both licensed and/or free unlicensed spectrum, i.e., delivers a solution to users who have spectrum, and those who do not xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 8. Why Cognitive Radio is Important  Demand for mobile data services is expected to outstrip network capacity by as early as 2013  U.S. commercial networks are operating at 80% of total capacity, with 26% at full capacity  Reclaiming and reallocating needed spectrum in traditional ways takes years and costs billions  Cognitive radio represents a technology solution to increasing spectrum capacity and utilization xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 9. Cognitive Radio Uses  Incumbent Wireless Carriers: allows incumbent wireless providers to dramatically increase capacity of their networks and reduce interference  Rural Broadband Telcos: can help independent local providers overcome the obstacle of high cost/scarcity of spectrum to deploying wireless in underserved rural markets  Department of Defense/Military Applications: satisfies the need for a mobile, interference-resistant, scalable, frequency agile, cost-efficient wireless system  Public Safety: provides resilience and continuity of operations in wireless- impaired environments that is NOT AVAILABLE from commercial wireless systems  Utilities/Smart Grids: provides an efficient means of measuring and reporting usage  Mobile Content Providers: gives content providers (Google, Facebook, etc.) control of their own content delivery systems  Cable Markets: allows operators without spectrum to have a competitive entry into the wireless market xG® and xMax® are registered trademarks of xG Technology, Inc.

  • 13. Cognitive Radio: Experts’ Perspectives“The only way to solve people’s need to communicate wirelessly is by new technology. You can’tcreate new spectrum. “ Dr. Martin Cooper, past president of Motorola and inventor of the cell phone“xG has leading-edge products, solutions and capabilities in cognitive radio that solve a very realand growing concern. The explosive proliferation of bandwidth-consuming devices will onlyaccelerate the need for the cognitive radio technology xG is pioneering.” Jack Grubman, TMT Industry Expert. 2012“Cognitive-radio technology from xG Technology is a ‘potential game changer’ in battlefieldcommunications based on its flexible deployment model and ability to operate in spectralenvironments fraught with interference and targeted jamming.” Mike McCarthy, Director of Operations, Brigade Modernization Command, CERDEC, 2011“Unlike other cognitive radio systems currently being trialed, xMax features advanced inter-ference detection and avoidance capabilities designed to work around both intentional andunintentional interference.” Andrew Seybold, Mobile Wireless Consultant, 2011“In areas with no cost-effective broadband coverage, xG has the ability to deploy a cost effective,full-function cellular system serving government and/or consumer communications needs andopen new possibilities for operators.” Craig Mathias, International Expert in Wireless Communications, 2011“There are no realistic alternatives to xMax for a business wishing to deploy a dedicated mobilenetwork without owning a spectrum license.” PA Consulting Group Report, 2010 xG® and xMax® are registered trademarks of xG Technology, Inc.
