| | JEC Hearing on Radio Frequency Weapons |
 | | Because of the rate of change of technology, in communications, computers and sensors as well as in lasers and radio frequency technology, the complexities of the issues are fast-moving. | | | In particular, ATD evaluates the capabilities of technologies, including radio frequency weapon technologies, to establish their significance to the operability of our sophisticated electronics. | | | If the signal was tuned to the operating frequency of a targeted radio receiver, for example, one would assume that if enough power was provided in the radiated beam directed at the target's radio antenna, that the radio's "front-end", that part directly connected to the antenna, could be heated sufficiently to burn it out. |

| | What is this frequency-hopping? |
| | By changing frequencies every 20 milliseconds, the GeneralCommunications.com FHSS radios avoid most interference that may be present within its frequency band, and by sending data over and over again, gets the data through, even if some packets may have been lost to interference. | | | A pre-determined algorithm is utilized to maintain the synchronization between radios as they hop sequentially through a set pattern of frequencies determined by the algorithm. | | | The RAD-ISM-900 transceivers can be used on the license-free 902-928MHz band and proven Frequency Hopping Spread Spectrum technology designed for use in high frequency environments. |

| | CommsDesign - Sharing spectrum the smarter way |
| | Cognitive radio — one that can sense its environment and location and then alter its power, frequency, modulation and other parameters so as to dynamically reuse available spectrum — is emerging, but some are already calling it the holy grail of wireless design. | | | Derived from a doctoral thesis submitted in May 2000 by Joseph Mitola, who is now at work on the military's cognitive-radio initiative, CR could in theory allow multidimensional reuse of spectrum in space, frequency and time, obliterating the spectrum and bandwidth limitations that have slowed broadband wireless development in the United States and elsewhere. | | | CR "is a radio that's aware of and can sense its environment; learn from its environment; and perform functions for its user that best serve its user," said Bruce Fette, chief scientist at General Dynamics Decision Systems and technical committee chairman of the SDR Forum. |

| | In the illustration, the input signal is inverted at frequency 3.3kHz. | | | This process relocates the power level of each input frequency to a new position, calculated as the difference between the original frequency and the inversion frequency. | | | The algorithm dictates the location of the new inversion frequency, and the rate at which the frequency changes. |

| | Cognitive radio: a smarter way to use radio frequencies — JSCMS |
| | Traditionally, radios were hardwired to operate at a particular power and frequency, and once a station was assigned a frequency, no other station could use it. | | | This process of negotiation is the concept behind a technology called cognitive radio, a way to share unused spectrum. | | | Over the years, as engineers built radios in cheaper and smaller packages, it became possible to build intelligence into them, making the idea of sharing frequencies possible. |
