Free Space Optics and Wireless Broadband Radio Frequency Technology: Bringing High-Speed Network Access to the Last Mile
Manufacturer: Storming Media ProductGroup: Book Binding: Spiral-bound ASIN: 1423509889 |
Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA DEPT OF COMPUTER SCIENCE report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A375304. The abstract provided by the Pentagon follows: Existing copper phone and cable infrastructure no longer provide the required broadband for today's emerging applications. Homes and businesses in the "last mile" require the same access to broadband speeds available inside the fiber optic ring. It is not economically feasible, however, to bring fiber optic cable to each and every home and business in the "last mile." Free Space Optics and Wireless Broadband Radio Frequency are two technologies gaining popularity as an alternative broadband infrastructure. Free Space Optics uses lasers and Wireless Broadband uses Radio Frequency waves to send large amounts of data from on place to another. Both are wireless technologies that use free space. As a result, they are quickly deployed, easily scaled, and cheaper to install and upgrade than wired infrastructures. These characteristics support missions of the Armed Forces in which wire-bound infrastructure is not dependable, is impractical to build and maintain, or requires a high degree of mobility. This thesis address the "last mile" problem including why current infrastructure will not provide a broadband solution. free Space Optics and Wireless Broadband Radio Frequency technologies are explored and discussed. Finally, an economic analysis of alternative network designs utilizing the two emerging technologies is applied to a fictitious city with a population of one million.

Free Space Optics Communication for Mobile Military Platforms
Manufacturer: Storming Media ProductGroup: Book Binding: Spiral-bound ASIN: 1423513525 |
Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A064024. The abstract provided by the Pentagon follows: Free Space Optics (FSO) is widely regarded as the next-generation high-speed wireless communication technology. FSO has demonstrated its capability to deliver data faster than any other state-of-the-art wireless communication technology. Today, terrestrial FSO links are able to reach 150 kilometers; unmultiplexed data rates of 2.5 Gbps have been achieved; Acquisition, Pointing, and Tracking (APT) systems have been successfully deployed between communication satellites; and carrier-class availability are being offered by FSO vendors. However, FSO has not seen widespread use in the military. This is attributed to the fact that military platforms are largely mobile, while the progress in the commercial arena has largely been confined to links between fixed sites. This thesis analyzes the features of FSO technology while being mindful of how these apply to the military. These features include the bandwidth, spectrum use, bit error rates, communications security, free- space loss, and power consumption. The limitations and challenges presented by atmospheric effects, directional precision, line-of-sight obstructions, and laser safety are also studied. A final section will look at the acquisition, pointing, and tracking mechanisms that are necessary for deploying FSO on mobile platforms.

Free Space Optics Communication for Navy Surface Ship Platforms
Manufacturer: Storming Media ProductGroup: Book Binding: Spiral-bound ASIN: 1423515587 |
Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A043224. The abstract provided by the Pentagon follows: Free Space Optics (FSO) technology is an alternative broadband technology, which provides fast, secure and reliable data transmission. The FSO systems are being used for commercial systems between fixed sites and are being considered for military systems because of their inherent benefits, which are security and high data rates. In military communications security is the first priority. The small divergence of the laser beam makes FSO systems more secure than the existing radio frequency (RF) based wireless systems, because it is highly difficult to detect and intercept a laser beam due to the nature of the laser and the small divergence angle of the transmitter. However, FSO implementation on mobile platforms such as ships is still challenging. This thesis analyzes the feasibility of deploying FSO system on navy surface ships. It discusses the FSO technology and the latest studies in maritime optical communication links. In addition, the benefits and challenges of FSO technology specific to this study are studied. The final section discusses the required systems to improve the performance of FSO systems on ships. The thesis concludes that FSO technology, while not ready for deployment, looks very promising for the near future.

A Low-Cost, Man-Portable, Free-Space Optics Communications Device for Ethernet Applications
Manufacturer: Storming Media ProductGroup: Book Binding: Spiral-bound ASIN: 1423586867 |
Product Description
This is a NAVAL POSTGRADUATE SCHOOL MONTEREY CA report procured by the Pentagon and made available for public release. It has been reproduced in the best form available to the Pentagon. It is not spiral-bound, but rather assembled with Velobinding in a soft, white linen cover. The Storming Media report number is A178924. The abstract provided by the Pentagon follows: This thesis sought to design and implement a low-cost, portable, Free-Space Optics (FSO) communications device for Ethernet applications. Under some circumstances such a device would have utility at a Combat Operations Center (COC), a Field Artillery Position, or wherever else fiber optic cable is used in garrison or field. The design was based on commercial off the shelf components originally designed for fiber optic applications. Based on a 155 megabits per second (Mbps) media converter, the design used two fiber optic transceivers, coupled to collimating lenses to pass data over free-space. Sustained data rate of 100 Mbps was achieved with full network functionality on the optical bench with a low-power (0.5mW) laser diode transmitter without focusing optics on the receiver. The laser diode power(mounted on device), was measured with acceptable losses up to 300 ft during testing using a photodiode with focusing optics. The findings indicate that the system with proper collecting optics could be optimized for free-space communication at short to moderate ranges.

Free Space Optics 2001: A Networking Odyssey
Yankee Group Manufacturer: MarketResearch.com ProductGroup: Book Binding: Digital ASIN: B000068IQL Release Date: 2001-11-01 |
Book Description
Since Free Space Optics (FSO) operates in an unlicensed frequency, and is a comparatively cheap, easy-to-deploy, and very-high-capacity broadband solution, enterprises around the globe have been using it as a means of connecting dispersed office LANs, and for redundant fiber backup. These applications are a crucial part of the market for FSO vendors, and have helped endorse the benefits of the technology; however, there are a multitude of other applications within the service provider segment, such as metro ring extension and Gigabit Ethernet backhaul, that will generate major revenue for the FSO players. But the deployment of FSO in carrier networks must be carefully assessed, as the technology has some inherent limitations: FSO is a line-of-sight (LOS) technology The reliability of an FSO link is affected by fog, scintillation, and building sway. Links must be constructed at distances ranging from 820.25 feet (250 meters) to 6,562 feet (2 km) in order to decrease susceptibility to interference.Download Description

A bluff! Some of my friends secured that old unused van and wished to make the attempt. But I considered it impractical without the concurrence of a number of unusual circumstances. However, I found it useful to carry out that attempted escape and give it the widest publicity. An audaciously planned escape, though not completed, gave to the succeeding one the character of reality simply by anticipation.Customer Reviews:

Arsene Lupin - robs the rich and gives to the reader........2002-01-11
Although these nine loosely-connected mysteries are pure fantasy, their detail and context open out the Belle Epoque milieu in which they are set. One of the major themes is that the 'respectable' bourgoisie Lupin robs are often as dishonest and even criminal as he, indulging in the illegal speculations/swindles rife at the time or organising elaborate charades to conceal financial decline. The invidiousness of social inequality is a factor in Lupin's psychological make-up. The antiquity of French history and national character is in conflict with the disruption of modernity (telephones, photographs, automobiles etc.). The vulnerability of the bourgeoisie contrasts with a democratising popular press avidly chronicling Lupin's every move, making him 'our national thief'.
I don't want to get too solemn, such is the breezy pleasure of this book, but I believe 'Lupin' is more than simply an engaging riposte to Sherlock Holmes; Lupin is more than someone who pilfers from the rich. Whereas most crime literature seeks to re-order a violated society through a central, reliable, narrational consciousness embodied in the figure of the detective, 'Lupin' disrupts order at every opportunity. Lupin's facility with disguise is matched by his disruptions of the text, which changes narrator and point-of-view without warning, Lupin himself often betraying the reader's trust by assuming the first-person on false pretences. With wit, playfulness and a light touch, leBlanc undermines our certainties as readers, just as Lupin does his victims, filling each tale with alternative narratives, jarring tones, shifting modes, unfulfilled expectations. Lupin is always taking his bow, leaving the stage and slipping away, as terrified by his own lack of a recognisable identity as he terrifies everyone else. For omnipotence and fame come at a price - existential dread and sexual impotence: the penetration of homes and homosocial company must substitute for failed relationships with women.
